Dang Qui (Angelica root) may be used alone and conjunction with other herbs in reduced blood glucose of patient with diabetes new study suggested.
According to the 2011 statistic from National Diabetes InformationClearinghouse (NDIC), among U.S. residents ages 65 years and older, 10.9 million, or 26.9 percent, had diabetes in 2010, about 215,000 people younger than 20 years had diabetes—type 1 or type 2—in the United States in 2010 and approximately, 1.9 million people ages 20 years or older were newly diagnosed with diabetes in 2010 in the United States.
Beside acting as a queen herb in balancing the hormones in women for a normal menstrual cycle and menstruation, Dang Qui also used in traditional Chinese medicine to treat gynecological ailments, fatigue, mild anemia and high blood pressure. It has analgesic, anti-inflammatory, etc.(1)
Dang Gui Bu Xue Tang (DBT), an aqueous extract of Radix Astragali and Radix Angelica sinensis of Chinese herbal formula, showed to significantly alleviate the hyperglycemia but made no influence on plasma lipid profiles nor weight gain in fructose chow-fed rats when applied alone, through increased post-receptor insulin signaling(2). Together with Panax notoginseng (RRP), the extract showed to reverse high glucose-induced inhibition of endothelial cell migration and proliferation, through decreased the expression of inflammatory factors(3).
Decursin, an active compound isolated from Angelica gigas, also showed a significantly reduced the secretion of HFD-induced adipocytokines such as leptin, resistin, IL-6 and MCP-1 associated to diabetes and obesity(4)
Angelica Keiskei, another member of Angelica improved insulin resistance in diabetes of rats induced by streptozotocin with intraperitoeal injection as well as with high-fat diet feeding through upregulation of the mRNA expression levels of PI3K and Akt(5).
Dr, Zhao Y. and the research team at the Medical College of Qingdao University also in the study of the effect of Angelica Keiskei in diabetes told PubMed ” Angelica keiskei chalcone (the extract) may increase the expression levels of Glut2 in liver and Glut4 in skeletal muscle cells, decrease fasting blood glucose and insulin of type 2 diabetic rats and improve their insulin resistance condition”(6).
Unfortunately, oral administration of angelica have linked to proliferation of the breast cancer for women with history of breast cancer and gene mutation Her-2(7)(8).
Taken altogether, Dang Qui may be effective in reduced glucose level of patients with type II diabetes and can be considered for prevention of diabetic complications. Due to its conflict results in breast cancer studies, it is advice that women with mutation gene Her or with history of breast cancer should consult their Doctor & Related field specialist before applying.
