:::I've had another go at restructuring the lede, editing the last three paragraphs so that they deal with (1) evidence of efficacy; (2) scientific plausibility; (3) ethics, regualtion & prevalence.  There's still some tidying up to be done, for example it isn't really necessary to quote from the sources in a lede, which is supposed to summarise the article.  I think we also perhaps ought to change "Scientific research has repeatedly found homeopathic remedies ineffective" to something more along the lines of "scientific research has repeatedly failed to demonstrate efficacy", although this would also require rewriting the second part of the same sentence so that it doesn't imply that research has failed to find the postulated mechanisms of action implausible.
