Reported side effects of Sang Ji Sheng include: dizziness, giddiness, anorexia, abdominal distention, and xerostomia, etc. (5)


Anti-lipid and anti-atherosclerosis effects

Experiments show that Sang Ji Sheng can not only lower lipid content, it can also increase the activity of SOD, help get rid of superoxide free radicals, decrease superoxide lipid, and prevent and treat atherosclerosis. (6) Moreover, research shows that Sang Ji Sheng is conducive to eliminating aortic foam cells in rabbits fed with fat-rich diet, inhibits the proliferation of smooth muscle cells and fibrous tissues, promotes structural recovery in smooth muscle cells, and enhances intracellular lipid metabolism, strengthens the barrier function of aorta endothelial cells.

Effects on enkephalin

Rats with desoxycorticosterone acetate-induced hypertension invariably have elevated levels of methyl enkephalin (MEK) and leucine enkephalin (LEK) in the brain stem and striate body, and a sagged level of MEK in the hypothalamus. As the disease progresses, the blood pressure keeps rising. Even after the initial factors that triggered the hypertension (i.e., DOCA and saline water) are removed, the central enkephalin system remains activated, and the blood pressure remains artificially high. Experiments show that under similar conditions, a treatment with Hu Ji Sheng makes all the difference: the blood pressure and enkephalin level in each region of the brain recovers, MEK and LEK levels in the brain stem and striate body decrease, MEK in the hypothalamus increases, suggesting that Hu Ji Xheng has bi-directional effect of regulating abnormal changes in central enkephalin.

Effects on the heart

Sang Ji Sheng decoction (5.10g/ml) has significant inhibitory effect on chloroform-induced ventricular fibrillation in mice. (9) Bei Ji Sheng is shown to counteract cedilanid-induced arrhythmia, (10) and to repair damages inflicted by experimental myocardiac infarction in dogs. (11)
