Quackwatch has a document on Raindrop Therapy and its creator Gary Young. I encourage any therapists interested in Raindrop Therapy to read this document before proceeding. http://www.quackwatch.org/11Ind/young.html

Dec 2005 update: There is a rebuttal to the QuackWatch article at: http://enews.essentialscience.net/public/QckRebut.pdf
I have to say that Quackwatch gets a LOT of things wrong. In fact, most of the areas where I have any expertise, QuackWatch gets wrong. I’d delete this article, in fact, except so many people find it. Perhaps this will give people enough to let their intuition be their guide. I have a number of friends who use the essential oils although not as part of “raindrop therapy” and are very pleased with the quality.
