That's news to me: After 40 years in medicine. I could find support for this only on a couple of "pop" websites promoting herbal sources for caffeine. I suspect it's made up, like many "natural medicine" claims. If you're really interested in this stuff, get with an evidence-based holistic physician or other practitioner in your community who can help you sort out what's actually true.
