Deletion of Michael Tierra

Comment: He does appear to be a founder of the American Herbalists Guild,http://www.americanherbalistsguild.com/who-we-are-our-history but its notability is also questionable. In a search I found only his own books, no coverage of him as required to meet . Most of the article is not even about him, but is a defense of various systems of herbology, with lengthy quotes from Tierra and other practitioners
