Reverted unsourced claims and text that read like promotional material edit

I reverted the addition of a large chunk of text, some of which was comprised of unsourced scientific claims, and the rest of which read like promotional material for Dr. Wichai Cherdshewasart and an herbal supplement. Some examples included:

Found in the hills of Thailand, a natural compound is definitely creating a worldwide sexual sensation. Butea Superba has a molecular structure that makes it a natural PDE 5 inhibitor which creates increased blood flow particularly in small blood vessels, making it a perfect natural male enhancer.

This statement was not sourced in any way, and it reads like an ad.

The men taking part in clinical trials also reported an increase of energy without any negative increase in nervous system stimulation. Which proves Butea Superba can be used safely with no known side effects?

Again, reads like an ad, and makes claims without any references. Check the diff if you want to see the rest, but it goes on like this.

Some of this information may be relevant to this article, but if it's to be added, then several things need to happen. First, reliable sources must be found and cited for any claims of medical benefits. The guidelines concerning reliable sources for medical articles should help here. Non-medical claims also need to be sourced with reliable sources. Second, the text needs to be rewritten to be more neutral and less like a promotional site for a supplement or a doctor. Also keep in mind that this article is about a plant, not about a doctor. The doctor's qualifications have nothing to do with the plant. If he has conducted good research, and his findings are published in respected, peer-reviewed journals, that's good enough. If not, then his research doesn't constitute a reliable source. Either way, his credentials and his appointments don't matter. --Transity (talkcontribs) 15:22, 22 June 2009 (UTC)Reply

In addition, the added (and now removed text) was a copy/paste from numerous other sites (see here and here, for just two examples). This is an apparent copyright violation. Please do not copy/paste text into Wikipedia. --Transity (talkcontribs) 20:03, 25 June 2009 (UTC)Reply
