Abstract:
Recently, both clinical and bench research has begun to provide scientific validation for the use of certain botanical ingredients. Related findings regarding proposed biological mechanisms of action have translated into clinical practice. Botanical compounds for which dermatologic and cosmetic applications have emerged include: olive oil, chamomile, colloidal oatmeal, oat kernal extract, feverfew, acai berry, coffee berry, curcumin, green tea, pomegranate, licorice, paper mulberry, arbutin, and soy. Many of these botanical sources offer biologically active components that require further in vitro and in vivo investigation in order for us to properly educate ourselves, and our patients, regarding over-the-counter products based on these ingredients.
