Yohimbin is a popular alkaloid compound that is derived from the bark of the Pausinystalia Yohimbe tree. However, during the production process of Yohimbin, impurities may be formed as a result of chemical reactions or contamination. These impurities can affect the purity, potency, and safety of the drug, and may lead to adverse effects or reduced efficacy. Therefore, it is important to monitor and control the level of impurities in Yohimbin to ensure its quality and effectiveness.
