Reduces inflammation:
Onions contain antioxidants such as quercetin, which reduce inflammation. Although most research on quercetin has focused on its application rather than topical application, some people believe that applying onion topically to the skin has similar benefits in reducing local inflammation and pain.
Improved Blood Circulation:
Another benefit of onion in socks is that it improves blood circulation. Applying onions to your feet is said to improve blood flow due to its sulfur compounds. This idea is again consistent with reflexology, where trigger points on the feet improve blood circulation to the corresponding parts of the body.
Odor Neutralizer:
Surprisingly, some believe that onions can help neutralize bad foot odor despite their pungent smell. The antibacterial properties of onions are responsible for this effect, as they may kill odor-causing bacteria.
