1. Antioxidant Activity: Dihydromyricetin (DHM) in vine tea extract has strong antioxidant capacity, which can scavenge free radicals (such as superoxide anion and hydroxyl radical) in the body, reduce oxidative stress damage to cells, and delay the aging process.
2. Liver Protection: It can protect liver cells from damage caused by alcohol, drugs, and other toxic substances. It promotes the metabolism of alcohol in the liver, reduces the accumulation of acetaldehyde (a toxic metabolite of alcohol), and alleviates alcoholic liver injury.
3. Anti-inflammatory Effect: It inhibits the release of inflammatory factors (such as TNF-α and IL-6) and regulates the inflammatory response, which has a relieving effect on various inflammatory diseases.
4. Hypoglycemic and Hypolipidemic Effects: It can regulate blood sugar levels by improving insulin sensitivity and inhibiting the activity of α-glucosidase. At the same time, it can reduce the content of total cholesterol, triglycerides, and low-density lipoprotein cholesterol in the blood, and has a regulatory effect on lipid metabolism.
5. Antibacterial and Antiviral Effects: It has inhibitory effects on some common pathogenic bacteria (such as Staphylococcus aureus and Escherichia coli) and viruses (such as hepatitis B virus and influenza virus).
