CAPSAICIN, the pungent principle in red pepper (paprika), is a potent irritant causing a sensation of burning pain. After initial violent stimulation, however, this substance induces a selective insensitivity to pain (desensitization) elicited by chemical agents1,2. This long-lasting insensitivity is accompanied by ultrastructural changes in the mitochondria of one type of neurone in the spinal ganglia3.
