REVISIT TO CONCEPT OF DHATU FORMATION
A shloka given in Charaka1, Sushruta2 and Ashtanga hridaya3 is translated and interpreted in such a way that it seems that rakta is formed by rasa, mÄmsa by rakta, medas by mÄmsa, asthi by medas, majjÄ by asthi and shukra by majjÄ and this occurs by sukshma amsha of the preceding dhÄtu transforming into the succeeding dhÄtu. But review of the pertinent literature in this article reveals that this translation and interpretation seems to require major correction as Charaka and Sushruta clearly opine that all the dhÄtu are formed separately by taking its dhÄtvÄhÄra present in the ÄhÄra-rasa (essence of food). DhÄtvÄhÄra means specific nutrient material required by a particular dhatu for its nourishment or development. It is further explained that vyÄna vÄta circulates ÄhÄrarasa all over the body and it reaches to all the dhÄtu simultaneously. The specific dhÄtvÄhara of each dhÄtu stays for 5 days more in respective succeeding dhÄtu during which it is converted to that dhÄtu by acting upon by respective dhÄtvÄgni. It implicates that from dhÄtvÄhara obtained from ÄhÄrarasa, the rasa is formed immediately, rakta is formed in 5 days; mÄmsa is formed in 10 days, medas in 15 days, asthi in 20 days, majjÄ in 25 days and shukra is formed in 30 days.Â Further the translation of â€˜DhÄtavo hi dhÄtvÄhÄrÄhâ€™ as per Chakrapani is that continuously depleting dhÄtu remain normal by taking specific dhÄtvÄhara present in ÄhÄra-rasa and not that dhÄtui is food (ÄhÄrÄ) of the dhÄtu.
