Zuo gui wan is an ancestral formula that was developed by traditional Chinese medicine to strengthen Yin in order to restore energy balance and allow the return of sexual well-being.

Indeed, Zuo gui wan is reputed to nourish Yin in order to balance an overly predominant Yang of the Kidneys. Thus, Zuo gui wan slows down the signs of aging and effectively soothes localized sensitivities in the lower back. Moreover, since the Kidneys are in charge of the sexual and reproductive functions in TCM, the harmony of these energies promotes the sexual vitality of the man and puts an end to potential disorders.
