The water extract of dong quai stimulated the growth of MCF-7 cells, possibly dependent of weak estrogen-agonistic activity, and augmented the BT-20 cell proliferation independent of estrogen receptor-mediated pathway. (當歸的水萃取物會刺激MCF-7細胞生長,有可能是來自於它的弱雌激素協同活性,也會經由雌激素受體媒介的路徑促進BT-20細胞的增殖。)The present study provides data regarding the estrogen-like activity of dong quai, which might assist in decision making on herbal therapy use by women at risk for both estrogen-sensitive and insensitive breast cancer. (近代研究提供有關當歸類雌激素活性的數據,可能提供當中草藥療法要使用於具有雌激素敏感或不敏感乳癌風險的婦女時的評估及考慮。)Because of the lack of clinical data demonstrating the potential side effects of dong quai, its use in herbal preparations for the treatment of peri- or postmenopausal symptoms, especially in women with breast cancer, warrants caution pending further study. (由於缺乏臨床上數據可證明當歸的潛在副作用,當他的生藥製劑使用於治療停經前後症狀,特別是用於那些有乳癌的女性身上時,需要謹慎並獲得授權以進行進一步的研究。)
You should not drink the essential oil of dong quai because it has a small amount of cancer-causing substances(你不應該飲用當歸精油,因為它含有少量會致癌的物質。).People who have chronic diarrhea or abdominal bloating should not use dong quai(有慢性腹瀉或腹脹的人不應該使用當歸。).People who are at risk of hormone-related cancers, including breast, ovarian, and uterine cancers, should not take dong quai because researchers are not sure if it acts like estrogen in the body. (有罹患賀爾蒙相關癌症風險包括乳癌、卵巢癌、子宮頸癌的人不應服用當歸,因為研究無法確定當歸在體內是否有類似雌激素的作用。)
