Acne is a relatively common disorder, especially in the adolescent or 20-30th young people. The condition is characterized by comedones, papules and pustules. Acne has social and psychological influence on the acne patients. But there is no perfect treatment of acne. It is known that Herba Houttuyniae has anti-inflammatory action and anti-bacterial action. Therefore, we studied the effect of 5% Herba Houttuyniae extract solution on the acne. The study was designed to compare the efficacy of 5% Herba Houttuyniae solution on the acne. The study was carried out on two groups-a experimental and a control group- for 4 weeks. Efficacy was determined by investigating counts of non-inflammatory open and closed comedones, and inflammatory papules and pustules once a week. After a experiment self-assessment was checked. As the result of the study, we found that a significant difference was observed in the mean counts and self-assessment of the experimental group. So we concluded that Herba Houttuyniae has a clinical effect on the acne.

Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis (AD). Atoberry is the herb medicine extract which is composed with Spirodelae Herba, Xanthii Fructus, Houttuyniae Herba, Taraxaci Herba, Retinervus Luffae Fructus, Platycodi Radix, and Scutellariae Radix. In this study, we investigated the antioxidant and anti-inflammatory effects of Atoberry in AD-like skin lesion NC/Nga mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinse (Df) extract. Atoberry significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and superoxide dismutase (SOD) activities in dose dependant. Topically applied Atoberry significantly reduced clinical severity score, ear thickness and histological grade in AD-like skin lesion NC/Nga mice. In addition, the serum levels of IgE, NO and prostaglandin E2 were significantly reduced by Atoberry. Futhermore, skin tissue levels of SOD, catalase and glutathione peroxidase (GPx) were significantly reduced by Atoberry. These results demonstrate that topical application of Atoberry may be improve the AD-like skin lesion by antioxidant and anti-inflammatory effects.
