The current case report presents the combine effect of four herbal components as a traditional treatment of IBS. Method: The herbal components were purchased from the local market. The components including Lipidium sativum L., Trigonella foenum-graceum L., Myristica fragrance Hoyutt. and Apium graveolens Linn were ground and mixed well (dry weight), and took orally for two days as advised by the local healer. Results: The symptoms included loose bowel movements accompanied by prolonged flatulence abdominal cramping, faecal urgency as well as mucus discharge were improved and remain suppressed for 5 to 6 months afterthe treatment with multi-herbal formula. Conclusion: The current case report showed that the multi-herbal formula might be a promising treatment for IBS-diarrhoea.展开更多

Propionibacterium acnes (P.acnes) has a strong proinflammatory activity and targets molecules involved in the innate cutaneous immunity on keratinocytes by acting on TLR-2, leads to the development of comedones. GMP, a multi-herb extraction, targeted most of the major pathogenic features of acne with desired physicochemical traits. It strongly suppressed P.acnes growth, and reduced inflammation by suppressing the TLR-2/NF- kB pathway in SZ-95 sebocytes and HaCaT keratinocytes. GMP exhibited a marginal effect on cell viability and may have modulated hyper-keratinization of the epidermis. These results demonstrate the clinical feasibility of applying GMP for the treatment of acne.展开更多
