Yohimbe:

Yohimbe comes from the bark of a tropical African tree (Corynanthe johimbe), and is typically ground into a powder and ingested in capsule form.

It supposedly works fairly well as an aphrodisiac, mostly due to it’s causing a slight tingling sensation in the genitals.

Now, the chemical in yohimbe bark that really packs the punch is called Yohimbine. There is relatively little pure Yohimbine in ground up Yohimbe bark (less than 10%, in fact, and even that amount varies depending on how it was preserved) but it is the chemical we are interested in.

Why?

Because Yohimbine apparently increases blood flow to the genital area, both relaxing and widening the blood vessels to enhance circulation. Coupled with the light tingling sensation, it is a gentle boost to natural stimulation.

Yohimbine also works as a mild nervous system stimulant and enhances your breathing capability, so it allows you to have sex longer without as much body and muscle fatigue.

Now for the downside:

It may block certain neurotransmitters, making this a bad choice for manic-depressives or people on mood stabilizers. (Unfortunately, this includes me. I only took the capsules for a few days, and didn’t notice a difference, but still….)

Also, it may help relax the uterus, which is bad if you’re pregnant (possible miscarriages, and such) But good for female orgasms.

I tried it for a couple of days, as did one of my male volunteers. The consensus was that it helped speed up foreplay and sexual readiness, but wasn’t a substitute for it. You can walk around feeling a tiny bit warm and tingly (more so for my male volunteer than for me) but it’s not a “take me! take me now, you love machine!” in pill form.
