A tropical African tree (Pausinystalia yohimbe synonym Corynanthe yohimbe) of the madder family whose bark yields yohimbine. [1]
Yohimbine is an indole alkaloid ester very first recognized in numerous organic types by the American botanist R. Raymond-Hamet in 1934. Today its main sources are the African evergreen yohimbe (Pausinystalia yohimbe) and Indian snakeroot (Rauwolfia serpentina). Yohimbe bark is offered over-the-counter as a natural aphrodisiac. Yohimbine hydrochloride is a prescription drug that has been used to treat erectile dysfunction with differing outcomes. [2]

Generic Call



A plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of impotence. It is also alleged to be an aphrodisiac.


Indicated as a sympatholytic and mydriatic. Impotence has actually been successfully treated with yohimbine in male clients with vascular or diabetic origins and psychogenic origins.


Yohimbine is an indolalkylamine alkaloid with chemical resemblance to reserpine. Yohimbine obstructs presynaptic alpha-2 adrenergic receptors. Its action on peripheral blood vessels resembles that of reserpine, though it is weaker and of short duration. Yohimbine’s peripheral autonomic nerve system impact is to increase parasympathetic (cholinergic) and decrease supportive (adrenergic) activity. It is to be noted that in male sexual performance, erection is linked to cholinergic activity and to alpha-2 adrenergic blockade which may theoretically lead to increased penile inflow, reduced penile outflow or both. Yohimbine applies a promoting action on the state of mind and might increase anxiety. Such actions have not been sufficiently studied or associated with dosage although they appear to require high doses of the drug. Yohimbine has a mild anti-diuretic action, most likely through stimulation of hypothalmic center and release of posterior pituitary hormone. Supposedly Yohimbine puts in no considerable influence on cardiac stimulation and other results moderated by (beta)- adrenergic receptors. Its impact on blood pressure, if any, would be to lower it; nevertheless, no adequate studies are at hand to quantitate this effect in regards to Yohimbine dosage.

Mechanism of action

Yohimbine is a pre-synaptic alpha 2-adrenergic obstructing agent. The specific system for its usage in impotence has actually not been totally illuminated. Nevertheless, yohimbine might exert its useful impact on erectile ability through blockade of main alpha 2-adrenergic receptors producing an increase in understanding drive secondary to a boost in norepinephrine release and in firing rate of cells in the brain noradrenergic nuclei. Yohimbine-mediated norepinephrine release at the level of the corporeal tissues may likewise be included. In addition, useful effects may involve other neurotransmitters such as dopamine and serotonin and cholinergic receptors.

Uses of Yohimbe

Yohimbe is a natural organic supplement that is highly related to anti-aging impacts. Yohimbe has a long history of use in Western Africa, and is still commonly used there today, to deal with a variety of sexual disorders, consisting of low libido and impotence.

Medically, yohimbine is a pre-synaptic alpha-2-adrenergic blocking agent, which is capable of increasing considerate nerve system activity, therefore leading to increased quantities of epinephrine (also known as adrenaline) and norepinephrine in the blood stream.

The main effects epinephrine and norepinephrine have on the body include increasing blood pressure and heart rate. Yohimbe is also often used for weight reduction, although the proof supporting this claim is inconclusive. [4]

How to Utilize

Look for yohimbe in capsule/tablet kind in natural food stores or online. It’s unusual to find the actual bark or extract form, although it might be possible. Dosage suggestions for yohimbe depend on its use. Dosages need to preferably be adjusted based upon body weight and in some cases sex.

There’s some issue that supplements identified as yohimbe include various quantities of the active component than the quantity that’s listed. The FDA strictly manages prescriptions consisting of yohimbine however not supplements. It can be tough to determine precisely how much active yohimbine remains in supplements due to how different growing and distributing variables impact the concentration.

These variables can include: the exact type of yohimbe tree bark that is utilized, what part of the tree the bark is drawn from, the maturity of the tree, how fresh the bark is, the processing techniques used to produce supplements, and how the supplements are shipped/exported and kept.

Below are general recommendations for yohimbe dosages, according to the condition or sign:.

For erectile dysfunction: adult males ought to take about 5.4 milligrams 1– 3 times daily. A lot of research studies have actually found positive outcomes when taking about 10– 20 milligrams total daily.

For hypotension in adults: take about 12.5 milligrams daily.

Start with a percentage of pre– workout (about 1/2 a scoop to see how it affects you). You can always include more next time if you feel the dosage was insufficient. However, starting with a conservative dose will help you prevent feeling jittery or anxious (which can sometimes take place when you over– take in stimulants).

What the research says

On an anecdotal basis, great deals of professional athletes and bodybuilders state they have actually seen terrific outcomes when they utilize supplements made with yohimbine. Exists any clinical evidence backing it, though?

The following are summaries of some research studies on Yohimbe for males and females that have shown appealing outcomes:.

Yohimbe And Weight Loss In Women

Research study on ladies reveals that yohimbine can be a really advantageous tool when it pertains to shedding stubborn fat.

One study on 20 obese ladies, which was released in the Israel Journal of Medical Science, for example, showed that yohimbine intake– when paired with a calorie– restricted diet plan– had the capability to increase weight loss. In the very same timespan (three weeks) the females who consumed yohimbine lost nearly three pounds more than the females who consumed a placebo.

The females who consumed yohimbine lost an average of 7.8 pounds, while those in the placebo group lost approximately simply 4.9 pounds.

Yohimbe And Body Structure

A research study on 20 male soccer gamers released in Research in Sports Medicine showed that those who consumed yohimbine were able to shed body fat (by an average of 1.8 portion points) without losing muscle. By comparison, the placebo group did not see any kind of significant outcomes.

Neither of the groups experienced any unfavorable negative effects when taking in yohimbine either.

Yohimbe And Improved Performance

Consuming supplements that contain yohimbine can likewise assist to improve your training efficiency.

A research study released in the American Journal of Physiology on 20 healthy male cyclists showed that yohimbine resulted in improvements in all aspects of their performance.

If you require aid pressing through your everyday cardio, a pre– workout supplement with yohimbine might be just what you require. [6]

The What And Why Of Yohimbe And Yohimbine

Recently yohimbe, or more accurately, its active ingredient yohimbine, has been the subject of some heated disputes among fitness enthusiasts and industry insiders alike. While it was originally considered a flop of a supplement, due to the fact that it did not increase testosterone levels as very first suspected, it had actually developed a bit of a cult following by some males for its reported ability to increase assistance sexual health.

However, some supplement manufacturers have actually recently declared that it can likewise assist in the loss of “persistent fat.” You understand; those areas that just won’t lean out no matter how hard you diet plan and workout. Usually, these areas are located in the midsection of guys, and on the glutes and thighs of females.

With all the claims and buzz being thrown around, we asked our own resident supplement specialist Dan Gastelu to do a little reading on what the present research states, and shed some light on the subject for us.

Yohimbe bark is mainly found being used in male aphrodisiac preparations, however some supplement manufacturers have actually declared that it can help fat loss as well.

Presently, yohimbe bark is primarily found being utilized in male aphrodisiac preparations, however some supplement manufacturers have declared that it can help weight loss also. Yohimbe is a little evergreen tree native to Africa, and the scientific name is Pausinystalia yohimbe. Chemically, Yohimbe bark consists of a compound called yohimbine, plus additional comparable substances, known as indole alkaloids.

Clinically, yohimbine is a pre-synaptic alpha-2-adrenergic blocking representative, likewise described as an alpha 2-adrenergic villain. This action increases supportive nervous system activity, and can lead to increasing the quantities of epinephrine (also called adrenaline) and norepinephrine in the blood stream. The understanding nervous system is involved in controlling the body’s reaction to stress, and also activates the battle or flight action.

The primary impacts epinephrine and norepinephrine have on the body consist of increasing blood pressure and heart rate. Paradoxically, in low does yohimbine may assist support healthy high blood pressure already in typical variety. This is thought to happen by causing dilation of blood vessels, thereby decreasing vascular resistance. This main nervous system stimulation causes anxiety in some individuals.

Yohimbine For Supporting Sexual Health

Constantly consult your physician when utilizing yohimbine-containing items. In the 1960’s, research studies were carried out utilizing a combination supplement called Nux Vomica, which included yohimbine and methyl testosterone. Nux Vomica was found to be efficient after 2 to 3 weeks of use for the most part, numerous negative effects were observed (see listed below). Bear in mind, nevertheless, no definitive studies using the botanical Yohimbe have actually been released which reveal the same results. Researchers E. Ernst and M.H. Pittler just recently evaluated a number of studies worrying making use of the supplement yohimbine for erectile dysfunction.

Major adverse effects observed in these short-term studies were infrequent and reversible. Negative effects reported using yohimbine consist of: nervousness, irritation, sleeping disorders, headache, skin flushing, anorexia, queasiness, stomach distress, diarrhea, vomiting, palpitations, tachycardia, dysuria, pain, increased high blood pressure, dizziness, sweating, weight gain, constipation, and anxiety. Always consult your medical professional when utilizing yohimbine-containing products.

Do not use while taking any medications, or if other medical issues exist, such as; angina pectoris, anxiety, other psychiatric disease, heart disease, hypertension, kidney illness, or liver illness. Do not go beyond the suggested dose for Yohimbine, as an overdose could, in extreme cases, lead to death.

Normally, yohimbine is not suggested for use by women for sex drive enhancement, and definitely is not to be used during pregnancy. [Note that a group of scientists carried out a study using yohimbine in women with decreased sex drive, and observed that the yohimbine supplementation was not effective in supporting their sexual health.]

Yohimbine And Weight Reduction

Making use of yohimbine for weight reduction is undetermined, and in this author’s opinion not to be suggested due to the prospective negative effects. Some research has been performed, and some of the key studies will be reviewed below. Keep in mind, however, that just because private investigators have conducted research on using the supplement yohimbine, does not indicate that such research studies need to automatically be utilized to back the self-prescribed use of this supplement.

Alpha-2 receptors prevail in websites of the body that tend to preferentially build up fat; abdomen, breasts, buttocks and thighs. When exposed to flowing catecholamines, such as norepinephrine and epinephrine, alpha-2 receptor websites hinder lipolysis (the release of fats), while the beta receptors promote lipolysis. Usually speaking, epinephrine, norepinephrine, glucagon, adrenocorticotropic hormonal agent (ACTH), and development hormonal agent stimulate the release of fatty acids from fat into the blood stream. When in the blood stream, fats are usually quickly oxidized if the fatty acid blood concentration is not raised from fat input resulting from a meal.

The What And Why Of Yohimbe And Yohimbine

Alpha-2 receptors are common in sites of the body that tend to preferentially collect fat; abdominal areas, breasts, buttocks and thighs.

Normally, when fat blood concentration is high, it prefers fat storage, which results from over-eating and lack of exercise. Although, keeping in mind that fats are constantly used for energy, it is the balance between the amount of fats consumed versus their use for energy that determines just how much ends up kept as fat. Of course, this is a rather simple description of fat metabolic process. There is much more associated with these fat storage/utilization dynamics, and those who want more insight on these dynamics need to click the link listed below to get more details on ISSA’s SPN course book. Because book, I am able to look into these characteristics in a lot more information.

Hypothetically speaking, obstructing the alpha-2 receptors might be useful during weight reduction to maximize the catecholamines like norepinephrine, making more offered to promote beta receptor websites, leading to a greater rate of lipolysis. Also, yohimbine, through its alpha 2-adrenergic receptor villain activity, has been shown to increase levels of norepinephrine in the blood stream.

Galitzky and colleagues observed during their 14-day research study of yohimbine treatment that lipid-mobilizing results were sustained throughout this research study duration. This research collaborated their earlier observations discovered utilizing yohimbine as a lipid-mobilizing agent, in addition to from the research study of Lafontan and colleagues.

Is Yohimbine An Effective Weight Reduction Help?

There are other dietary aids that can result in higher weight reduction, with fewer or no adverse effects.

Kucio and colleagues performed research searching for answers to this very concern. In their research report, titled, “Does yohimbine function as a slimming drug?” they discovered an interesting response. In this study, twenty female subjects were first based on a 3 week 1,000 Calorie daily diet. After this 3 week duration, 10 topics were offered yohimbine and the other 10 were offered a placebo for 3 extra weeks, in addition to the 1000 Calorie each day diet plan.

They discovered that the yohimbine treatment substantially increased weight-loss; 3.55 kgs body weight lost in the yohimbe group versus 2.21 kgs body weight lost in the placebo group. However, there was not a substantial effect on lipolysis observed, nor did treatment with yohimbine delay the stomach emptying rate. Keep in mind that while over 2 pounds more weight was lost by the yohimbine taking group, there were no measurements of where the weight was lost, body fat or muscle, and that these outcomes were observed in inactive females, consuming 1000 Calories each day.

Likewise, there are other dietary help that can result in greater weight loss, with fewer or no side effects. The scientists concluded that further research study is warranted to figure out the applicability of using alpha 2-receptor repressive supplements as extra management in the treatment of obesity.

Waluga and colleagues went on to examine what the combined results of caffeine and yohimbine were on cardiovascular function and rate of weight-loss. To do this they divided twenty-seven healthy females, into three groups of 9. The very first group got only a very low calorie diet (400 Calories daily) and a placebo. The second group received the exact same diet, and caffeine supplement treatment. The 3rd group got the same diet plan, and caffeine treatment utilized in group 2, plus yohimbine.

The treatment lasted for 10 days. At the end of the research study the scientists observed a considerable decrease in body mass in all groups, without any statistical distinction between the groups; Group 1 lost 3.3 kilograms of body weight, group 2 lost 3.5 kgs of body weight, and group 3 lost 3.4 kilograms of body weight. Although no considerable outcomes were seen between the groups, the researchers pointed out that this study was just 10 days long, and that the topics were on a really low calorie diet, which might have distorted any weight loss effects of the supplements, or was too short to differentiate the real results reported by other researchers.

Nevertheless, the main aim of the research study was to identify adverse results of the supplement treatment on the cardiovascular system, and in fact, the researchers did identify that the inclusion of yohimbine together with the caffeine, did evoke some possibly dangerous modifications in the cardiovascular system. They concluded that the addition of yohimbine must be treated with care, and need to be omitted in particular obese individuals with cardiovascular issues. [7]
