What does yohimbine mean?
Yohimbine is a naturally occurring indole alkaloid associated with the bark of the yohimbe tree, a West African plant long used in traditional medicine. Chemically, it acts principally as an alpha-2 adrenergic receptor antagonist and is studied for its effects on the nervous system, blood pressure, and neurotransmitter release. It has also been marketed as a supplement for sexual function, especially for erectile dysfunction, but that use is controversial. Regulatory authorities have warned that yohimbine can produce serious adverse effects, including changes in blood pressure, heart rate, anxiety, and other potentially dangerous reactions. In general writing, the word is therefore most familiar in medical research, pharmacology, public-health warnings, and discussions of the yohimbe trade. It should not be confused with yohimbe itself: yohimbe names the tree and its bark, while yohimbine is a particular purified chemical constituent associated with that plant.
nounAn indole alkaloid and alpha-2 adrenergic receptor antagonist obtained from the bark of the African yohimbe tree and also produced synthetically. It has been used experimentally in medicine and marketed as a supplement for sexual function, although it can cause serious adverse effects and interactions.
- An indole alkaloid found in yohimbe bark, used as a pharmacological research agent and as a substance marketed for sexual function.
"The researcher administered yohimbine before the controlled neurological experiment."
"The laboratory compared the effects of yohimbine on noradrenaline release."
"Health authorities have warned consumers about the risks of taking yohimbine supplements."
The plural is possible but uncommon in technical writing, where the compound is normally discussed in the singular or as a mass noun.
"The encyclopedia includes entries for several yohimbines and their related compounds."
Yohimbine is the best-known chemical in yohimbe bark—and also one of the clearest examples of why a historic reputation is not the same as modern medical approval.

Etymology of yohimbine
The name derives from yohimbe, the West African name of the tree whose bark supplies the compound, together with the chemical suffix -ine used in the names of many alkaloids. Early twentieth-century pharmacological work on yohimbe distinguished yohimbine as a specific constituent of the bark. Related chemical terminology includes yohimbic and yohimbate, reflecting the same yohimbe-based naming tradition.
How yohimbine is actually used
This is primarily a scientific, medical, and pharmacological term rather than ordinary vocabulary. In consumer contexts it is often discussed in connection with sexual-function supplements, but such uses carry risks of adverse cardiovascular and psychiatric effects.
Easily confused with yohimbine
Yohimbe is the West African tree and the bark used in traditional preparations, whereas yohimbine is a specific alkaloid chemically derived from that bark.
