===Formation===

Oja is present in dormant form in sperms (shukra) and ovum (shonita) of parents. [Dallhana Commentary on Su. Sa. Sutra Sthana 15/9].  After conception, it is manifested as the first body component in intra-uterine life. [Cha.Sa. Sutra Sthana 17/75] It is termed as the basic constituent of embryo (garbha sara) and resembles with morula stage (kalala). The embryo is nourished from this essence component. [Cha.Sa. Sutra Sthana 20/9-11] Further it is nourished and developed during gestation.

[[Sutra Sthana]] 20/9-11] Further it is nourished and developed during gestation.  

After birth, Oja is formed as essence during the metabolism of each [[dhatu]]. [Su.Sa. Sutra Sthana 15/19], [A. Sa. Sharira Sthana 6] It is the unctuous component of each [[dhatu]] having its purest form and supreme quality. [Su. Sa. Sutra Sthana 15/19]

Some scholars opine that it is the essence of reproductive tissues (sara of [[shukra dhatu]]). [A. Sa. Sharira Sthana 6/29]. Sharangadhara considers it as a metabolic by-product (upadhatu) of reproductive tissues (shukra). [Sharangadhara Samhita Purva Khanda – 5/17]. Vagbhata opines that it is a metabolic waste product of reproductive components ([[shukra dhatu]]). [A.Hr. Sharira Sthana 3/63]

===Measures for the preservation of Oja and treatment of its disorders===

The treatment measures of pacification of vata and pitta dosha and enhancement of kapha dosha are applied to preserve the quality of Oja and treatment of its disorders. The diet and lifestyle regimen having similar properties as Oja is prescribed in treatment. Rejuvenation therapies (rasayana) and aphrodisiac therapies (vajikarana) are two major treatments. Dietary items like ghee [Cha.Sa. Sutra Sthana 13/14] and cow milk [Cha.Sa. Sutra Sthana 27/217] are beneficial for enhancing Oja. Ghee, milk, and meat soup processed with herbs enhancing vitality (jeevaniya) [A.Hr. Sutra Sthana 11/41] is prescribed for the treatment of Oja.

The disorders of Oja are treated with the herbs with immunomodulatory activity like Ashwagandha (Withania somnifera), Shilajatu, Amalaki (Emblica officinalis), Tulasi (Ocimun sanctum), Guduchi (Tinospora cordifolia), Pippali (Piper longum), and Punarnava (Boerhaavia diffusa).<ref> Tripathi J.S., Singh R.H.

Anc Sci Life. 1999;19:59–63.</ref> The rejuvenation potency of herbs is studied in view of free radical scavenging activity as anti-oxidant. The herbs like Rubia cordifolia, Strychnos nuxvomica, Moringa oleifera, Semecarpus anacardium, Mucuna pruriens, Bacopa monnieri, Nardostachys jatamansi showed good efficacy as anti-oxidants.<ref>Tripathi YB.

A research study on the effect of Terminalia arjuna on Oja kshaya showed cardioprotective herbs (hridya) medicines might have an effect on enhancing Oja. Lifestyle also plays a significant role in the conditions of Oja.<ref>Santosh Mane (2004).Study on Sangraha Dwaya of Charaka and assessment of the effect of Hridya Aushadhi on Oja-Kshaya.
