I have reverted to the version which virtually everybody (except for two) agrees upon. As Mr darwin, who can hardly be descibed as a supporter of homeopathy, puts it: "One doesn't have to agree with homeopathy to acknowledge that homeopathic practicioners recommend or use this or that species of plant, and it only has to be prominent within the homeopathic literature to merit a mention in the article." I think that sums up the view of about 5 or 6 editors here so it is clear that those editors simply do not accept ScienceApologist or PoupononToast's new Wiki guidlines for inclusion. Until those guidlined gain some greater support, the reference should clearly remain.
