Homeopathic stuff is typically harmless but there was a case in the 2000s where Zicam sold a "homeopathic" nasal spray at a low dilution of zinc (i.e., it actually contained zinc) as a cold remedy. The result: hundreds of people caused permanent damage to their senses of smell.

This changed my attitudes towards consumer protection a lot. I thought I was smart enough to tell medicine from snake oil, but Zicam ads had high production values and looked just like ads for Tylenol or NyQuil. It was a far cry from the laughable marketing of that other '00s homeopathic product, HeadOn. (Apply directly to the forehead!) So I thought it was a legit product until the news of the lawsuits came out.
