This is a little info about this plant aphrodisiac:
Yohimbe
Alternate Names: Pausinystalia 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. Yohimbine is a
prescription drug in the United States for the treatment of erectile
dysfunction. Its popularity has waned since the introduction of
Viagra. Yohimbe bark extracts are also sold in health food stores and
online.
In Germany, it is not approved for use. Yohimbe can cause a dangerous
rise in blood pressure, as well as anxiety and other side effects.
Traditionally, yohimbe was used in Africa for fever, coughs, leprosy,
and as an aphrodisiac.
Today, yohimbe is promoted for the following conditions:
Erectile dysfunction: Yohimbe bark extracts are widely promoted as a
natural aphrodisiac to increase libido and treat 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.
For organic erectile dysfunction (erectile dysfunction caused by a
physical problem), one small uncontrolled study found that yohimbine
was beneficial. 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%).
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.
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.
