Yohimbine HCL CAS:65-19-0

Yohimbine is an indole alkaloid derived from the bark of the Pausinystalia yohimbe tree in Central Africa. It is a veterinary drug used to reverse sedation in dogs and deer. Yohimbine has been studied as a potential treatment for erectile dysfunction but there is insufficient evidence to rate its effectiveness. Extracts from yohimbe have been marketed as dietary supplements for improving sexual function.

Yohimbine is a pre-synaptic alpha 2-adrenergic blocking agent. The exact mechanism for its use in impotence has not been fully elucidated. Vendar, yohimbine may exert its beneficial effect on erectile ability through blockade of central alpha 2-adrenergic receptors producing an increase in sympathetic drive secondary to an increase in norepinephrine release and in firing rate of cells in the brain noradrenergic nuclei. Yohimbine-mediated norepinephrine release at the level of the corporeal tissues may also be involved. In addition, beneficial effects may involve other neurotransmitters such as dopamine and serotonin and cholinergic receptors.

Yohimbine is a drug used in veterinary medicine to reverse the effects of xylazine in dogs and deer. Yohimbe extracts, which contain yohimbine, have been used in traditional medicine and marketed as dietary supplements.
Yohimbe is taken by mouth arouse sexual excitement, for erectile dysfunction (ED), sexual problems caused by medications for depression called selective-serotonin reuptake inhibitors, and general sexual problems in both men and women. It is also used for athletic performance, weight loss, exhaustion, chest pain, high blood pressure, low blood pressure that occurs when standing up, diabetic nerve pain, and for depression along with certain other medications.

Yohimbe contains a chemical called yohimbine which can increase blood flow and nerve impulses to the penis or vagina. It also helps counteract the sexual side effects of certain medications used for depression.
