Treating Acne With Barberries | Care2 Healthy Living

We hear a lot about traditional Chinese herbal medicine, but less about the herbs used in Japan, where there is a root called Rhizoma coptidis that appears to have similar anti-acne activities to drugs like Accutane, a drug infamous for its side effects that has been pulled from the market. But there are side effects to the root, too. A poor fellow took it to clear up his skin and made things much worse.

The anti-acne active component of the root is thought to be berberine. Is there any way to get the active ingredient in a safer plant? Yes, apparently in barberries. You may remember barberries as being perhaps the most antioxidant-packed dried fruit available (see my video Better Than Goji Berries). You can find them cheap at Middle Eastern grocers, since they’re used to make a signature Persian rice dish. Their taste is described as “pleasantly acidulous,” which is just doctor-speak for sour. I love sprinkling them on my oatmeal just because I love their taste, but, evidently, they have played a prominent role in herbal healing for thousands of years around the world and have been described flamboyantly in a pharmacology journal as an “herbal remedy [that] has no match in serving the human race.” And I just thought they were kind of tangy.

The problem with the herbal medicine literature is that there is often a long, impressive list of traditional uses, but little or no science to back it up. And what does exist is often either in vitro or animal data that has questionable clinical applicability. Who cares, for example, if barberries induce menstruation in a guinea pig—except maybe the guinea pig? So, you end up with drug companies injecting herbs into the penises of rabbits in hopes of coming up with the next Viagra, but they conduct few, if any, human studies.

I’ve seen petri dish studies over the years suggesting anti-cancer effects of barberries on human tumor cells in vitro or having anti-acne effects on hamsters, but there weren’t any such human studies… until, now.

Evidently, there had been anecdotal reports of acne clearing up after barberry juice consumption, so researchers decided to put it to the test in a double-blind, randomized, placebo-controlled clinical trial of fifty 12- to 17-year-olds with moderate to severe acne. Half got a sugar pill, and the other half got the equivalent of about a teaspoon of dried barberries three times a day for a month.

The results were remarkable. After four weeks on the…
