Airborne, a popular herbal supplement, that was created by a teacher who was sick of getting sick all the time. But the company recently faced a class action lawsuit regarding false advertising because of advertisements that claimed Airborne could combat the common cold. The company has since dropped those claims but now says the product can boost your immune system so it can better fight off germs.

The defendants haven't admitted any wrongdoing, but they've agreed to pay a 23.3 million dollar settlement, issue refunds to consumers, and take out ads informing consumers how they can get their refund. A nutritionist for the non-profit organization Center for Science in the Public Interest stated that there was no evidence that Airborne can protect you from germs.
