Cayenne pepper benefits those with scabies because it can be used to alleviate pain associated with scabies. Cayenne contains capsaicin, a chemical that reduces pain sensations when applied to the skin. (3) Capsaicin can also relieve itching by desensitizing neurons in the skin. However, one study found that it can cause a burning sensation that 30 percent of patients experience when using capsaicin topically. (4)
There are even claims that applying cayenne pepper to the skin can kill scabies mites. There are no studies to back up these claims, but many people dealing with scabies have attested to cayenne’s ability to kill parasites when applied topically. One way to use cayenne is to add one cup to hot bathwater, sit in the bath until the water gets cold and then rinse your body. Make sure that the cayenne does not get into your eyes, as it may burn or sting. You can also create a paste with cayenne and one to two drops of water. Apply the paste to visible burrows beneath the surface of the skin.
