Medo dhatu or fat tissue is one among the 7 dhatus (tissues) explained in Ayurveda. It is the 4th tissue in the sequence and is formed from Mamsa dhatu or muscle tissue. Medo dhatu is the precursor of Asthi dhatu or bone tissue.
When the Mamsa dhatwagni (tissue fire of muscle tissue) acts on the poshaka mamsa (nutrients of muscle tissue which form the fat tissue), the meda dhatu or fat tissue is formed. For this to happen, the Mamsa dhatu agni should be in a balanced state.
The Meda dhatu or fat tissue thus formed is further subjected to metabolism by Medo dhatu agni or tissue fire of fat tissue. This leads to the formation of poshya meda dhatu or fat tissue which nourishes the local fat tissue and enriches it. The other part becomes Poshaka medo dhatu i.e. the part of medo dhatu which further forms asthi dhatu or bone tissue. During this metabolism of fat tissue heat and wastes are also formed. The waste is generated in the form of sweat.
If the medo dhatwagni is balanced, the fat is formed in normal quantity and in best quality. This type of meda or fat tissue helps in protecting the body and participates in the lepana karma i.e. insulating and protecting the tissues and organs.
