Every second in the human body 50 million new body cells produced Why? Because so many “old” ones have to be replaced. The conditions in the gastrointestinal tract should work in such a way that the basic substance Ahara Rasa a liquid "Rasa-Dhatu“ is created. Dhatus are body tissues.
From the perspective of Ayurveda, the different body tissues develop as part of a tissue-specific metabolic process. One tissue emerges from the other! Rasa Dhatu is the first body tissue that refreshes and nourishes all cells and organs.
Rasa-Dhatu contains all three doshas. Rasa-Dhatu is the “transport company of the body” because it transports doshas to their destination and also flushes dissolved doshas and toxins out of the body. Therefore, Rasa-Dhatu is essential in the Panchakarma treatment, which aims to cleanse the body of toxins and regain Prakriti (basic constitution).
Rasa-Dhatu (blood plasma and lymph) then produces blood (Rakta-Dhatu), then it becomes muscle (Mamsa- Dhatu). Then fat is created (Meda-Dhatu), from which bones (Asthi-Dhatu) and from this bone marrow (Majja-Dhatu). Then the circle closes, because from Maija-Dhatu the male and female reproductive tissues arise (Shukra/ Artava).
The prerequisite for all life functions - the function of metabolism - all cell-renewing functions is the digestive fire "Agni". Agni controls the breakdown of food into usable nutrients and waste products, splits the food into its individual elements (as mentioned above) and transforms these nutrients in the process of conversion into tissue.
The properties of Agni vary from person to person. Therefore, each person has different eating habits, which depend on their individual appetite, and may have completely different problems, such as being overweight, having little energy or even having digestive diseases.
