Chris Kilham, a.k.a. the Medicine Hunter, has been studying medicinal herbs for 46 years. He is an author, ethnobotanist, explorer, and ultimately a searcher for truth in medicine, the universe, and within the human consciousness. You may have seen him on the Dr. Oz Show or Fox News, or read about his travels in the Amazon rainforest, the Himalayas, or Malaysia. MassRoots recently spoke with Chris, a contributor to next week’s first online annual Holistic Cannabis Summit, from his office in New York.
