What the Research Says about Yohimbe
Yohimbine has been evaluated in the management of erectile disorder by means of many placebo-controlled trials. It does appear to have a modest therapeutic benefit, particularly in psychological cases of erectile disorder. Here's one summary of a study: In contract, yohimbe has not been studied much.
   A 1977 German double-blind, placebo-controlled clinical trial of yohimbine hydrochloride included 86 patients with erectile dysfunction and without clearly detectable organic or psychologic causes. Yohimbine was administered orally in a dosage of 30 mg a day (two 5 mg tablets three times daily) for eight weeks. Patients were seen for follow-up after four weeks' treatment, and for a final visit after eight weeks. Efficacy evaluation was based on both subjective and objective criteria. Subjective criteria included improvement in sexual desire, sexual satisfaction, frequency of sexual contacts, and quality of erection (penile rigidity) during sexual contact/intercourse. Objective criteria of outcome were based on improvement in penile rigidity determined by use of polysomnography in the sleep laboratory. Overall Yohimbine was found significantly more effective than placebo in terms of response rate: 71 vs 45%. Yohimbine was well-tolerated: Only 7% of patients rated tolerability fair or poor, and most adverse experiences were mild. There was no serious adverse event.

Women and Yohimbe supplement use
A study conducted at the University of Texas at Austin, Texas examined the effects of arginine combined with yohimbine on sexual arousal in postmenopausal women with Female Sexual Arousal Disorder. Twenty-four women participated in three treatment sessions in which self-report and vaginal sexual responses to erotic stimuli were measured following treatment with either L-Arginine (6 g) plus yohimbine (6 mg), yohimbine alone (6 mg), or placebo, using a randomized, double-blind, three-way cross-over design. Sexual responses were measured at approximately 60 minutes postdrug administration. The combined oral administration of L-arginine and yohimbine substantially increased vaginal pulse amplitude responses to the erotic film at 60 min postdrug administration compared with placebo. The vaginal response was measured with an instrument called a vaginal photoplethysmograph.

Yohimbe Mechanism of Action
Yohimbine acts through the nervous system to increase blood flow to the genital region. Although many pharmacological properties of yohimbine have been described, at the plasma concentration attained at recommended dosages in humans the predominant activity is antagonism of alpha 2-adrenoceptors.

Yohimbe Side effects and Cautions
Yohimbe should be used cautiously by anyone with a medical condition, particularly those with hypertension, heart disease, diabetes, or those taking medicines, particularly tranquilizers, antidepressants, sedatives, antihistamines, amphetamines or other stimulants, including caffeine. Yohimbine induces noradrenaline secretion. Some of the side effects of yohimbe include anxiety, changes in blood pressure, heart rate increase or palpitations, dizziness, headache, visual disturbances, nausea or abdominal cramps, increased body temperature and sweating.
   Since high doses of yohimbe may cause confusion and disorientation, it should not be taken while operating machinery, driving, or performing hazardous activities.

Yohimbe Questions
Q. I am a 73 year-old physician involved in the newer subspecialty of Travel Medicine. I am in excellent health and still have an active sex life. I have had some off and on problems with erectile dysfunction. Over a period of perhaps 10 years, I have had occasion to take Yohimbine in one blend or another, always with somewhat unpleasant sensations. The most recent proprietary blend that I tried was a half dose serving of one tablet of Stamina-Rx. (550mg?). Stamina Rx was shown to contain both yohimbine and yohimbe extract. I did have a fairly good response, but with the same side effects as before. The most prominent is a feeling of cold chills up and down my spine and generally over my body. It is most unpleasant and lasts for 8 to 12 hours. I have not seen this indicated in several lists of yohimbe side effects. I am quite interested in Passion Rx and have ordered it. However I definitely do not want the blend with the yohimbe. Do you have any recommendations or thoughts on this matter?
   A. Yohimbe works well in the right dosage with less side effects, sometimes it takes trial and error to find the least amount of yohimbe that works with the least amount of side effects. In the case of Stamina Rx, perhaps you can try a third of a capsule.

Q. In literature here, you say people over 65 should not take yohimbe? I am 79 years old, can't I take a small amount of yohimbe? I have E.D. as you probably guessed and have not had sex for about 5 years!
   A.  We are not in a position to give individual advice to users of supplements. One person your age could handle a small amount of yohimbe well, another person could have a yohimbe side effect.  Your doctor can read the yohimbe information and make a decision based on your unique situation.

Q. Is it possible that yohimbe side effects include headaches or migraines?
   A. Yes, yohimbe can cause headaches in some users.

Q. I have a some questions regarding Yohimbe: First will the Yohimbe in Passion Rx with yohimbe product disrupt sleep? And secondly, I have read that genuine Yohimbe in significant amounts is next to impossible to acquire from herbal supplements typically sold in the West. (The same has been said about Tongkat Ali) I would appreciate your comment on this.
   A. When a capsule of Passion Rx with yohimbe is taken in the morning, it should be out of the system by bedtime and one can sleep well. Yohimbe by itself is usually out of the system within a few hours unless a high dose is taken. Enough yohimbine is found in a yohimbe product to be effective. Same with tongkat ali, the products over the counter are potent.

Q. What other 31 alkaloids are in yohimbe bark besides yohimbine, and what do they do?
   A. We have not seen any specific or substantial research regarding the different alkaloids in yohimbe.

Q. My question is in regards to the Yohimbe supplements. I intend to take a sexual enhancement pill that does not contain yohimbe along with a yohimbe supplement. I recently purchased a 450mg pill with 2% Yohimbine or 9mg. Is this the right dosage?
   A. The dosage of yohimbe that is effective while causing few side effects varies between individuals and the quality of the product and raw material source. A safe way is to start with a small portion of a yohimbe supplement capsule by itself to learn how it works before even thinking of combining it. Sexual herbs do have side effects when high dosages are taken.

Q. What is the dosage of yohimbe is in Passion Rx. Is it recommended as a "single" use product as we would not like to be taking it regularly. if so, what is the dosage and recommended time to take prior to sexual activity?
  A. In order for yohimbe to have a quick effect within a couple of hours, one has to take a high dose and this leads to unpleasant or serious yohimbe side effects such as rapid heart beat, increased body temperature, sweating, restlessness, and stomach upset. Passion Rx with yohimbe has a smaller amount of yohimbe to avoid these side effects. But, it does not work right away. The benefits are usually noted on the second, third, or fourth day. It is taken in the morning before breakfast for two days in a row and none the third day, and then resumed the fourth day as needed. Once the effects begin, they last several days even if you don't take a capsule. The low dose and gradual enhancement are meant to minimize side effects that are common with high dose yohimbe use. This is a proprietary blend and the dosage of the ingredients cannot be revealed to avoid competitors from copying the successful formula.

Q. I have a question about the on-going effects of yohimbe: If I use it daily, will my body develop a tolerance for it and respond less (sexually libido wise)? Alternately, will I respond more sensitively to it, as if it had a cumulative effect?
I seem to have varied and unpredictable responses to this product as I use Passion Rx. Thank you for Passion Rx, as it is very nice. Thank you for any helpful information.
   A. This is a good question. With many sexual herbs, tolerance can develop. This is less so with yohimbe, it seems to work better, at least for a while, when it is used regularly. There could also be differences in response between people and different dosages and frequency of use could also make a difference. As to Passion Rx with yohimbe, it is best used no more than 3 or 4 days a week since it has additional herbs that work better when breaks are taken.

Q. is it possible to tell me how much yohimbe (mg's) is in Passion Rx with yohimbe?
   A. We cannot say exactly, but it is not too much to cause the yohimbe side effects that people get when they take a yohimbe supplement.

Q. Q. I'm a 70 year old male with glaucoma and have been thinking about purchasing Passion Rx with yohimbe. However, I have read a few articles that indicate that yohimbe should not be taken by an individual with glaucoma. I am currently taking Prostate Power Rx and Eyesight Rx.
   A. We suggest not using Passion Rx, with or without yohimbe, the same day as Eyesight Rx. These supplements are potent, particularly Eyesight Rx and Passion Rx, and therefore it is best to not take them the same day. For those over the age of 60, we suggest not using more than half a capsule of Passion Rx 4 days a week. Same with Eyesight Rx, we suggest not using more than half a tablet of Eyesight Rx more than 4 days a week.
