RESUMO
Despite minoxidil and finasteride already being approved by the Food and Drug Administration (FDA) for the treatment of hair loss, it is important to identify new and innovative treatments for hair loss, such as looking for a solution in Chinese herbal medicine. One such treatment to consider is BeauTop (BT), whose primary ingredients include Panax japonicus (T.Nees), C.A. Mey. (Araliaceae), Astragalus membranaceus (Fisch) Bunge (Fabaceae), Angelica sinensis (Oliv.) Diels (Apiaceae), Ligustrum lucidum W.T. Aiton (Oleaceae), Rehmannia glutinosa (Gaertn.) DC. (Plantaginaceae), and Eclipta prostrata (L.) L. (Compositae). The aim of this study was to evaluate whether BT can promote hair growth in C57BL/6 mice and to investigate hair coverage, the expression of vascular endothelial growth factor (VEFG), and the numbers of hair follicles in growth phase after oral administration. A total of 12 C57BL/6 mice were divided into two groups: control group and treatment group BT. BT was administered orally as an extract at a volume of 0.6 g/kg. The control group was treated with distilled water. Each group was treated once a day for 12 consecutive days. To observe the expression of VEGF distribution, the number of hair follicles and the hair coverage were examined on days 4, 8, and 12. By comparing the treatment group and control group, we found that VEGF in the BT group on day 8 presented with a higher area percentage than the control group (p value = 0.003). Hair follicle counting results showed that the BT group was significantly higher than the control group on day 8 (p value = 0.031). Furthermore, hair coverage was shown to be significantly increased in the treatment group BT on day 8 (p value = 0.013). Taken together, these results suggest that Chinese medicine (BT) possesses the potential effect of promoting hair growth through VEGF expression. VEGF is considered the most important mediator for the process of angiogenesis involved in hair growth development.
RESUMO
The aim of the present study was to evaluate the treatment effects of BeauTop in alopecia by observing its effectiveness in improving androgenetic alopecia. Hair growth was observed using a dermatoscope and clinical photos, and was scored by three dermatologists. Dermatologists evaluated and selected suitable participants for this study using the Norwood scale or Ludwig scale. A total of 40 participants with androgenetic alopecia were recruited in this study, and 32 participants completed the 6-month trial. The results revealed that in the BeauTop treatment group, 9/17 participants (52.9%) showed increased hair growth. Changes in hair growth were as follows: No change, 47.1% patients; minimally improved, 5.9% patients; moderately improved, 29.4% patients; and significantly improved, 17.6% patients. In the placebo group, 2/15 participants (13%) showed increased hair growth. A Chi-square test was performed and attained a value of 0.01
RESUMO
BACKGROUND: Danggui Buxue Tang (DBT), an herbal formula containing Angelica sinensis (AS) and Astragalus membranaceus (AM) (AS:AM = 1:5, designated as DBT1 here), has been used in Chinese medicine to enhance qi and blood circulation. In addition, DBT has served as a treatment for atopic dermatitis in dogs in Taiwan. It also may improve fibrosis in a rat model of pulmonary fibrosis. OBJECTIVE: In this study, we evaluated the effect of oral administration of DBT1 in asthma in ovalbumin (OVA)-sensitized mice. METHODS: Female BALB/c mice were sensitized and challenged with OVA and fed with DBT1 or modified formulas of DBT1, designated as DBT2 (AS:AM = 1:1) and DBT3 (AS:AM = 5:1), from days 21 to 27. RESULTS: DBT1 suppressed airway hyperresponsiveness and eosinophil infiltration in bronchoalveolar lavage fluid (BALF) and lung, and Th2-associated cytokines and chemokines were inhibited in BALF. In addition, levels of OVA-immunoglobulin E (IgE) also were suppressed in serum. However, treatment with DBT2 or DBT3 showed no improved effects relative to DBT1 in treating asthmatic symptoms. CONCLUSIONS: These results suggest that orally administered DBT (DBT1) can reduce allergic reactions in OVA-sensitized mice.
