You'll probably remember a few blogs here on this topic - ranting against the money that the NHS wastes on this, and against the support of this snake oil by Bigears. Well, the US government has decided to support me on this. In future, homeopathic "remedies" have to have a label that says "This product doesn't work" or similar.
I expect the vendors will find ways to wriggle round this, and consumers who don't bother reading the product packaging will continue to be duped. But probably the biggest way they'll get round this is by using the same method used by cosmetics and other advertisers; they'll truthfully use the "8 out of 10 cats" line, as in "8 out of 10 cats prefer Whiskas", or "reduces the appearance of wrinkles".
So we have to continue the struggle against snake oil.
