Ginseng root is a well-liked natural medication. Like the phrase panacea, ginseng’s Latin identify, panax, is derived from the Greek for “cure-all.” It can lengthen the lives of fruit flies and microscopic worms, however not mice. What about folks?
Well, there have been greater than 100 medical trials utilizing varied ginseng formulations, however the outcomes have been underwhelming. A meta-analysis of randomized, double-blind, placebo-controlled trials discovered ginseng didn’t seem to considerably have an effect on the period of sickness, however did seem to cut back the chance of creating acute higher respiratory infections within the first place. Digging deeper, nevertheless, the preventive profit seems restricted to Asian ginseng, which reduce an infection danger in half in comparison with placebo––versus American ginseng that solely decreased danger 16 p.c, which didn’t attain statistical significance.
Asian ginseng can then be additional divided up by processing technique. “White” ginseng is Asian ginseng root that’s merely been washed and dried, whereas “red” ginseng is identical root, however undergoes an extra step of steaming earlier than drying. Red ginseng is commonly used for male erectile dysfunction. While it doesn’t seem to assist with feminine sexual dysfunction, a meta-analysis of a half-dozen randomized managed trials discovered that 4 to 12 weeks of 1.8 to 3 grams a day of Korean purple ginseng can enhance erectile disfunction, in comparison with placebo. Fifty-eight p.c of males skilled an enchancment in sexual operate, in comparison with 20 p.c of males within the placebo group. This could also be as a consequence of an enchancment in artery operate demonstrated inside three hours of consumption.
Of course, that is assuming there’s really ginseng in your “ginseng.” Ginseng is a multibillion-dollar business, and, as such, suffers from intentional contamination with cheaper filler substitutes––some of which might not be benign. If your “ginseng” complement seems to simply be powdered soybeans, then you definately’ve simply wasted your cash. But, for instance, if it’s been spiked with illicit horse painkiller, it’s worse than a waste. A examine of the greater than 500 ginseng merchandise bought in a dozen international locations throughout six continents discovered that 24 p.c had been adulterated. This is in keeping with so-called “immune-boosting” dietary supplements usually. A 2022 evaluation discovered most such merchandise did not match what was on their labels.
Maybe it’s good there’s no ginseng in your ginseng? From an oxidative stress standpoint, American, Chinese, and Korean ginseng all have been proven to acutely defend towards free radical-induced DNA harm inside hours of consumption. But one longer-term trial raised purple flags. Although 4 weeks of Korean ginseng decreased ranges of oxidative stress, 4 months of American ginseng (a few quarter-teaspoon a day of complete root powder) prompted an uptick in DNA harm. Until it may be proven that power consumption of different ginsengs isn’t additionally DNA-damaging, I’d advocate steering clear.
Approximately 10 p.c of customers undergo from what’s been termed ginseng abuse syndrome, which manifests as high blood pressure, nervousness, sleeplessness, pores and skin eruptions, and morning diarrhea. Of course, it might not really be from ginseng itself, however reasonably adulterants in some supposed ginseng product.
What for those who randomize folks to ginseng that’s been formally authenticated? In a multicenter, double-blind, randomized, placebo-controlled security trial, a thousand folks had been randomized to 2 grams a day of purple ginseng or placebo for six months. In the ginseng group, 345 opposed occasions had been recorded. But the placebo group had 389 opposed occasions. Each of the highest 5 “side effects” had been documented extra typically within the placebo group.
Outside of a medical trial, although, it’s arduous to know what you’re going to get. Aside from the abuse syndrome signs, there have been case stories of manic psychosis, estrogenic results, and elevated surgical bleeding. And so, some advocate ginseng must be averted in these anticipated to endure surgical procedure, these with a predisposition to mania, estrogen-dependent illness, hypertension, or hyperthyroidism.
