The word Ayurveda means science of life. It belongs to the Indian Roots. According to Ayurveda every life form has 3 doshas which are primarily responsible for our health as well as disease. When these doshas are in balance the person remains healthy i.e. Arogyata, but when these doshas get vitiated which leads to different diseases. So Ayurveda deals about keeping these doshas in their natural state and keeping one person healthy.
There are 8 components of Ayurveda which are collectively known as Astang Ayurveda.
