Ayurveda states that our body is made up of the three doshas or vital energies. They are combinations of the five elements: ether (space), air, fire, water and earth. Vata is a combination of ether and air, Pitta is a combination of fire and water and Kapha is a combination of water and earth.These are called tridoshas and the entire ayurveda is based on these principles. Each of us is born with an individual constitution or prakruti, made up of the three doshas (five elements). Our prakruti is determined by our parent's doshas at the time of conception.

• Dhatus : These are the basic tissues which maintain and nourish the body. They are seven in number namely- rasa(chyle), raktha(blood), mamsa(muscles),meda(fatty tissue), asthi(bone), majja(marrow) and sukra(reprodutive tissue). Proper amount of each dhatu and their balanced function is very important for good health.Mala- These are the waste materials produced as a result of various metabolic activities in the body. They are mainly urine, feaces, sweat etc. Proper elimination of the malas is equally important for good health. Accumulations of malas cause many diseases in the body.
• Srotas: These are different types of channels which are responsible for transportation of food, dhatus, malas and doshas. Proper functioning of srotas is necessary for transporting different materials to the site of their requirement. Blockage of srotas causes many diseases.
• Agni: These are different types of enzymes responsible for digestion and transforming one dhatu to another.
