Yohimbe extract 8% refers to an extract derived from the bark of the Yohimbe tree (Pausinystalia johimbe) that contains 8% of the active compound yohimbine. Yohimbine is a chemical compound that acts as an alpha-2 adrenergic receptor antagonist, which can lead to increased sympathetic nervous system activity and decreased fat synthesis in the body.
As a result, yohimbe extract is often used as a weight loss supplement, as well as to improve athletic performance and enhance sexual function in men. It is also sometimes used as a natural remedy for depression and anxiety.
However, it is important to note that yohimbine can cause side effects such as increased heart rate and blood pressure, anxiety, and gastrointestinal distress, and should be used with caution and under the guidance of a healthcare professional. Additionally, it may interact with certain medications, such as those used to treat high blood pressure or anxiety.
