Contraindicated for patients with excessive dampness, pathogenic factors of the excess type, and or food retention.

Administration of Shan Yao decoction can lower the blood pressure of healthy mice. It has both preventive and therapeutic effects alloxan-induced diabetes induced in mice.(9)

Shan Yao polysaccharides, injected i.p., can promote the activity of glutathione peroxidase, catalase, peroxide dismutase and cerebral Na/K-ATPase, decrease the activity of monoamine oxidase and the contents of lipids peroxide and lipofuscin.(10)

Experiments show that Shao Yao polysaccharides can significantly promote the cellular and humoral immune functions in mice.(11)

Experiments show that Shan Yao extract has anti-fatigue effects and can enhance endurance and contractility of muscles.(12)

One experiment randomly divided mice into six groups and five of them were fed decoctions of the following herbs, respectively: control group (stilled water), Radix Rehmanniae Praeparata, Flos Chrysanthemi, Rhizoma Dioscoreae, Radix Achyranthis Bidentatae, and a mix of all four herbs. The sixth group was fed distilled water and served as the comparison group. The herb decoctions were fed to the subjects twice a day, 0.15ml each time. Forty days later, the mice were killed, and their brains removed to determine the activity of MAO in the mitochondria. The results showed that, the MAO activity levels of the Rhizoma Dioscoreae and Radix Achyranthis Bidentatae groups were significantly lower than that of the comparison group (P£¼0.05), and that the difference between the MAO activity of the mix group and that of the comparison group was even more significant (P<0.01).(13)

Administered at high dosages, Shao Yao can significantly increase the NE and 5-HT levels in the brains of reserpine-treated mice, suggesting that the herb promotes the synthesis of mono amino transmitters in animals treated with reserpine.(14)

Shan Yao can increase gastric secretion and gastric acidity. It has anti-diarrhea effects in mice wtih spleen deficiency. It can increase cold tolerance, but does not significantly affect the activity of pepsin in rats.(15)
