What Is Boerhavia Diffusa Root Extract?
Boerhavia diffusa root extract comes from the plant family Nyctaginaceae. While the plant itself has a long history of use in ayurvedic practices and traditional medicine, less has been known about its proven topical benefits for skin until more recent years. Of note, studies show the root extract possesses skin-soothing properties and antioxidant capabilities.
Boervavinone B, a component of Boerhaavia diffusa root extract, also shows promise for correcting the look of skin discolorations (i.e. hyperpigmentation and dark spots) for a more uniform complexion. To achieve this benefit, it is recommended that Boerhaavia diffusa root extract be used in 1-3% concentration. Other potentially beneficial compounds of Boerhavia diffusa root extract include its amino acids (alanine, arginine, aspartic acid, glutamic acid, proline, serine, and glycine just to name a few) which help contribute to skin's natural moisturizing factor (NMF), key to balanced hydration.
While official research on Boerhavia diffusa root extract's safety as a cosmetic ingredient is lacking, its track record of research for safe oral administration is a good sign.
Note: Boerhavia diffusa also goes by the spelling of Boerhaavia diffusa. It is sometimes referred to by its Sanskrit name of "punarnava". The plant can be found in the tropics and subtropics but is native to India. The roots of Boerhavia diffusa are woody, with a pale yellow to brown color.
