Ayurvedic concept of Ahara Rasa and Rasa Dhatu
Abstract
According to Ayurveda, food is the main pillar of healthy life. Living body is continuously subjected to wear and tear process. Dhatus which are being lost in physiological activities are replenished by food and water. Man needs to eat food to build a new Dhatus and to repair damage Dhatus. After consumption food is digested in gastro intestinal tract. Fluid formed from the digested part of food is called as Ahara-Rasa. For growth, Dhatus needs nourishment, and these Dhatus are nourished by food and water. Aahar Rasa is formed in Annavaha Srotas. Aahar Rasa contains nutrients of seven Dhatus. Aahar Rasa is absorbed from Grahani (small intestine) and brought into heart. Heart is a root of Rasavaha Srotas, hence in heart, Rasa Dhatvagni transforms nutrients of Ahara Rasa into stable Rasa Dhatu. Rasa Dhatu is formed in Rasavaha Srotas. Rasa is the first Dhatu formed from Aahar-Rasa.
