Yohimbe extract is derived from an evergreen tree that originates in parts of Africa, according to Medline Plus. Yohimbe supplements are used by both men and women for various reasons. Consult a health-care provider before taking yohimbe supplements.
Identification
Yohimbe supplements are available in variety of forms, including capsules, tablets and tea extracts. Medline Plus reports that yohimbe contains an active chemical called yohimbine, although yohimbe supplements might contain only small amounts of the yohimbine extract, according to the National Center for Complementary and Alternative Medicine, or NCCAM.
Uses
Yohimbe supplements are most commonly used by people with erectile dysfunction to arouse sexual excitement, according to Medline Plus. In addition to improving sexual performance, male and female athletes also use yohimbe supplements to promote performance. Medline Plus reports that yohimbe supplements also are used in hopes of promoting weight loss and preventing physical exhaustion.
Effects
The NCCAM reports that there is currently no research supporting the effectiveness of yohimbe for treating any health conditions. A systemic review titled "Yohimbe for erectile dysfunction" published in the "Journal of Urology" evaluated the effectiveness of yohimbe and found that yohimbe provided superior benefits for patients with erectile dysfunction when compared with a placebo. The review concluded that yohimbe might be a reasonable therapeutic option for erectile dysfunction. Medline Plus reports that yohimbine, the active ingredient in yohimbe bark, also might improve sexual problems caused by certain prescription drugs used for depression.
Interactions
The NCCAM reports that yohimbe should not be taken with MAO inhibitors. People with psychiatric conditions taking tricyclic antidepressants and phenothizaines also should avoid yohimbe supplements. The active ingredients in yohimbe might increase the effects of these medications, according to Medline Plus. Yohimbe use also might be contraindicated in people diagnosed with anxiety, depression, high blood pressure, kidney disease and heart disease. Consult with your health-care provider before combining yohimbe supplements with any prescription medication.
Side Effects
According to research reported by Medline Plus, oral yohimbe use might be unsafe. Yohimbe supplements have been linked to various side effects such as irregular heart beat, heart attack, seizures and kidney failures. Large doses of yohimbe might be fatal if taken over long periods, reports the NCCAM. Other reported side effects include nausea, vomiting and sleeplessness.
