These remarks appear obvious today, though they were often not heeded, and were made by Charak, in his famous Ayurvedic treatise Charak Samhita. The treatise contains many such remarks which are held in reverence even today. Some of them are in the fields of physiology, etiology and embryology.
In the “Charak Samhita” he has described the medicinal qualities and functions of 100,000 herbal plants. He has emphasized the influence of diet and activity on mind and body. He has proved the correlation of spirituality and physical health contributed greatly to diagnostic and curative sciences. He has also prescribed and ethical charter for medical practitioners two centuries prior to the Hippocratic oath. Through his genius and intuition, Acharya Charak made landmark contributions to Ayurvedal. He forever remains etched in the annals of history as one of the greatest and noblest of rishi-scientists.
Under the guidance of the ancient physician Atreya, Agnivesa had written an encyclopedic treatise in the eighth century B.C. However, it was only when Charaka revised this treatise that it gained popularity and came to be known as Charakasamhita. For two millennia it remained a standard work on the subject and was translated into many foreign languages, including Arabic and Latin.
