evidence: Like so many questionable bits of scientific misinformation, the claim that putting onions on your feet will do something unspecified that has to do with "toxins" is repeated with similar or identical language on many different web sites. [...] The Chinese found that there are thousands of tiny nerve endings on the bottom of the feet. These nerve endings act as access points to the internal organs. They are also closely linked to the nervous system. Onions have strong anti-bacterial and anti-viral properties. When you cut an onion and place it on the bottom of the foot, it gets right to work removing toxins and healing your body. [...] All things considered, the evidence presented to support this fairly outlandish notion is either false or misleading, and we cannot find any plausible mechanism for a raw cut onion stuffed in your sock to reduce any disease.
