Quercetin supplements may be beneficial for people who suffer from allergies or asthma because they reduce histamine release from mast cells. This means that quercetin could potentially help to relieve symptoms of both conditions, such as sneezing, itchy eyes and runny nose.

In addition, quercetin appears to help treat hay fever by preventing the release of histamine during an allergic reaction and reducing inflammation caused by the release of pro-inflammatory cytokines (messengers).

Quercetin supplements may also help prevent cancer by interfering with signal pathways involved in cell growth and survival. This means quercetin may slow down cancer cell growth and stop tumors from spreading around the body (metastasizing).
