Reports this morning from consumer organizations on the dangers of Yohimbe. Here is Prostate.nets review:
Yohimbe (Pausinystalia yohimbe) is an evergreen tree that grows in various locations throughout the African continent. Traditionally yohimbe was used in Africa to treat fever and leprosy, and as an aphrodisiac. The bark of the tree contains alkaloids, the main one of which is called yohimbine, which you may recognize as a prescription drug used to treat erectile dysfunction, although it is rarely used today since Viagra and other ED prescription drugs hit the market.
Yohimbe bark extract, however, is popular among some men who use it to treat erectile dysfunction, even though there is scant evidence that it works for this purpose. Yohimbine, on the other hand, has been shown in some studies to relax and dilate blood vessels in the penis, which results in an erection. Not all studies of yohimbine and ED have resulted in positive outcomes, however. While one small study found that yohimbine helped men whose ED was caused by a physical problem (Guay 2002), another reported that yohimbine was no more effective than a placebo. (Morales 1987)
As a dietary supplement, the dried bark of the yohimbe tree is available in capsules, tablets, and as a tea. Because the dose range is very narrow – take too little and it doesn’t work and take too much and it is toxic – use of this herb is not recommended. The Food and Drug Administration has received reports of seizures and kidney failure associated with use of this herb. Even normal “safe” dosages may cause dizziness, nausea, insomnia, anxiety, a rise in blood pressure, and rapid heartbeat, and overdose can be fatal. Although you will see claims on the internet that this herb can produce great results in the bedroom, there are many other herbal remedies for ED that are much safer and likely more effective.
