Usage: 6-10 teaspoons of shaved bark are boiled 10 minutes in 1 pt. water, strained and sipped slowly. Addition of 500 mg of vitamin C per cup makes it take effect more quickly and potently (probably by forming easily assimilated ascorbates of the alkaloids). Bark can also be smoked. Yohimbine hydrochloride, a refined powder version, can also be snuffed. Also available at many health/herb stores is a liquid extract.
Effects: Called "the most potent aphrodisiac known" and "the only true aphrodisiac". Whether aphrodisiacs exist outside of mythology or not is a topic for debate, as is the definition of "aphrodisiac". Anyway, first effects after 30 minutes (sooner with vitamin C) consist of warm, pleasant spinal shivers, followed by psychic stimulation, heightening of emotional and sexual feelings, mild perceptual changes without hallucinations, sometimes spontaneous erections. Some experience nausea during first 30 minutes. Sexual activity is especially pleasurable. According to one source "Bantu orgies have been known to last over a week" [Ed: don't they get hungry?]. Total experience lasts 2-4 hours, however, several experiences lasting up to 24 hours have been reported. Aftereffects include pleasant, relaxed feelings with no hangover, but difficulty sleeping for a few hours (probably largely due to the increased mental activity).
Since they sell the stuff in health food stores and I'm not sure what it's legitimate uses are, I'm willing to admit that I've tried it. My experience was worth repeating. This of course constitutes no endorsement on my part of illegal or legal drugs or of the use of yohimbe for any reason at all.
I ground about 7 teaspoons of shaved bark in a spice grinder (fresh grinding seems to help with release of the active ingredients) and then boiled it in a pint of water for about 10 minutes. The stuff absorbs a lot of water. Also, when freshly ground, you get some FINE FINE FINE particles. It took me a good 15 minutes to filter the stuff out through coffee filters (had to use a bunch of filters cuz it clogged them up so bad). The resulting brew was one of the top three worst things I've ever tasted in my life (the other two being calamus root and an abortive attempt at a kava kava concoction). It tasted kind of like bile. You can kill the taste if you put enough honey in the tea, but the aftertaste never goes away. As soon as you swallow it creeps up your throat; really gross. The fact that the stuff should be sipped slowly makes this even worse. I would recommend finding a REAL strong chaser, like pure lemon juice or maybe a mint leaf--something that obliterates all other taste in your mouth when you eat/drink/chew it, yet is tolerably pleasant tasting. I would swig/chew this chaser after every sip of yohimbe tea.
WARNING: The active ingredients in yohimbe are MAO inhibitors.
MAO stands for MonoAmine Oxidase, an enzyme that breaks down certain amines and renders them ineffective. MAO inhibitors, then, are substances that interfere with the action of monoamine oxidase, leaving the amines intact. If the amines in question are dangerous, they can cause nasty--even deadly--side effects. Furthermore, it is dangerous to combine MAO inhibitors. If you are taking a prescription drug that is an MAO inhibitor, like prozac or most anti-depressants, avoid using any substance listed as an MAO inhibitor here.
The bottom line is this: when using an MAO inhibiting drug, don't ingest anything that contains potentially dangerous amines, or any other MAO inhibitor. If a substance is listed as an MAO inhibitor here, it may be dangerous when used in combination with any of the following substances:
amphetamines (even diet pills)
wild fennel oil
coffee (or any substance that contains large amounts of caffeine)
any tyrosine-containing food
any other MAO inhibitor
The sexual effects lasted about 4 hours (only cuz I was getting tired :^); the speedy effects decreased earlier than that, but I couldn't sleep at all that night (even when I was ready to), and I'm sure it was because of the yohimbe.
I also recently tried the yohimbe extract that they sell in health food stores. The stuff costs about $7/oz. It comes in one ounce bottles with screw-on eye-dropper caps. Recommended dose on the bottle is 3-20 drops up to three times a day. First time I tried it I took 35 drops with absolutely no effects. Recently, I took 100 drops mixed in orange juice. The stuff is tasteless in minute quantities, but at 100 drops/~8 oz. of OJ, it added a mildly bitter taste. Not too bad, tho--1000x better than the tea. Anyway, it didn't do anything, so I took another 50 drops, then another 50, and still no effects whatsoever. I wonder if the extract is even active.
I would advise yohimbe experimenters to use the tea form, and start out with 4 or five teaspoons of fresh ground bark, as the effects of 7 teaspoons were quite pronounced in me, and I am a 200 lb. male with a high tolerance for everything.
Interaction precautions: MAO inhibitor.
Active Constituents: Yohimbine, yohimbiline, ajmaline. (Note that yohimBE is the plant; yohimBINE is one of the chemical principles found in the plant.)
