Native to Asia and Oceania, Oxyphylla is a plant that grows in tropical climates and is recognizable by its clustered flowers with white petals.The seeds of Oxyphylla (or Yi zhi ren in Chinese) help to regulate the urinary flow and anticipate the aging of the prostate.

In TCM, Yi zhi ren essentially reinforces the kidneys and protects the essence (Jing) which they host. This action on the Jing and the kidneys helps to soothe the prostate swelling. Thus, Yi zhi ren relieves prostate problems and enables to return to a healthy and regular urination. It is considered a true ally to regain male comfort.
