Pterostilbene Introduction
Pterostilbene("3,5-Dimethoxy-4'-hydroxystilbene;4-[(1E)-2-(3,5-Dimethoxyphenyl)ethenyl]phenol, Pterocarpus marsupium) is a chemical component found in purple sandalwood, but scientists have also discovered its presence in other plants. However, because it was first discovered in purple sandalwood, it was named Pterostilbene. Pterostilbene is a white or almost white powder crystal with rich medicinal value. It belongs to the antifungal active ingredient in dragon's blood products and has certain effects on the treatment of cancer, hypertension, and hyperlipidemia. Recently, researchers have mastered the industrial synthesis method of Pterostilbene.

Pterostilbene Function
1) Metabolic disorders.
Preclinical studies have shown that Pterostilbene can increase insulin sensitivity, lower blood glucose levels, and promote weight loss in obese and type 2 diabetic animals. These effects have been attributed to Astragalus' ability to regulate cellular energy metabolism and reduce inflammation, both of which have been linked to the development of metabolic disorders.
2) Cardiovascular Health.
Astragalus purpureus has shown promise in improving cardiovascular health through its antioxidant, anti-inflammatory and lipid-lowering properties. In animal studies, Astragalus purpureus has been found to reduce atherosclerotic plaque formation, improve endothelial function, and lower blood pressure. These effects may help reduce the risk of cardiovascular diseases such as heart attack and stroke
3) Neurological disorders.
Emerging evidence suggests that astragalus may have neuroprotective effects and has potential applications in the management of neurological disorders such as Alzheimer's disease and Parkinson's disease. Pterostilbene powder has been shown to inhibit the formation of amyloid B plaques, a hallmark of Alzheimer's disease, and may prevent neuronal damage caused by oxidative stress.
4) Pruritus.
Pterosilbene has demonstrated anti-cancer properties in various in vitro and in vivo studies. It has been found to inhibit the growth and proliferation of cancer cells, induce apoptosis, and inhibit angiogenesis (the formation of new blood vessels that support tumor growth). These effects have been observed in various types of cancer, including breast, colon and other types of disease.
