An interesting study in Scotsman shows that Primrose, borage and black currant seed oil reduces the risk of breast cancer by regulating the gene protein that causes the breast tumor. Research leader Professor Ruth Lupu, of Northwestern University, in Evanston, Illinois has further expanded his research to compare both Herceptin and gamma-linolenic acid (GLA), the compound found in the mentioned oils and found that while the former neutralises molecules of the gene protein found on the surface of cancer cells, the latter regulate it from the source. However, GLA has an advantage over Herceptin in treating Her-2/neu-positive cancer patients.
Though the clinical trials are going on there is no harm in taking evening primrose oil as reports say that it does not interfere with the normal cells and being herbal it has no side effects.
