Researchers at the University of Wisconsin have reported that those who suffer
from post-herpetic neuralgia or pain following an attack of shingles can now get
relief through a patch of Capsaicin, the active ingredient of chili peppers.
Shingles is caused the varicella zoster virus, which also causes chicken pox.
Shingles results in the occurrence of painful rashes on one side of the body and
the pain can persist even after the rashes have disappeared. Researchers have
now seen in a study patients with post-shingles pain that capsaicin acts on
pain-responsive pain fibers. In the study, participants were treated with the
capsaicin patch showed 33 per cent reduction in pain compared to four per cent
of those who were given a placebo.
