Chilli pepper does not harm those who have it. In addition, chilli peppers are good at soothing any kind of pain and swelling. They contain a substance called capcisine that promotes the production of the so-called substance P. The function of substance P is to distribute pain signals to the entire nervous system.
Capcisine depletes the P reserve of cells and prevents the sensitivity of the nervous system. Kapsiina creams are used against osteoarthritis and scar pains.
