Last 06 July, Health Canada announced the withdrawal from the market of a sexual enhancement product named Lighting Rod because it apparently contains a hidden ingredient that could potentially harm people taking it.
What is this hidden ingredient and in what way is it harmful? According to Health Canada, the ingredient is hydroxythiohomosildenafil, a synthetic drug similar to sildenafil (which is the main ingredient of Viagra). How does this substance harm a consumer? Well, it interacts with nitrates found in prescription drugs and lowers a person’s blood pressure to dangerous levels. Other side effects include include headache, facial flushing, indigestion, dizziness, abnormal vision and hearing loss.
Now what makes products such as Lighting Rod more of a health risk is the fact that their manufacturers tend to not disclose in their product labels that their “health supplement” contains this ingredient with adverse health effects.
