Capsaicin, A Weapon for most kind of pain

A derivative of chili peppers, capsaicin, which gives peppers their heat, soothes pain when applied to the skin. Studies have shown it to be helpful in relieving back pain as well as pain caused by arthritis, shingles, headaches, fibromyalgia, psoriasis, and diabetic neuropathy. In a study at Case Western Reserve University of Ohio, 80 percent of patients with arthritis reported a decrease in pain after using topical capsaicin for two weeks. A University of Toronto study found that capsaicin cream significantly reduced pain in patients with post-herpetic neuralgia nerve pain (persistent pain in some people who have had shingles). Two years later, 86 percent of patients reported it was still effective.
