Mansa Dhatu (मांस धातु)
Mansa dhatu (मांस धातु) is the 3rd dhatu in order of 7 dhatus described in Ayurveda. It is that structural unit or body tissue which performs the important function of covering and protection of body. The word 'Mansa' literally means flesh or meat. Thus, Mansa dhatu is fleshy body tissue which makes it equivalent to muscle tissue identified by western medicine.
Etymology
The word 'Mansa' is derived from Sanskrit root called “Mans” meaning flesh or meat. Flesh in the body of any animal is present as a covering to main skeleton or bones. It takes part in the process of movements and protects the delicate structures inside the body by providing firm covering. Thus, Mansa dhatu is the component in humans, which covers body parts, takes part in movements of joints of bones and enhances body mass.
Synonyms
Mansa dhatu is mentioned at various places in the treatises by various different synonyms. Pishita, Kravya, Palala and Amisha are some of the synonyms for mansa dhatu used in Ayurveda literature. Synonyms are used at places to specifically highlight mansa dhatus peculiar function in that context.
Formation of Mansa Dhatu
The mansa dhatu is formed from its predecessor rakta dhatu. When Rakta dhatu is subjected to the process of micro-transformation (सूक्ष्मपचनम्), one processed part of it is specifically utilized to provide nourishment to the next dhatu in order i.e. Mansa Dhatu (धातु). This part is responsible for development and nourishment of mansa dhatu in body. Transformation of this fluid part of rakta into solid form mansa happens due to action of vayu, jalam and tejas mahabhutas. [Cha. Sa. Chikitsa Sthana 15/29]
Location of mansa dhatu
Mansa dhatu is solid in nature. It covers the body and protects inner organs. The chief sites of Mansavaha srotas (channel of transportation and metabolism) are snayu ( ligaments, muscles) and twak ( skin). Thus, Mansa dhatu lies in snayu and twak in abundance.
Panchabhoutik constitution
Mansa dhatu is developed from Rakta dhatu which displays presence of all 5 mahabhutas equally. Thus Mansa dhatu also possesses all 5 mahabhutas in it. However, since it is solid in nature it shows abundance of prthvi mahabhuta.
Function
The chief function of mansa dhatu is to provide covering and protection of inner organs from external and environmental factors. This function is referred as lepanam by Acharya Vagbhata.
लेपः-उपदेहो, मांसस्य कर्म| तदुपलिप्तान्यस्थीनि चेष्टां क्षमन्ते| [1]
Covering and protection (Lepana) is the main function of mamsa dhatu. . It provides support for various movements and protection to the inner organs too.
..मांसं शरीरपुष्टिं मेदसश्च..[2]
Providing strength to the body and nourishment to its successor adipose tissue (meda dhatu) are additional functions. [Su. Sa. Sutra Sthana 15/5].
Mamsa dhatu is also inevitably involved in sustaining the strength of the body (bala)
Upadhatu of mansa dhatu
Vasa ( muscle fat ) and Tvacha ( skin) are known to be the metabolic byproducts of Mansa dhatu metabolism. Thus, these are known as upadhatus of mansa dhatu.[3]
Skin, which is considered to be the largest organ of human body, is known as tvak or tvacha in Ayurveda and it is directly associated with Mansa dhatu. Therefore mansa dhatu metabolism plays significant role in maintaining the health of skin.
Mala of Mansa dhatu
According to Ayurveda, there are some external orifices in the body which regulate the exchange of substances between body and outer environment. Nasal cavity, oral cavity are some of them. In all such external orifices various secretions are accumulated. These secretions which in optimum amount perform the function of protecting the inner skin of these orifices are believed to be the waste by-products of mansa dhatu metabolism. These are known as kha-malas (kha-cavity, malas-wastes). Kha-malas are thus malas of mansa dhatu.[4]

The persons having essence of mamsa dhatu have their temples (shankha), forehead (lalata), nape (krikatika), eyes (akshi), cheek (ganda), jaws (hanu), neck (griva), shoulder (skandha), abdomen (udara), axillae (kaksha), chest (vaksha), hands (pani), feet (pada) and joints (sandhi) well developed with firm, heavy and good looking muscles. This essence indicates forbearance, restraint, and lack of greed, wealth, knowledge, happiness, simplicity, health, strength and longevity. [Cha.Sa. Vimana Sthana 8/105]
Vitiating factors
The following are causative factors for the vitiation of channels for transport and transformation of mamsa dhatu (mamsavaha srotasa). [Cha. Sa. Vimana Sthana 5/15]
Dietary causes
- Excessive consumption of food that increases secretions and causes obstruction (abhishyandi), bulkiness, heaviness after digestion
Lifestyle causes
- Day time sleep
Importance of Mansa dhatu in health and wellbeing
- Proper musculature (samshanana) is one of the assessment parameters of health. Physical strength directly depends upon musculature.[Cha.Sa.Vimana Sthana 8/116]
- A person with a balanced proportion of muscles and compactness of the body and firmness in sense organs is not affected by diseases. Such people can tolerate hunger, thirst, the heat of the sun, cold and physical exercise. Their digestion, assimilation of food, and muscle metabolism are in a state of equilibrium. [Cha. Sa. Sutra Sthana 21/19].
- The qualitative and quantitative decrease in mamsa dhatu is directly related to diminution of strength (bala kshaya) [Su. Sa. Sutra Sthana 28/20] and vitality (oja kshaya)[Su. Sa. Sutra Sthana 15/24]. Thus, the nutrition of mamsa dhatu is related to strength and immunity of a person.
