SexRx: Yohimbine and Your Sex Life
En Español (Spanish Version)


Yohimbine is an alkaloid that is found in the bark of a West African evergreen tree—the yohimbe tree. Yohimbine might help treat impotence that can be caused by a variety of factors, although it comes with many risks.

Commonly Used Product Names
  • Yohimbine hydrochloric acid (HCL)—a prescription drug in a tablet
  • Yohimbe bark—available in the following forms:
    • Capsule
    • Concentrated drops
    • Decoction (an extract obtained from boiling)
    • Tablet
    • Tea
    • Tincture
Yohimbe bark is often not standardized based on yohimbine content. Therefore, it is a less reliable source than the drug form.

Sexual Effects
Yohimbine has a long history of being used as an aphrodisiac. Some studies have suggested that it may have the following pro-sexual effects:

  • Helps to obtain and maintain erection
  • Enhances quality of erection

Cautions
Medications
