Science: Adding Capsaicin Improves Anesthetic Treatment

"It's no secret what capsaicin, the fiery molecule of peppers, does to cell walls. In fact, it's now being used to open cells up to local anesthetics. Combine it with a new drug that works only from the insides of cells and you have a great system for relieving pain. From the article, 'QX-314 is known to reduce the activity of pain-sensing neurons in the nervous system and theoretically heighten pain thresholds. But there's a catch: Researchers found that "it wouldn't work from outside a nerve cell but it would work if you could get it inside," says Bruce Bean, a professor of neurobiology at Harvard Medical School and co-author of the new study.

And it's in the news again, this time applied to surgical wounds:

Capsaicin Tested On Surgical Wounds
from Slashdot by kdawson

Ponca City, We Love You writes "Bite a hot pepper, and after the burn your tongue goes numb. The Baltimore Sun reports that Capsaicin, the chemical that gives chili peppers their fire, is being dripped directly into open wounds during highly painful operations, bathing surgically exposed nerves in a high enough dose to numb them for weeks. As a result patients suffer less pain and require fewer narcotic painkillers as they heal. 'We wanted to exploit this numbness,' says Dr. Eske Aasvang, a pain specialist who is testing the substance. Capsaicin works by binding to C fibers called TRPV1, the nerve endings responsible for long-lasting aching and throbbing pain. Experiments are under way involving several hundred patients undergoing various surgeries, including knee and hip replacements using an ultra-purified version of Capsaicin to avoid infection. Volunteers are under anesthesia so they don't feel the initial burn."
