Top Medical Research Studies

We examined how quercetin, a natural compound, can help alleviate chronic cough by targeting P2X3 receptors, which are involved in cough reflexes. The study involved testing its effects on male mice and guinea pigs.

Results showed that quercetin effectively modulated these receptors without causing adverse taste effects, unlike other drugs like gefapixant. This potential opens up new avenues for treating chronic cough without unpleasant side effects.

An excellent complex for allergies and viral diseases. It helped to remove my chronic cough. Additionally, we give it to children at the onset of colds, and it helps them recover faster.

I have chronic sinusitis and experience infections every few months. After taking this supplement for several weeks, I’ve noticed an improvement in my symptoms. I believe it's worth the price to continue using it. I highly recommend it to anyone suffering from sinusitis!
