Function

1.Erectile Dysfunction

Yohimbe bark extracts are widely promoted online and in health food stores as a natural aphrodisiac to increase libido and treat erectile dysfunction. However, there is no evidence to show that the herbal supplements are effective. Most clinical studies have looked at the drug yohimbine and not the herbal extract yohimbe.Studies on the effectiveness of yohimbine have had conflicting findings. For organic erectile dysfunction (erectile dysfunction due to a physical problem), some studies suggest it may be beneficial for men with organic erectile dysfunction. Other studies it may be no more effective than a placebo.

A German study examined whether 30 mg/day of yohimbine for four weeks would help men with erectile dysfunction not due to a physical problem. Yohimbine was found to be more effective than placebo (71 percent vs 45 percent).

2.Weight Loss

Yohimbine has been found in preliminary research to increase lipolysis by increasing the release of norepinephrine available to fat cells and blocking alpha-2 receptor activation. However, a controlled study found that 43 mg/day yohimbe had no effect on body weight, body mass index, body fat, fat distribution, and cholesterol levels.1

3.Depression

Yohimbe has been promoted as a herbal remedy for depression because it blocks an enzyme called monoamine oxidase. However, this is only found in higher doses (over 50 mg/day), which is potentially unsafe
