Every second 50 million new body cells have to be produced in the human body. Why? Because so many “old” ones need to be replaced. The conditions in the gastrointestinal tract should work in such a way that a liquid “Rasa-Dhatu” is created from the basic substance Ahara Rasa. Dhatus are body tissues.

From the perspective of Ayurveda, the different body tissues develop as part of the tissue's own metabolic process. One tissue emerges from the other! The 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 on the one hand it transports doshas to their destination, but on the other hand it also transports dissolved doshas and toxins out of the body. Therefore, Rasa-Dhatu is essential in the Panchakarma cure, which aims to cleanse the body of toxins and regain the Prakriti (basic constitution).

Rasa-Dhatu (blood plasma and lymph) then creates blood (Rakta-Dhatu), then it becomes muscle (Mamsa-Dhatu). Then fat is created (Meda-Dhatu), from which bone (Asthi-Dhatu) and from it bone marrow (Majja-Dhatu). Then the circle closes, because the male and female reproductive tissue arises from Maija-Dhatu (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, breaks down (as mentioned above) the food into its individual elements and transforms these nutrients in the process of conversion into tissue.

The properties of Agni are different in each person. Therefore, every person has different eating habits, which depend on their individual appetite, and may have completely different problems, such as obesity, low energy or even diseases of the digestive organs.
