The five elements are: Earth (sa, Skt. pṛthivī, bhūmi), Water (chu; Skt. jala, āpa), Fire (me; Skt. teja, agni), Air or Wind (rlung; Skt. vāyu), Space (nam mkha’; Skt. ākāśa).
Doctrine of primary elements is the essential foundation of Tibetan Medicine Sowa Rigpa, (gso ba rig pa). According this doctrine five primary elements are the basis of all phenomena, both objective and subjective. In particular, they correlate with the various organs and tissues of the body, as well as the processes occurring in the body.
Qualities of the Earth primary element appear in the solid tissues of the body - muscles, bones, etc., of the the sense organs - the nose and sense of smell. Furthermore, the influence of this primary element connected with the fact that the human body has a shape, weight, density, etc.
Qualities of the Water primary element appear in the blood and other body fluids, among the sense organs it is the tongue, as well as sense of taste. Under the influence of this primary element the body is not divided into separate parts, but functions as a whole.
Qualities of Fire primary element are manifested in body temperature, color of organs and tissues, and among of the senses and their organs eyes and vision. Under the influence of this primary element it matures, i.e. maintenance of all systems and processes in the body at an optimum level.
Qualities of the Air primary element manifest in the respiratory system and all its functions. Among sense organ it is the skin, as well as sense of touch. Under the influence of this primary element growth and development occurs in whole body and its parts.
Finally, the qualities of the Space primary element manifest in the existence of internal and external openings and cavities. Among sense organ it is the ears, as well as sense of hearing. The effect of this primary element is the very possibility of the existence of things and phenomena.
The five primary elements form three nyepa (nyes pa) and their 17 qualities. This doctrine of primary elements pervades the pharmacology of Tibetan medicine: the origin and properties of the six tastes, 20 characteristics of medicines, etc.
