Asthi Dhatu (Bone) is the bones structure or skeleton. It provides support to all
other tissues and body structure. It also maintains the teeth, the hair and nails.
It has earth and air as leading elements.
In the physical body, asthi dhatu is formed as posaka (unstable) medas dhatu flows
into the purisha dhara kala and is digested by the asthiagni. In addition to the
formation of the bones of the body, teeth are formed through this process and are
thus the upadhatu (secondary tissue) of the production of asthi dhatu. Ch. Chi.
The purisha dhara kala is the membrane that holds the asthi agni. Purisha means
“feces”. The term is also used to describe the large intestine as in the purishavaha
srota. Here lies an important clue of the relationship between health of the large
intestine and that of the bones. The large intestine is the home site of vata dosha.
The close relationship between these two tissues reveals the susceptibility of the
bones to vata disorders. When there is pathology in the large intestine (gas, constipation)
the pathology is transferred to the bones which become more porous and air filled.
Such is the case of osteoporosis.

According to texts of ayurveda asthis or bones are formed from the nutrients supplied
by medha dhatu through asthivaha srothas. The nutrients in medho dhatu which is
meant to nourish asthi dhatu are processed in asthivaha srothas by dhatwagnis. Dhatwagni
and bhutagni (vayu, agneya and prithvi) bring about hardness and heaviness to these
nutrients which form asthi or bone. Su. S. 15/5
