Definition - What does Rasa Dhatu mean?
According to Ayurveda, the Sarira (body), Manas (mind), and Prana (life force) are all supported by tissues known as dhatu. Rasa Dhatu is the first of seven tissues, and is comprised of plasma, lymph and white blood cells. Rasa Dhatu may also refer to watery secretions such as breast milk and menstrual fluid.
In Sanskrit the word Rasa means juice, sap or liquid. Although it is made up of the water element, Rasa Dhatu is understood to be more than just liquid. It is responsible for providing nutrients and energy to all other cells and tissues of the body, thereby creating a stable foundation for physical growth.
Yogapedia explains Rasa Dhatu
The relative balance of Rasa Dhatu is important in determining the health of Kapha dosha. Vata and PItta have the tendency to dry or burn out Rasa Dhatu. Rough or dry skin, constipation, dry mucous membranes and lack of breast milk are all indicators of depleted levels of Rasa Dhatu in the body. This may also cause dissatisfaction and restlessness in the mind.
Excess Rasa Dhatu can cause water retention, swelling and the formation of unnecessary mucous in the body. It may also increase the menstrual flow in women, leading to heavier and longer-lasting periods. Too much Rasa Dhatu can make the mind feel cloudy, foggy or sluggish.
A healthy balance of Rasa Dhatu depends on the quality and quantity of water intake. When it is in balance, drives such as compassion, love and desire are stable, and the vital functions of the body operate smoothly.
