Ayurveda is an ancient Indian system of medicine that focuses on prevention, longevity and overall well-being. It believes that health and disease are primarily determined by three doshas or biological energies (vata, pitta, kapha) and advocates lifestyle modifications, herbal remedies, yoga and panchakarma therapies to achieve balance. Some key aspects covered are the major Ayurvedic scholars like Charaka and Sushruta, the panchamahabhootas that constitute the doshas, factors influencing health like diet, lifestyle and sleep, seasonal routines, panchakarma cleansing therapies and the holistic nature of Ayurveda treatment.
