Ayurveda is a science of life based on the concept of three Doshas known as Tridosha.In Ayurveda our body is believed to be made of five elements-Prithvi(earth),Jal(water),Agni(Fire),Akash(space) but its functions are governed by three biological humors known as tridosha.
The three Doshas described in Ayurveda are
1. Vata
2. Pitta
3. Kapha
According to Ayurveda all the functions of body are being governed by a balance of these three specific humors termed as “Tridosha”. Dosha means a fault which can easily go out of balance leading to a disorder in the body or mind.According to the philosphy of Ayurveda body and mind remain healthy only if doshas remain in balance, thus disease occurs only after imbalance of doshas.
