Yohimbe vitamin

Answered according to Hanafi Fiqh by DarulUloomTT.org

Q. Have you ever heard of a vitamin called Yohimbe? If so, is it halaal?

A. Yohimbe is derived from the bark of the Yohimbine tree. It is halaal except that some companies sell the product in a gelatin capsule. This would not be permissible to consume. It would be permissible to use in tablet form. Please consult your doctor before using these types of supplements.
