UCI播客:药草吸引力

洋甘菊通常被认为是一种有益健康的物质,是治疗一些可能已经流传了几千年的疾病的天然药物。考古证据表明,早在80万年前,我们的祖先就把它和其他草药用于医疗用途。它们通常是由家庭长辈而不是医生开的处方,但新兴的研究正在验证草药的疗效,尤其是在降低血压方面。

In this podcast, we interview Geoffrey Abbott, a professor of physiology & biophysics in the UCI School of Medicine and senior author of a study on botanical folk medicines published recently in 美国国家科学院院刊. The researchers tracked the relationship of the human KCNQ5 potassium channel – known for its regulation of vascular smooth muscle tone – to genetic and culturally diverse herbal remedies traditionally used to reduce blood pressure, such as lavender, fennel seed and chamomile. After carefully controlling for other variables, they were able to pinpoint the hypotensive (blood pressure-lowering) function of specific herbs down to a microscopic level. According to Abbott, the results not only confirmed that KCNQ5 is activated by hypotensive botanical medicines, but also demonstrated that this phenomenon is highly specific: The hypotensive herbs were the only plants in the study to activate KCNQ5, and they did not open other closely related potassium channels. The future of medicine may just rest in the molecular secrets of ancient cures.
