Most studies of the biological effects of ginsenosides have been in cell culture or animal models and thus their relevance to human biology is unknown. Effects on the cardiovascular system, the central nervous system, the immune system have been reported, primarily in rodents. Antiproliferative effects have also been described. Many studies suggest that ginsenosides have antioxidant properties. Ginsenosides have been observed to increase internal antioxidant enzymes and act as a free-radical scavenger. Ginsenosides Rg3 and Rh2 have been observed in cell models as having an inhibitory effect on the cell growth of various cancer cells while studies in animal models have suggested that ginsenosides have neuroprotective properties and could be useful in treating neurodegenerative disease such as Alzheimer's and Parkinson's diseases. Two broad mechanisms of action have been suggested for ginsenoside activity, based on their similarity to steroid hormones. They are amphiphilic and may interact with and change the properties of cell membranes. Some ginsenosides have also been shown to be partial agonists of steroid hormone receptors. It is not known how these mechanisms yield the reported biological effects of ginsenosides. The molecules as a class have low bioavailability due to both metabolism and poor intestinal absorption.
