Quercetin is found in citrus fruits, onions and buckwheat and is known for its anti-inflammatory properties. Now researchers at Universitätsklinikum Erlangen at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) have investigated how the plant compound could help treat lung cancer. In the lab, experiments showed that quercetin slows the division of lung cancer cells and almost completely stops their migration. The results have appeared in the journal Cell Death Discovery.
