The very second reference on that page is to a paper by the fraudster. The first link is to a compound study of five studies, including one of the fraudster. The fourth reference cites Aggarwal as well, and no doubt the chain continues.

I can't tell how much of the linked effects are based on retracted papers (it's all members-only), but I wouldn't trust these websites too much until every dubious paper has been retracted and websites like these have been updated, if they will be updated at all.

Most scientific research into the substance seems to be based (at least in part) on Aggarwal's work, so in turn most of the research needs to be re-evaluated; that's a lot of tedious work, and I'm not sure if websites like these will have the manpower to do that.
