Ep 147: Can ginseng make you faster?/Dr. Jim Taylor PhD
In this episode:Ginseng is a root purported to have myriad beneficial properties making its use widespread in Chinese medicine and across the far east. Recently, a listener asked if this traditional remedy might also have benefits for athletes? On the Medical Mailbag, we dig in to the evidence for and against. Dr. Jim Taylor is a PhD in psychology and has worked with many professional and high level age group triathletes. He believes that training the mind is as important as training the body and he thinks that there are ways to leverage psychology to extract mental marginal gains that add up to improvements in performance.
