Medical experts in the U.S. have raised alarms over honey products being sold as organic aphrodisiacs that contain dangerously high levels of erectile dysfunction drugs, according to a study published in the journal Molecules.

These products, marketed to boost libido, are being laced with undeclared sildenafil (Viagra) and tadalafil, and sold as food supplements and pastes. Researchers found that doses of these drugs in some honey-based products exceeded the recommended daily maximum for users.

"The adulteration of food or food supplements with PDE-5 inhibitors is extremely dangerous for consumers due to their unknown effectiveness and toxic effects," said Dr. Joanna Wojtacka, who led the study. The study's authors are calling for stricter regulations on these so-called 'aphrodisiac honeys'.

Consumers, particularly men already taking supplements or medications for erectile dysfunction, may be unaware of the hidden drugs in the honey, leading to potentially dangerous interactions. The researchers noted that even for healthy individuals, consuming these contaminated products with alcohol could result in a dangerous drop in blood pressure and loss of consciousness.

"Honey has a reputation of being a wholesome and health-giving natural product so it can be taken advantage of," commented Professor Francis Ratnieks, emeritus professor of apiculture at Sussex University. The products are being advertised on social media and are widely available, posing a significant risk to unsuspecting consumers.
