What Is Yohimbe?

Yohimbe is an evergreen plant from the Rubiaceae family native to Western Africa. Yohimbe bark contains, among other chemical substances, an organic alkaloid called yohimbine, which is used to make medicines and supplements. Traditionally, yohimbe bark has been used as a stimulant tonic for men, as a performance enhancer for athletes, and as an aphrodisiac. The prescription drug for the treatment of erectile dysfunction uses a form of yohimbine called yohimbine hydrochloride that is made in the laboratory (1).

Food supplements using yohimbine hydrochloride as their active ingredient are banned in the USA. Hence, this article focuses on yohimbe supplements that use yohimbe bark extract or yohimbine.

Stylecraze TriviaYohimbine is approved as a drug in veterinary medicine to counter the effects of xylazine (used for sedation or as an analgesic) in dogs and deers.

In the next section, let us understand how yohimbe works.

How Does Yohimbe Work?

Yohimbine, the most important bioactive alkaloid in yohimbe bark, is an alpha-2-adrenoceptor antagonist that works on the central and peripheral nervous systems. Alpha-2 adrenoceptors are located at various places within the body and play a role in managing heart rate, blood pressure, and central nervous system functions, among others (1). They also may contribute to erectile dysfunction. Yohimbe blocks the alpha-2-adrenoceptor and may help treat erectile dysfunction. However, further studies are essential to completely understand the mechanism of action and its efficacy (2).

Yohimbe also may block the alpha-2-adrenoceptors in fat cells. It helps break down stored fat and makes it readily available as fuel for the body (3), (4).

Studies on yohimbe bark extract and yohimbine in food supplements are still nascent. But yohimbe does seem to have some benefits. Let us understand them in detail.

Benefits Of Yohimbe: Looking At Claims And Evidence

Yohimbe has been used in traditional medicine for ages. While the most widely claimed benefit is its action as a stimulating tonic for men, it may have other potential uses.

1. May Resolve Sexual Problems Arising From Certain Medications

Some medications that are used to treat depression, obsessive-compulsive disorder, or anxiety, often cause sexual impotence as a side effect. A study supports the effectiveness of yohimbine as a treatment for improving libido and sexual function. However, more controlled studies are required to accurately understand the dosage and safety of yohimbine in this regard (5).

Also, while the study mentions yohimbine, it is unclear if it is yohimbine in its organic form or yohimbine hydrochloride that is used. Talk to your healthcare provider for more information in this regard.

2. May Help Treat Erectile Dysfunction

You have probably heard about yohimbe supplements as a solution for erectile dysfunction. While supplements are not regulated by the FDA and may vary in terms of their yohimbine content, there is some evidence to suggest that yohimbine could be a potential solution to this problem. Studies suggest that the benefits of yohimbe medication can outweigh its risks. Serious adverse effects were rare, and they could be reserved even if they occurred (6).

Yohimbe extracts in the form of yohimbine hydrochloride are available as prescription medications for treating erectile dysfunction. Speak to a healthcare professional before taking any such medications.

3. May Support Weight Loss

Combining exercise with yohimbe may promote weight loss. This because yohimbine, a natural alpha-2 adrenoceptor antagonist present in yohimbe supplements, helps break down the stored body fat so that it gets used up. This holds true especially if you are in a fasted state (where your body is looking for fuel to feed on) or when you are involved in physical exercise (4).

A study conducted to observe the changes in body composition (and performance) in soccer players found that those taking a specific dose of yohimbine saw significant body fat loss (6).

On the contrary, another study found a lack of efficacy in yohimbine for the treatment of obesity (8). Hence, more concrete research is warranted to understand the role of yohimbe in aiding weight loss.

4. May Improve Performance In Athletes

Yohimbe extract and bark and the over-the-counter supplements are commonly used for their potential action as an energy enhancer (9). However, there is not enough evidence to suggest that yohimbe can improve athletic performance.

A study conducted on soccer players given specific doses of yohimbine revealed that there was no marked difference in their performance as compared to the group that received a placebo (7). Also, an article published in the Journal of Dietary Supplements suggests that there is no conclusive evidence for the drug to enhance physical performance (10).

Yohimbe has potential as medicine with certain benefits that you may be interested in. However, yohimbe dietary supplements are unregulated and may be inconsistent with their labels, ingredients, composition, safety, and efficacy. Let us look at some of the reported yohimbe side effects.

Yohimbe Side Effects and Potential Allergies

Yohimbe may cause some side effects when used to reduce sexual side effects of depression medications. These may include (5):

Excess intake of yohimbe as a drug for treating erectile dysfunction may cause (11):

In a study, a young girl taking yohimbe for weight loss experienced a few severe side effects that included (12):

Another case study looking at two yohimbe-related deaths compiled some more reported side effects of the drug. These side effects were observed at different doses of yohimbine, beginning with as low as 0.2 g. The side effects included (13):

What Are The Precautions To Consider Before Using Yohimbe?

Yohimbe is very commonly available as a street drug, over-the-counter pill, and herbal supplement. It is often used without prescription as an aphrodisiac and weight loss pill. Research on yohimbe bark extract used in dietary supplements is insufficient and the supplements themselves are unregulated by the FDA.

Yohimbe extract, purified in the lab to form yohimbine hydrochloride, has some research to support its use as a prescription drug for erectile dysfunction. Given the potential adverse effects of yohimbe, you need to consider certain precautions before using it personally:

  1. Most yohimbe products do not contain sufficient or accurate information on their labels. In an analysis of yohimbe supplements spread across 49 brands, only 2 out of the 49 brands of the supplement had accurate information about the quantity of yohimbine as well as the potential adverse effects of the product. It was also found that 39% of the customers used either highly processed or synthetic yohimbine. Most of the labels on the supplements were inaccurate, and the quantity of yohimbine used in them ranged from 23 percent to 147 percent (14). Be aware of this, as such supplements may either be ineffective or cause side effects when taken in excess.
  2. Yohimbe products can induce psychiatric adverse effects in healthy people. They may also exacerbate psychiatric conditions in people with diagnosed or undiagnosed psychiatric conditions, including anxiety (15).
  3. Yohimbe has not been studied for safety in pregnancy and lactation. Hence, pregnant or breastfeeding women must avoid yohimbe-related products (1), (16).
  4. You should not take yohimbe if you have renal and hepatic problems, hypertension, glaucoma, and cardiac impairment (17).

Yohimbe Drug Interactions

Yohimbine may adversely interact with certain prescription drugs. According to a scientific opinion on the evaluation of the safety of yohimbe, some interactions are listed here (1), (16).

Yohimbe is also known to interact with alcohol. Mixing the two may impair one’s driving ability (17).

Stylecraze TriviaPhenelzine (Nardil) and tranylcypromine (Parnate) are two commonly used monoamine oxidase inhibitors (a type of antidepressant drug) that can potentially have drug interactions with yohimbe.

With the important precautions taken into consideration, here is some more information if you want to proceed with yohimbe.

How To Use Yohimbe

Yohimbe is available as prescription pills and an intravenous drug, as well as in the form of herbal supplements for oral use. For use as a fat loss aid, you may use it in a fasted state or before exercise (4). There is no standardized yohimbe dosage as it is a dietary supplement not regulated by the FDA. Use caution and your doctor’s advice before using any product containing yohimbe extract.

Yohimbe is a plant that produces an alkaloid called yohimbine, which can potentially help improve symptoms of erectile dysfunction and may aid weight loss. While yohimbine hydrochloride, a processed form of yohimbine, is approved for use as a prescription medicine to treat erectile dysfunction, the herbal supplements containing yohimbe extract have not been studied widely. The potential adverse effects of yohimbe, some of which are severe, have raised questions regarding its safety and efficacy. Hence, always consult your doctor before using yohimbe.

Yohimbe is an herbal supplement with medicinal properties. It has been primarily used to treat erectile dysfunction. The many benefits of yohimbe can be attributed to its antioxidant compound, yohimbine. The use of this dietary supplement may resolve erectile dysfunction and support weight loss. However, excess intake of this supplement may cause high blood pressure, increase urination frequency, and lead to mild anxiety. In addition, yohimbe bark extract may cause allergic reactions in some people. Hence, consult a healthcare professional before using it. If you experience any adverse effects, stop using it and immediately consult your doctor.
