The Sapta Dhatus (The Tissue Elements)
A body tissue is known in Ayurveda as the Dhatu. The meaning of the term Sapta is seven.
A tissue, in simple terms, is a bonding cord. It ties together the body parts and also the different parts with one another to constitute a comprehensive whole.
There are seven Dhatus – These are:
1. Rasa (or Chyle) : Includes the lymph;
2. Rakta : Encompasses blood (primarily the haemoglobin);
3. Mamsa : Includes the muscle tissues;
4. Meda : Refers to the fat tissues;
5. Asthi : Points to the bone marrow;
6. Shukra : Denotes sperms in males and ova in females.
