A Beginner’s Guide to the Meda Dhatu

Meda dhatu is the fourth dhatu after the mamsa dhatu in the sequence. It mainly does oleation or anointing of the structures of the body like Twak (skin), Akshi (eyes), Kesha (scalp hair), Loma (body hair), Nakha (nails), Danta (teeth), Oshta (lips), Mutra (urine) and Shakrut (feces). The word ‘Meda’ originated from the Sanskrit language which means oleation or anointing. The synonyms are Mamsatejasa, Asthikrit, Vasa, Vapa, Gautam, Goda, Mamsaja. It is unctuous just like that of ghee.

Bhautika composition and its guna (qualities)

There are different views regarding the composition of Mahabhuta. Acharya Charaka says it is made up of only Jala Mahabhuta. Sushrutha opines that it is composed of Jala and Prithvi Mahabhuta while Vagbhata mentions Jala, Prithvi, and Agni Mahabhuta are responsible for constituting Meda dhatu.

Sthira (stability), Snigdha (unctuous), Sandra (compactness), Guru (heaviness), and Mrudu (soft) are the qualities of Meda Dhatu.

Formation of meda dhatu

The Medo Dhatwagni acts upon the Medo Dhatu which gets divided into two components, one is the poshya amsha and the other is the poshaka amsha. The poshya amsha nourishes the medo dhatu, and after the metabolism, the upadhatu (byproducts) and the mala (waste products) are formed. The other portion is that poshaka amsha provides the nutrients to the asthi dhatu.

Seat of Meda dhatu

There have been different opinions with respect to the main origins and the site where the formation of meda dhatu takes place. Charaka says Vrikka (kidneys) and Vapavahana (omentum), and Sushrutha quotes Vrikka (kidneys) and Kati pradesha (pelvic region). Vagbhata mentions the places as Vrikka (kidneys) and Mamsa dhatu (muscle tissue).

Quantity and duration taken to form meda dhatu

Two Anjali is the total quantity of meda dhatu present in the body. It is told in the Ayurveda texts that the time taken for the formation of meda dhatu is 9045 kala i.e. fifteen days.

Byproducts and the waste metabolites

Snayu (ligaments) and Sandhi (joints) are the byproducts of upadhatu and the sweda (sweat) and kleda (sebum) is its waste product.

Functions of meda dhatu
