What is Yohimbe?
Yohimbe is an evergreen tree that grows in western Africa in Nigeria, Cameroon, the Congo and Gabon. The bark of the tree contains the active compounds called alkaloids. The principal alkaloid is called yohimbine.
The alternative medicine has actually been approved, in one specific form, by the FDA to be distributed by physicians treating erectile dysfunction. Other non-regulated forms are available as a vitamin compound.
For hundreds of years, people living in western Africa have ground up the bark of the trees Corynanthe yohimbe and Pausinystalie yohimbe. Both men and women ingested the mixed powder of yohimbe for increased sexual pleasure and endurance. Sometimes, higher doses were used in other capacities, such as spiritual rituals.
Chemical constituents of Yohimbe Extract
Yohimbe bark extract contains the active chemical yohimbine, also known as indole alkaloid, and is found in the bark of the Pausinystalia yohimbe tree.
Benefits of taking Yohimbe Extract supplements:
1) Erectile Dysfunction
Yohimbine has been found to relax and dilate blood vessels in the penis, resulting in increased blood flow and erection. It may also stimulate areas in the brain involved in sexual desire.
Studies on the effectiveness of yohimbine have had conflicting findings. For organic erectile dysfunction (erectile dysfunction caused by a physical problem), one small uncontrolled study found that yohimbine was beneficial for men with organic erectile dysfunction. Another study found it was no more effective than a placebo.
Yohimbine appears to work better for erectile dysfunction not caused by a physical problem. A German study examined whether 30 mg/day of yohimbine for 4 weeks would help men with erectile dysfunction not due to a physical problem. Yohimbine was found to be more effective than placebo (71% vs 45%).
2) Weight Loss
Yohimbine has been found 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.
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).
4) Sports Nutrition
As a stimulant, yohimbe may theoretically increase fat metabolism. The main alkaloid in yohimbe is yohimbine, which can be toxic if used in excess amounts. This alkaloid blocks a particular receptor that increases sympathetic nervous system output so you get more adrenaline and, thus, increased metabolism.
Side effects and safety of Yohimbe Extract
Higher doses of oral yohimbine may create numerous side effects, such as rapid heart rate, overstimulation, insomnia and/or sleeplessness. Some effects in rare cases were panic attacks, hallucinations, headaches, dizziness.
