The active component in hot peppers that gives them their heat is called capsaicin, and the hotter the pepper, the higher the level of capsaicin there is. While rubbing something that seems flaming hot onto your sore joints doesn’t initially seem like it would help arthritis, capsaicin cream is commonly sold OTC as a pain reliever. Why? Capsaicin depletes a neurotransmitter called substance P, which is responsible for sending pain signals to our brain. If we block the big P, we never get the memo that something is hurting, and therefore end up pain free. Instead of paying for the arthritis cream at the store, try making your own. It offers great peace of mind to know what exactly you are absorbing into your skin, and it’s rewarding to make yourself.
