Yohimbe is a natural herbal supplement that is strongly associated with anti-aging effects. Yohimbe has a long history of use in Western Africa, and is still widely used there today, to treat a variety of sexual disorders, including low libido and erectile dysfunction.
Medically, yohimbine is a pre-synaptic alpha-2-adrenergic blocking agent, which is capable of increasing sympathetic nervous system activity, thus resulting in increased amounts of epinephrine (also known as adrenaline) and norepinephrine in the blood stream.
The main effects epinephrine and norepinephrine have on the body include increasing blood pressure and heart rate. Yohimbe is also often used for weight loss, although the evidence supporting this claim is inconclusive.
