1. Antioxidant: Quercetin (the core active component in Sophora japonica extract) has strong free radical-scavenging ability, which reduces oxidative damage to cells and delays tissue aging.
2. Anti-inflammatory: It inhibits the release of pro-inflammatory mediators (e.g., histamine, prostaglandins), relieving inflammatory responses in the body.
3. Vascular Protection: It helps improve blood vessel elasticity, reduce capillary permeability, and support cardiovascular health.
4. Antibacterial & Antiviral: It exhibits inhibitory effects on certain pathogenic bacteria and viruses (e.g., influenza virus) by disrupting microbial cell structures.
5. Antihistamine: It alleviates allergic reactions (e.g., hay fever, skin itching) by blocking histamine receptors.
