Yohimbe Bark
Yohimbe Bark
Snapshot
Yohimbe Bark is an herbal extract from the West African Pausinystalia johimbe tree, rich in the alkaloid yohimbine, used to support healthy sexual function, energy metabolism, and sympathetic nervous system activity.
What is Yohimbe Bark?
Yohimbe Bark is the dried inner bark of the Pausinystalia johimbe tree. It contains the active compound yohimbine, an alpha‑2 adrenergic receptor antagonist that promotes neurotransmitter release and circulatory dilation.
Where It Comes From
Yohimbe trees are harvested in West and Central Africa. The inner bark is stripped, air‑dried to preserve alkaloid content, and milled into a fine, brownish powder or extracted with alcohol to produce standardized yohimbine extracts.
Key Nutrients & Compounds
Provides yohimbine (typically standardized to 6–8% in extracts), along with other indole alkaloids and tannins that synergize to influence adrenergic and dopaminergic pathways.
Health Benefits
Yohimbe Bark enhances sexual arousal and erectile function by increasing blood flow and nerve sensitivity; supports fat mobilization and energy expenditure through sympathetic stimulation; and may improve mood and mental alertness via central adrenergic activation.
Recommended Dosage
Typical dosing ranges from 5 mg to 15 mg of yohimbine hydrochloride (equivalent to 80–250 mg of bark extract) per day, divided into two or three servings. Start at the lower end to assess tolerance, ideally on an empty stomach.
How to Use It
Take Yohimbe Bark extract capsules standardized for yohimbine with water, 30–60 minutes before intended effect. Avoid taking late in the day to prevent sleep disturbances. Consistent use is not recommended—use situationally.
Who Should Use It?
Adults seeking natural support for mild erectile difficulties, enhanced energy, or fat‑loss adjuncts may benefit. Not recommended for individuals with cardiovascular conditions, high blood pressure, anxiety disorders, or taking stimulants.
Possible Interactions or Cautions
Yohimbe Bark can raise heart rate and blood pressure; avoid in hypertension, heart disease, or anxiety. May interact with MAO inhibitors, SSRIs, stimulant medications, and anticoagulants. Discontinue if adverse effects such as rapid heartbeat, headache, or agitation occur.
Final Thoughts
Yohimbe Bark offers targeted adrenergic stimulation for sexual function and energy, but its narrow safety margin and side‑effect profile require careful dosing and situational use under professional guidance.
