Basic Principles Related to Human Body

Deviating from the known approaches of our times to human body, Ayurveda studies the human body more from a functional point of view. In Ayurveda, human body is not considered just as a mass of organs, systems and tissues; but the complex mechanism’ of myriad functions taking place both at physical and mental level are evaluated and described. 


In order to explain the functional complexity of human body, Ayurveda propounded few basic doctrines. These doctrines visualize the functional units of the body to be formed by three Dosha (humours), seven Dhatu (tissues) and Mala (metabolic end products) which are in equilibrium during health.

The human body is more complex than any other form of life as on date. Purusha –the Human body is the aggregate of 25 elements, together with Atma –the spirit or soul-

 

DOSHAS

Ayurveda identifies that, the functional integrity of human body is governed by a balance of three specific humors, termed as Doshas. Practically speaking, their equilibrium is not a static one but dynamic in nature.

The word Dosha is derived from the root dus, which sounds similar to the English prefix ‘dys’. If translated, the word dosha would mean a "fault", "stain", and "transgression" against the cosmic rhythm or an inaccuracy that leads to chaos. However, in the context of Ayurveda philosophy, doshas are not per se harmful. Rather, they seem to be called doshas for they are prone to undergo chaos or aberrations under disturbed circumstances.

VATA DOSHA

If Doshas are considered to be manifestations of energy, Vata dosha can rightly be equated to a Kinetic Energy. The origin of the word Vata can be traced to "that which moves" and it fits the dosha to the letter.

Vata is the initiator of all life processes that are dynamic in nature. It represents the impulse in the communication network of the body – from brain to periphery, from tissue to tissue and cell to cell. Vata is responsible for perception (pain), transmission and reaction. It brings a thought from the memory to consciousness, and transfers current experiences into memories. It inspires speech and is the base for laughter and exaltation.

In human physiology Vata governs all such functions that involve somatic initiation and dynamism:-

* Vata initiates and transmits all stimuli.
* Vata governs the intestinal motility facilitating the downward movement of food we consume.
* Vata governs whole process of respiration.
* Vata governs the movement of heart. Thus, it takes off delivering the nutrients to all cells in our body. It governs the collection and transport of carbon dioxide and other wastes from body.
* Vata governs our intellectual perception, imagination and motivation.

In order to explain more intricate details of these doshas, Ayurvedic doctrines classified each of them in five sub-doshas; like vata dosha in "Prana, Udana, Vyana, Samana, Apana"

PITTA DOSHA

Pitta represents the somatic energy in all living forms. In a living cell, it converts the ingested food into energy. Pitta maintains the natural pigmentation/colour of cells. Pitta is primarily distributed in the regions of umbilicus, the stomach and small intestines, sweat, lymph, blood, plasma, eyes and skin.

Pitta dosha, as the name suggests, is responsible for all types of transformation in the body. Pitta controls digestion of food in the gut as well as the conversion of light rays which fall on the retina to electrical impulses which in turn are carried by the optic nerve for processing in the brain. A strong Pitta in the brain allows good processing of the information, thereby leading to a certain maturity in comprehension.

If vata dosha controls exultation and laughter, Pitta dosha controls emotions like anger, fear and bravado. In keeping with its effect on the brain, Pitta is responsible for positive and action-oriented emotions. Because it hones the intelligence, Pitta gives rise to greed and may be said to be responsible for Machiavellian tendencies in humans.

In human body, it governs an array of complex activities concerning digestion and metabolism; -

* Pitta generates and maintains some natural urges, like hunger, thirst.
* Pitta represents various secretions, responsible for digestion.
* Pitta regulates the complexion and suppleness of skin
* Pitta is instrumental in the maintenance of vision.
* Pitta supports certain mental phenomena like intellectual comprehension, Conviction, courage and valour. 
* Human body is maintained at a constant temperature of 37o C irrespective of temperature in outer environment. This phenomena is called as "Thermo-regulation" and constitutes an important function of Pitta. 

In order to explain more intricate details of these doshas, Ayurvedic doctrines classified each of them in five sub-doshas like pitta dosha in "Pachaka, Ranjaka, Sadhaka, Alochaka, Bhrajaka"

KAPHA DOSHA

In human body, Kapha is primarily distributed in chest, throat, head, plasma, fatty deposition and tongue. If Vata is kinetic energy then Kapha is potential energy.

It gives mental strength, as well as resistance to disease. It gives firmness to joints while keeping them lubricated. It also imparts sexual potency.

* Like in living cell, Kapha maintains the structural integrity and confines Individual organs to their specific location.
* It protects the bodily organs against physiological injury.
* Kapha imparts immunity against diseases.
* It maintains the fluid balance.
* Mental phenomenon like, intellectual stability, determinations are governed by Kapha.

In order to explain more intricate details of these doshas, Ayurvedic doctrines classified each of them in five sub-doshas like kapha dosha in "Avlambaka, Kedaka, Bodhaka, Tarpaka, Sleshaka".

DHATUS

Dhatus are structural blocks of the body. They constitute the body -termed as S’areera. The most important difference between the Doshas and the Dhatus is that the latter perform functions under the influence of the Doshas

The word Dhatu means ‘support’, in Sanskrit. Tissues therefore form the infrastructure of the body. There are Seven types of such structural elements that, constitute human body. 

Rasa :- It represents the primary constitution of human body. Water is a major constituent of human body. Such water is present in human body, both as extra cellular and intracellular fluid content. Rasa dhatu-the first of seven structural elements refers to both extra cellular and intracellular portions of fluid in the body.

Rakta :- The word Rakta refers to Blood. Thus, Rakta dhatu represents the blood, which includes its cellular components. Blood is perceived as a special type of tissue, in modern concepts of physiology also. 

Mamsa :- The muscular tissue, which constitutes many internal organs as well as the muscles, is referred to as Mamsa.

Medas :- Medo-dhatu is referred to as adipose tissue. Commonly, adipose tissue comprises of all deposits of fat-distributed in the body. 

Asthi :- All the bones in human body are composed of a tissue termed as osseous tissue. All such tissue is termed as Asthi dhatu in Ayurveda. Asthi dhatu also include all cartilaginous structure in the body. 

Majja :- Majja is bone marrow. A special type tissue called myeloid tissue forms bone marrow. 

Sukra :- Sukra represents the reproductive elements. This includes the sperm in males and ovum in females. Apart from these elements, Sukra also refers to cellular reproductive elements.

TISSUE NUTRITION IN AYURVEDA

The mechanism involved in the maintenance of nutrition to these 7 structural elements is explained in a concept; known as " Dhatuparinama Vada".

As per this concept, the ingested food is digested in digestive tract and nutrient and waste parts are segregated. This kind of digestion is carried out primarily, by Pachaka Pitta-which is the digestive moiety of Pitta. 

Samana Vata and Kledaka Kapha, which are the functional moieties of Vata and Kapha respectively, located in digestive system, support Pachaka Pitta in this process. In view of its fire like role, Pachaka Pitta is referred to as "Pachakagni".

This process can be explained very simply, with an analogy of "Cooking". We need the help of air, fire and water to cook food properly, in our day today practice. In our body, functions of air, fire and water are played by Samana Vata, Pachaka Pitta and Kledaka Kapha respectively. A right degree of cooking is possible when the air, fire and water are just, at optimal level. 

After digestion, the nutrients and wastes from ingested food are segregated. The digested food, termed as " Ahar Ras" is a blend nutrients needed for all 7 dhatus.

Nutritional demands of different dhatus are variable and each dhatu derives its selective nutrients, as this "Ahar Ras" is circulated through out the body through circulatng channels. The selective nutrient, picked-up by each Dhatu, undergoes further metabolism in respective tissues.

Such metabolism, within a Dhatu is carried out with the help of specific moieties of Pitta located in respective dhatus. The Pitta element, working within a particular dhatu, is called as Dhatwagni.

During this process, each Dhatu produces some kind of metabolic waste again, from its selective nutrients. Such wastes produced by a Dhatu are called Dhatumala. If not eliminated from time to time these wastes from tissues become toxic. Therefore, Ayurveda recommends periodical "cleansing" of body

MALAS

Mala’s are excretory elements. These are three and termed as Thrimalas-

(1) Pureesha (The Faeces)
(2) Mutra (The Urine)
(3) Sweda (The Sweat)

The word Thrimala is used, to refer 3 types of excretory systems present in the body and not just the excreta. Mala can be translated as metabolic end products. This means that each cell which is a living factory will produce, under the influence of the Doshas , wastes (mala) which in turn influence adversely the functions of the Dhatus that produce them.

Thus Dosha, Dhatu and Mala form a tripod of health

GAYANENDRIYAS


Gyanendriyas are sensory organs. They are the organs of perception. Since they are the tools to acquire –"gyana" –the knowledge or information, they are termed so. They are five in numbers-

Akshi (The Eyes)
Karna (The Ears)
Nasika (The Nostrils)
Jihwa (The Tongue)
Twacha (The Skin)

These five are termed as Indriyadhisthana. It means, the prime location of sensory perception. Every Gyanendriya is a complex system and not just, one or two organs. Each of these Gyanendriyas have a definite object of perception. This object of a sensory organ is termed as Indriyartha

KARMENDRIYAS

Pada (The Feet)
Hasta (The Hands)
Vagindriya (The sense of speech)
Paya (The Anus)
Upastha (The Genetalia)

The name of karmendriya includes the entire structure and functional mechanism of that particular organ. The function of a karmendriya is referred to as Indriyartha.

MANA

Manas or the mind is considered as 11th Indriya by Ayurveda. By virtue of its functions, Manas performs the functions of both Gyanendriya, the sensory organs and Karmendriya, the motor organs.

It has two specific characters, viz. Ekatwa (solitude or seclusion) and Anutwam (subtleness). Because of its Subtleness, Manas can move swiftly. For its swiftness, Manas is considered as the fastest object in the universe.

Manas are an entity that is responsible for generation of knowledge. It plays an instrumental role in the perception of Indriyartha. For this purpose, it conjugates itself, with the respective gyanendriya and receives sensory signals.

Gyanendriya can’t perceive any type of knowledge on its own, without conjugating itself, with Manas or Mind. Also, it is important to note that, Manas can conjugate itself, with only one sense organ at a given point of time and not more than one. But, it can move from one organ to the other, swiftly-within a split second. Functioning of Karmendriyas also needs a conjugation with Manas

Apart from such dual role, Manas is also responsible for some more faculties. Analysis, Thinking, Imagination are some of such special functions of Manas.

BUDDHI

Buddhi is another constituent of Purusha. In terms of modern Psychology, Buddhi comprises intellect and will. It contemplates the circumstances that call for an action and provides rule of conduct. Will control the disposition, in harmony with the dictum from Buddhi

Manas has an ability to perceive various stimuli through Indriyas. Also, it can analyze them in terms of merits & demerits. Based on such analysis, Buddhi produces a decisive knowledge. Thus, Buddhi-the intellect is ultimate decision-maker

ATMA

The word Atma can be literally translated as Soul. Concept of Atma has been the central dogma of Indian Philosophy.

Atma conjugates with all the constituent elements of human body, which is eternal. Such conjugation of Atma is only restricted to the instruments (such as sensory organs, mind & intellect) but, not their with their deeds.

Atma is omnipresent. It is constituent among all forms of life. The biological functions of all living systems are attributed to the presence of Atma, in a body-where all other constituents are incorporated. 

 

 

What is Ayurveda?

Ayurveda is a holistic Indian system of medicine that uses a constitutional model. It works to provide a flexible guidance to attain a state of positive health. Its treatment and techniques is also flexible for people with health challenges.

Ayurveda is derived from two Sanskrit root words: Ayu, which means Life, and Veda, which means the Knowledge. Thus Ayurveda refers to the Science of life. 

The ancient rishis or seers of truth, discovered truth by means of religious practices & disciplines. Through intensive meditation, they manifested truth in their daily lives. Ayurvedic system of health is conversance of practical, philosophical & religious experiences of great sages.

Ayurveda is a fine blend of Science, Religion & Philosophy as well. We use the word religion to denote philosophical perceptions and discipline in conduct through which, the doors of perception open to all aspects of life. Through its scientific approach to human life, Ayurveda works to harness the intricate abilities of human body and mind. With its philosophical approach to human life, Ayurveda preaches us to recognize ourselves as miniscule component of this magnificent universe.

The physiological and pharmacological concepts of Ayurveda are structured in "whole- someness". Therefore, the Ayurvedic description of "human body" and the "drugs" are dealt from a holistic plane. Even their "interface" is identified from a holistic perspective.
 

 

Vedic Era:

India is known as Land of Vedas. The word Veda refers to True Knowledge. A number of guiding principles for preservation of health are mentioned in Vedas. However in Atharva Veda, such guiding principles, medicinal effects of herbs etc. occur more abundantly. Thus, Atharva Veda forms the structural foundation for emergence of Ayurveda, as a separate branch of science or knowledge.

It would be an arduous task to determine the time of origin for Vedas. Based on an astrological calculation, B.G.Tilak opined that, Rigveda (the first of four Vedas) originated between 6,000 and 4,000 B.C.

Historical descent of Ayurveda upto Indra could be termed as Vedic Era. It is believed that Maharishi Bhardwaj ventured to reach the heavens and sought the knowledge of Ayurveda for the benefit of mankind. Thus it is apparent that Ayurveda was not within the reach of mankind before Bhardwaj. He, in turn, taught this subject to others including Atreya.

According to another mythological belief, Lord Indra favoured the blessed Lord Dhanvantari with knowledge in Ayurveda. Dhanvantari, in years to come, became a renowned teacher in the art of surgery & taught this subject to his disciples. He was considered the "Patron Saint Of Surgery" and later elevated to divinity of classical medical wisdom. 

However, during Vedic Period, Ayurveda was not a separate branch of science. It would be logical to state that, evolution of Ayurveda started with compilation of health care information scattered in Vedas. Such beginning would have given a much wider scope for its evolution into an inter-disciplinary science (as Up-Veda) for application purposes.

 

Samhita Era:

The word "Samhita" means "Compilation of Knowledge". Thus the period in which process of compiling treatises on Ayurveda began is known as Samhita Era. 

The length of this period between Atreya to Gautam Buddha is generally termed as Samhita Era, in the history of Ayurveda.Based on the available evidence, Atreya’s period was considered to be around 1000 B.C. Thus Samhita Era is the span between 1000-6000 B.C. During this span, Ayurveda was enriched by a series of treatises by different rishis (sages). 

To the available evidences, Maharishi Krishnatreya initiated process of spreading knowledge. He was said to have knowledge of Ayurveda from his teacher Maharishi Bhardwaja. Atreya spread his knowledge while moving from one place to other, through out the country. So Maharishi Krishnatreya has acquired another name, Charaka (Char means to move and the one who moves is, Charaka). The Six Disciples of Atreya, Who developed the School of Medicine namely Agnivesha, Bhela, Jatukarna, Parasara, Harita and Ksharapani wrote samhita of their own (Shatbhishak Samhita). Of these the Agnivesha Samhita was well accepted and was propagated as the backbone of Ayurvedic Samhita (Compendia). 

Similarly, the Divodasa Dhanvantari, who developed School Of Surgery, had its disciples-Aupadhenava, Vaitarana, Aurabhara, Poushakalvata, Gopurarakshita and Sushruta. The Sushruta Samhita was written by Sushruta. It deals with a complete systematic approach to Shalya Kriya (General Surgery) & Shalakya Tantra (eyes, ear, throat & nose) The period of Sushruta Samhita is considered to be around 500 B.C. just before Buddhist Period.

The other available samhita that belongs to more or less the same period are Kashyapa Samhita, Bhela Samhita and Harita Samhita. During this period, it is interesting to note that most of the knowledge about drugs was centred on plants. 


Apparently by this time, Ayurveda was developed into a School of Medicine having eight branches of medical specialties- 

Ashtangas of Ayurveda:

 
1 Kaya Chikitsa - Internal medicine 
2 Balaroga Chikitsa - Paediatrics 
3 Shalya Chikitsa - General surgery 
4 Shalakya Chikitsa - Eye, Ear, Nose & Throat surgery 
5 Agada Tantra - Toxicology 
6 Rasayan Chikitsa - Science of Rejuvenation 
7 Vajikarana Chikitsa - Study & development of sexual power & fertility 
8 Bhoot Vidya - Psychiatry 

Buddhist Era

Probably in the history of Ayurveda, Buddhist Era could be stated as golden period. During this era, every branch of Ayurveda was nourished due to the contributions of different scholars. The period of Gautam Buddha is more or less accepted to be around 600 B.C. From that time onwards, Buddhist Era for the purposes of Ayurveda is considered up to 5th A.D.

Development of Ayurveda during Buddhist periods was due to an unequivocal support of Gautam Buddha himself. Buddha naturally considered Ayurveda as one of the very effective methods to alleviate human suffering and this ability was much closer to his philosophy.

By this time, Ayurveda in India took a major leap, by introducing an 8 years long professional course at Takshashila University (presently in Pakistan), around 700 B.C. Soon, Nalanda University also followed the course. 

Important personalities & Compilations in Buddhist Era: 

Vriddha Jeevaka


He had an admirable authority not only in Ayurveda, but also in many areas of contemporary knowledge. For his tremendous power of analysis, he was referred as Jnanavriddha (aged person in knowledge). Thus Jeevaka became familiar as Vriddha Jeevaka. He compiled a treatise covering the teachings of his teacher Kashyap, in the name of Kashyap Samhita. The text is also known as Vriddha Jeevakeeya Tantra – to commemorate the author.


Kashyapa Samhita

The treatise compiled during Buddhist Era has specialized in Bala Chikitsa (Paediatrics). It contains 9 volumes (Sthans) and 200 chapters. 

Jeevaka

Jeevaka was praised for his influential personality, generosity and spiritualism. Jeevaka was born to a prostitute near Patliputra (presently Patna) as an unwanted child and was thrown out as a neonate soon after his birth. The prince of that state by name Abhay brought him to the palace and ordered his maids to bring him up. Since the boy survived the rejection by his mother, he was named as Jeevaka. He studied Ayurveda under Bhikshu Atreya for 7 years, at Takshashila University. Jeevaka performed his career as a Surgeon. He treated Gautam Buddha for a chronic ailment by administering a purgation course. 

Nagarjuna

He was born in Amravati (presently in Guntur district of Andhra Pradesh) during 113 AD. As the dynasty nurtured Buddhism, Nagarjuna also became an ardent Buddhist and lived as a Buddhist saint. He also became the 13th chief (Dharmadhyaksha) of Buddhist saints. Though, Nagarjuna had traveled widely, he spent most of his life in Amravati and a near by hilly area –Sriparvata and its adjacent valley. This Sriparvata is also known as Nagarjuna Konda (the hill of Nagarjuna) and its valley is totally merged in the reservoir of a multipurpose project on River Krishna, named as Nagarjuna Sagar.

However, Nagarjuna’s contribution for Ayurveda comes from a different angle. He has conducted extensive studies on health applications of Mercury & other heavy metals. These studies, have entailed in the emergence of a new branch of Ayurveda, viz. Rasa Shastra or Alchemy. Ayurveda, in later periods used Mercury as well as other toxic metals as important components of pharmaceutical formulations.

The Mediaeval Era

For the purpose of Ayurveda history, mediaeval periods were spread through 8th century to 18th century A.D. During this span of 1000 years India, as a country passed through a series of sanguinary political upheavals, which were rather, unprecedented. On the other hand the scientific and cultural heritage of India also, was subjected to a closer and competitive impact.

Ayurveda as a science by that time was able to derive its conceptual and driving spirits from only Indian philosophy. There was hardly any scope to enrich itself, from the Trans-National approaches of health care, nor there is a clear evidence of its influence on any other upcoming system of medicine like, Chinese or Greek medicine. 

The Arabian Medicine, which had roots in Greece came into contact with Ayurveda only through invaders and emigrants to begin with, in 6th Century A.D. There were some Ayurvedic literatures translated by prominent scholars-

* Charak Samhita translated into Persian by Manka & later to Arabic by Abdulla-bin-Ali    as Sharaka..
* Sushruta Samhita translated into Arabic by Manka as Sushrud.
* Ashtanga Hridaya translated into Arabic by Ibun-Dhan as Astankar.
* Siddhayoga translated into Arabic by Ibun-Dhan as Sindhashtaq

Also in Firdausu’l Hikmat, authored by Ali-bin-Raban-al-Tabri (850 A.D.) gives a detailed account on Indian system of medicine towards the end of his work.

Around this time, the works of Avicenna (985-1040AD) enriched Greco-Arabic medicine. During later periods, his publication- The Cannon of Medicine (Spread in 5 volume) was taught in the medical institutions of many European countries and influenced the concept of medical sciences there.

Under difficult political situations, the scholars and practitioners of Ayurveda were unable to protect their valuable belongings- the Ayurvedic literature. They taught Ayurveda only to their sub lings and not to the really eligible students. These forced practices of Ayurvedic scholars, have set a new trend in motion, of Proprietary/Secret formulations, in the name of Anubhoot Yogas (formulations arrived at, -based on experience). 

By this time, the Hippocratic Medicine having spread into Europe in the name of Allopathy (To treat substance opposite the symptoms) made few important strides. In 1543, Andreas Versalis compiled a textbook on Human Anatomy. In 1590, Andreas Versalis compiled a textbook on Human Anatomy. In 1950, a Dutch Optician, Zacharias Janssen invented microscope. This instrument played an important role in later discoveries concerning Medicine. William Harvey made his discoveries on Blood Circulatory System were laying foundations to Systematic Physiology in 1628 A.D. A Dutch Naturalist, Anton Van Leevanhoek, carried out this observation.

In India, compared to the rule of Delhi Sultanate, Mughul administration was able to provide the country a much-desired political stability. Some of Moghul kings were favourable to Indian civilization; of them Akbar was highly compassionate to Indian values and was keen to rule the country, by winning the heart of Indian natives. Akbar’s main contribution for Ayurveda came from two corners. Firstly, he constructed a unique hospital where both Ayurvedic and Unani systems worked hand in hand. Secondly, his named remained in the history of Ayurveda immortal because of Todarmal – who was a scholar laureate in his court. 

Ayurvedic Texts During Mediaeval Periods

Coping up with all these negative influences, medical literature in India had attained a definite stride during mediaeval periods. Also the periods have witnessed a major level of enrichment of Ayurvedic literature prevailing at that time. This enrichment had two distinctly different directions -

Original Texts :- 

Various scholars through out the mediaeval periods authored a substantial number of new Ayurvedic books. Some of that are – 

1. Madhava Nidana written by Madhavakara in the field of Clinical Pathology.
2. Sarngadhar Samhita written by Sarngadhara in the field of Pharmaceutics.
3. Bhavaprakasha Nighantu written by Bhavamisra in field of Lexicon of Med. Plants 
4. Kalyanakaraka written by Ugradityacharya in the field of General Text.
5. Siddhasara Samhita written by Ravi Gupta in the field of General Text.
6. Dravyaguna Sangraha written by chakrapani Datta in field of Lexicon of Med. Plants
7. Anjana Nidana written by Agnivesa in the field of Clinical Pathology.
8. Vangasena written by Vangasena in the field of Therapeutics.
9. Brindamadhava written by Brinda in the field of Internal Medicine.
10. Parahita Samhita written by Srinatha in the field of General Text. 

From the above texts, three texts need a specific mention. Madhava Nidana (700 AD), Sarngadhara Samhita (13th Century) and Bhavaprakasha (16th Century) were distinctive in their nature as well as the contents. Thus, these three books are considered as Laghuttrayee (the minor triad).

Commentaries :-

Commentaries are referred to as " Vyakhya Vangmaya" . Commentaries were aimed to inherent brilliance of codified (sutra) language used in the ancient Ayurvedic literature. Every Sutra used in ancient Ayurvedic literature was designed precisely, to convey a distinct and elaborate information related to topic under discussion. Each of Sutra was strand like structure arranged in a coil design, which becomes obvious only, when the strands are separated and the coils are opened methodically.

Thus, commentaries on ancient Samhitas were an inevitable necessity. This literature was precisely aimed to segregate the strands and open-up coils of each Sutra, used in particular Samhita. More than 50 commentaries could be traced partially or fully, which were compiled during the mediaeval periods. Some of them are –

1. Nirantara Padavyakhya written by Jejjata on Charaka Samhita.
2. Kimvandanti written by Jejjata on Ashtangahridaya. 
3. Ayurveda Deepika written by Chakrapani Datta on Charaka Samhita.
4. Nibandha sangraha written by Dalhana on Sushruta Samhita.
5. Madhukosha Vyakhya written by Vijaya rakshita on Madhava Nidan.
6. Sarvanga Sundra written by Aruna data on Ashtangahridaya.
7. Shashilekha Vyakhya written by Indu on Ashtanga Sangraha.
8. Ayurveda Rasayan written by Hemadri on Ashtangahridaya. 
9. Deepika written by Adhamalla on S’arangadhar Samhita.
10. Ratna Prabha written by Nischalkar on Chakra Datta.

 

Modern Era: -

Under this head there are two categories: - 

1. Developmental Status Of Ayurveda
  Mughul dynasty was in power, for a total span of about 150 years. By the end of 16th century, the Allopathic Doctors hailing from Portugal, Dutch (The Netherlands), France and England were spread in important cities.

Overpowering others, Britain established its rule by 1765 A.D. through its East India Company. By this time, a number of western scholars were attracted to the richness of Indian art, culture and sciences. They were actively persuading their Indian studies with high academic spirits. As a result of this enthusiasm, William Jones established Asiatic Society in Calcutta, in 1754. Indian & European scholars, who became members of Asiatic Society to attract the attention of western scholars towards Indian Culture, Civilization, Arts and Sciences. 

In 1822 Government started the National Medical Institution at Calcutta headed by Dr. Tytler. During 1824, a Sanskrit College was also started at Calcutta for imparting education in both Oriental & upcoming western systems concurrently. In 1827 a medical course was started in Sanskrit College and the curriculam had both Ayurveda & Allopathy system. Pandit Madhusudan headed the faculty of Ayurveda. 

Parallel to Allopathic Medical Colleges, Vernaculer Medical Colleges were also started from 1835 onwards. Qualified in these Vernacular Medical Institutes were referred to as Native Doctors. Over a period of time Vernacular Medical Institutes were also converted into Allopathic Medical Colleges. Ayurvedic education went back to Guru – Shishya Parampara.

In 1885 the Indian National Congress was started. A feeling of Nationalism started creeping into all walks of life. In 1908, the All India Ayurvedic Congress was started, with a view to preserve & propagates the values of the great scientific heritage of the Nation. The most important task, the congress took up was re-organize the Ayurvedic education which was taken-up & was ignored more on political considerations. The first Ayurvedic College to be started under the aegis of Congress at Ahmed Nagaer in 1916.

Meanwhile, another endeavour to integrate Allopathic Medicine with Ayurveda –in common cause of Public Health was taken up in 1910 by the effort of Dr. Pardie Leucas, Director of medical services in the Imperior Government. As a result of his effort, the Govt. School Of Indian Medicine came in existence in 1925. In this system a student of Ayurveda was bound to know the development of Allopathy to enrich his professional skills.

Research in Ayurveda also, had attained a new dimension –by the studies conducted by Dr. Dwarkanath, at faculty of Medicine, Hamburg University Germany in 1935-37. The study evaluated Ayurvedic Gold preparations in Tuberculosis. He was first to demonstrate that, Gold processed as prescribed by Ayurveda is absorbed and metabolized by the body.

Sulpha drugs began the history of human success over infecting micro-organisms. While Domagk was busy in screening Sulfur compounds to fight infections, it was a chance discovery by Alexander Fleming in 1928 the Penicillin came into picture. This wonder substance could see the light as a drug in 1940 due to the efforts of Florey, Chain & Abraham. 

 

2. Present Status Of Ayurveda
  India acquired independence from British rule in 1947 and become a Democratic Republic in 1950. Developments of Ayurveda in India after independence need to focus on various aspects-
  a) Ayurvedic Education 
    The integrated approach of Ayurvedic Education started by efforts of Dr. Leucas continued for about one more decade. The parallel Institutions started by All India Ayurvedic Congress were running concurrently. Apart from these two institutions of learning one more institution working silently, without any kind of hindrances was, the Guru Shishya Parampara. 

Based on experience of multifacetated pressure, it was decided to bring the Ayurvedic education under the preview of universities in Independent India. By 1969 all the colleges imparting education in Ayurveda or other Indigenous system of medicine –were affiliated to respective universities. In 1970, the Central Council Of Indian Medicine was constituted through an enactment in the Parliament. The council works for maintenance & up-gradation of standards of education in Ayurveda.

Besides Graduate and Post-Graduate courses, different levels of training are being imparted for Para-Medical staff, like Panchkarma Technicians, Ayurvedic Pharmacist etc. at different centers in India.


Now there are few institutions of national repute, which are conducting various programs in the field of Ayurveda, viz. Faculty of Ayurveda, Institute of medical Sciences Banaras Hindu University, Varanasi, Institute of Post Graduate Training & Research, Gujrat Ayurveda University, Jam Nagar, National Institute of Ayurveda, Jaipur & Rashtriya Ayurved Vidyapeetha, India.
  b) Patient Care Services
    A number of Hospitals, Dispensaries run by Government, Local Administration provide treatment to the needy, employing Ayurvedic methods. 
  c) Research In Ayurveda
    Research in Ayurveda with clearly defined objectives and well-designed protocols is the need of hour- if Ayurveda has to respond to emerging challenges of the global health care scenario. Realizing this need a number of organization were pressed into various aspects of these research needs. 

A deliberate effort to carry out integrated and coordinated research on medicinal plants selected after careful discussion and consultation with reputed Ayurvedic & Unani physicians was made for the first time in India by the Indian Council of Medical Research (ICMR) in 1964 through the Composite Drug Research Scheme (CDRS). In 1970, this scheme was transferred to the newly constituted Central Council For Research In Indian Medicine & Homeopathy (CCRIMH). Recently, two autonomous bodies, the Council For Research In Ayurveda And Siddha and Central Council For Research In Unani have been constituted after winding up the CCRIMH. 

The Institute of Medical Sciences at Banaras Hindu University and Gujrat Ayurved University has taken up interdisciplinary research in Ayurveda on a large scale, among both curricular and co-curricular programmes. 

Research efforts in Ayurveda have increased manifold during the last couple of decades. However, most of these efforts have revolved around the intention of discovering new drugs from plants. Many drugs obtained from plants, which have carved out an important place in modern medicine for themselves as-

  d) Manufacturing of Ayurvedic Medicine
    In 1964, manufacturing of Ayurvedic Medicine was brought under the scope of Drugs & Cosmetics Act, through an amendment enacted by the parliament. As a result, the government could exercise appropriated regulation over the manufacturing of Ayurvedic Medicine. This regulation helped the Industry of Ayurvedic Medicines to grow in a healthy environment. 

The GMP (Good Manufacturing Practice) certification also played an important role to provide, quality standard as per the norms of World Health Organization in the field of Ayurveda Industries. Recently Govt. of India has laid down separate GMP requirements for Ayurvedic manufactures & made it mandatory.
  e) Cultivation of Medicinal Plants 
    Ayurveda advocated a harmonious interface of human beings with nature as; it recognizes him to be an integral part of Universe. Also, Ayurveda draws its therapeutic agents mainly, from Plant Kingdom. Thus, the forests have been the conventional sources of Ayurvedic Medicines. However, under threatened ecological balance and dwindling forest resources, Ayurveda as a whole-faces a major threat in near future.

So, more precise methods for propagation of Medicinal Plants should be devised through methodical research. Tropical Botanical Garden & Research Institute (TBGRI), and Centre for Indian Medical Heritage (CIMH) promoted by Ayurvedic Trust –are working in this direction besides many other agencies in the country.
