Use a teaspoon of cayenne powder in a glass of warm water, drink it down. I don't have that problem, despite taking both NAC and Quercetin, so can't confirm that it works, but then I put Cayenne powder in my food on a regular basis. Cayenne powder has been used for probably centuries to stop bleeding. Midwives use it post-birth, when necessary. https://www.earthclinic.com/cures/bloody-nose-treatment.html Above is my favorite home-remedy site.
