However, few reports have been published in relation to the analysis of counterfeit herbal supplements for the detection of synthetic drugs in Iran. Aims: To analyze herbal drugs used as sexual performance enhancer from forensic and analytical toxicology point of view. Methods: Eighty herbal drugs gathered from herbal shops in Bushehr city, Iran were analyzed. High-performance liquid chromatography and gas chromatography/mass spectrometry were used for detecting and identifying the chemical structures of probable active pharmaceutical ingredients as adulterants. Results: Among 80 samples, 23% contained only sildenafil. Three samples contained sildenafil, tramadol, and diazepam in combination with each other reported for the first time. Conclusions: This study substantiates regular analysis of purported herbal drugs is needed for more effective quality control and health promotion.
