Ayurveda is a comprehensive system of healthcare originating in India over 5,000 years ago. Ayurveda is derived from two Sanskrit words: 'Ayus' meaning life and 'Vid' meaning knowledge.
Classical Ayurvedic texts such as the Charaka Samhita and the Sushruta Samhita, compiled between the second century BCE and the second century CE, took account of the physical, mental, emotional and spiritual aspects of the person in their consideration of health and ill-health.
The Universe according to Ayurveda is composed of five basic elements or pacha mahabhuta, namely, ether, air, fire, water and earth. These are present in all things and in the human body they are represented as the doshas, dhatus and mala.
Dosha is an Ayurvedic term that generally describes our inherited traits, individual characteristics and tendencies such as the body frame, eye colour, digestive capacity and emotional balance. Everybody has different levels of doshas. The Constitution is set at birth but some traits may accumulate. If the accumulation does not leave the body in the usual way, for example, stools, urine or sweat, it increases. According to Ayurveda, this is the cause of most disease. If the doshas are cared for properly they will offer great potential for health and vitality.
Doshas are not visible. You will only know through inference as they manifest through the products of disease such as phlegm, swellings, inflammation, bleeding, nervous imbalances and dry skin. You would not see these symptoms if you were in perfect health.
