Sapta Dhatu in Ayurveda (Seven Types of Tissues)

The structural and supporting units of the body are called Dhatu in Ayurveda. In modern science, it related to tissues. So, Dhatu meaning in English is tissue. In ayurveda science, there are seven basic tissues that make the body and these tissues are collectively called Sapta Dhatu in Ayurveda.

Rasa DhatuBody fluids
Rakta DhatuBlood
Mamsa DhatuMuscular tissue
Meda DhatuAdipose tissue
Asthi DhatuBony tissue
Majja DhatuBone marrow and nervous tissue
Shukra DhatuGenerative tissue (including semen and ovum constituents, stem cells)

Dhatu Agni

According to Ayurvedic Principles, each Dhatu has its own specific Agni. This is called Dhatu-Agni. This Agni relates to specific enzymes, chemicals and processes in the body that help to convert Dhatu to higher Dhatu or Upadhatu (sub-tissue or secondary tissue). These metabolic processes also give rise to waste products, which are called Mala in Ayurveda. These include nail, hairs, saliva, tear, ear wax, stool, urine, sweat etc.

Precursor of Sapta Dhatu

The food is the precursor of all tissues. The waste products of food are stool and urine.

  3. Obese people have weak bones and more prone to fractures. It represents they have weak Dhatu Agni that does not process Medha Dhatu into Asthi Dhatu. Which medicines or specific herbs can improve this Agni?

    1. Absolutely, you are right. Medicines will remain the same which improve overall digestive power, liver function, and Agni. For example, Trikatu churna will do the job. In addition to Trikatu Churna, you also require anti-obesity herbs including Vacha, Pushkarmool, Kutki, Nagarmotha, Chitrak, Triphala etc. All these herbs also improve Dhatu Agni. Therefore, they reduce weight and improve bone density. However, the patient may also require supportive treatment for weak bones, especially if he is prone to osteoporosis. Hadjod, Arjuna, Godanti Bhasma and other natural calcium compounds can help in the treatment of weak bones.
