If you are interested in how to train safely in the sun, I’ve just written an article for YMAA on sunburn prevention and herbal treatment. You’ll find it here.
Here are the slides for the Western Herbs for Martial Injuries seminar. They are a pdf form of the PowerPoint slides. They are an introductory word on the topic only. If you want more information, check out my book Western Herbs for Martial Artists and Contact Athletes.
