Good for stomach ulcers
It’s been shown that quercetin can help to heal stomach ulcers. This is likely because it has anti-inflammatory and antioxidant properties. It’s thought that quercetin may help to reduce the inflammation in the lining of the stomach. It may also help to protect the lining of the stomach from damage caused by Helicobacter pylori bacteria.
