  schema:description "Evening primrose oil is taken for breast pain, hot flushes and skin problems. Evidence is mixed for each, and in cancer the few trials are small: one in liver cancer showed no effect on the tumour or survival. It can increase bleeding with blood thinners, and some products add plant oestrogens, so check the label if your cancer is hormone-sensitive."@en ;
