Ayurveda is a science of life with a holistic approach to health and personalized medicine. It is known to be a complete medical system that comprised physical, psychological, philosophical, ethical, and spiritual health.
In Ayurveda, however the success of Chikitsa depends mainly upon four factors which are known as Chikitsa Chatushpada. These Chatushpada includes Bhishag, Upastha, Rogi and Dravya.
The success of any physician depends on good quality of drugs. Hence no matter how perfect a physician is in diagnosing and treating any disorder but he is helpless without good quality and effective medicines.
Acharya Charak said that Aushodhi is not only “drug”, but any kind of substance, which is useful in the management of disease is called as drug.
The selection of the proper drug in the management of disease is very important.
