Effects of Ginsenoside Rb1 on Skin Changes.

Ginseng roots (Panax ginseng CA Meyer) have been used traditionally for the treatment, especially prevention, of various diseases in China, Korea, and Japan. Both experimental and clinical studies suggest ginseng roots to have pharmacological effects in patients with life-style-related diseases such as non-insulin-dependent diabeticmellitus, atherosclerosis, hyperlipidemia, and hypertension. The topical use of ginseng roots to treat skin complaints including atopic suppurative dermatitis, wounds, and inflammation is also described in ancient Chinese texts; however, there have been relatively few studies in this area. In the present paper, we describe introduce the biological and pharmacological effects of ginsenoside Rb₁ isolated from Red ginseng roots on skin damage caused by burn-wounds using male Balb/c mice (in vivo) and by ultraviolet B irradiation using male C57BL/6J and albino hairless (HR-1) mice (in vivo). Furthermore, to clarify the mechanisms behind these pharmacological actions, human primary keratinocytes and the human keratinocyte cell line HaCaT were used in experiments in vitro.
