What is dihydromyricetin powder?
Dihydromyricetin powder is Plants of the genus Ampelopsis (such as Ampelopsis oleracea and Ampelopsis jujuba), with Ampelopsis oleracea (Ampelopsis serrulata) containing the highest concentration (37.4%-38.5%).
In traditional medicine of ethnic groups such as the Tujia people, it is known as "divine tea" and "longevity tea." Modern research confirms that its flavonoids (such as dihydromyricetin) are the active ingredients.

What is dihydromyricetin powder used for?
Antioxidant: Scavenges free radicals and delays aging, with effects superior to those of vitamins C and E.
Reduces UV-induced oxidative damage to the skin and improves skin condition
Anti-inflammatory and Immune Modulatory:Inhibits inflammatory factors (such as TNF-α and IL-6), alleviating chronic inflammation such as arthritis and enteritis.Enhances immune cell activity and enhances resistance to infection.
Hangover and Liver Protection: Accelerates the breakdown of acetaldehyde, a metabolite of ethanol, reducing direct alcohol damage to liver cells.
Repairs Liver Damage: Dihydromyricetin powder can improves elevated serum enzymes (such as lactate dehydrogenase) caused by liver cell damage, inhibits collagen fiber formation, and prevents liver fibrosis.
Antiviral: Studies have shown that it can inhibit hepatitis B virus (HBV) replication and enhance immune clearance by activating the NF-κB and MAPK signaling pathways and autophagy.
Metabolism Regulators: Lowers blood lipids and blood sugar: Improves insulin sensitivity and assists in controlling type 2 diabetes and cardiovascular disease.
Anti-atherosclerosis: Lowers cholesterol and triglyceride levels.
Anti-tumor: Inhibits tumor activity in liver cancer, breast cancer, ovarian cancer, and other cancers.
Neuroprotective: Potential therapeutic effects for Alzheimer's disease, Parkinson's disease, and alcohol addiction.
Antibacterial and antiviral: Inhibits pathogens such as Staphylococcus aureus and influenza virus.

Who should not take dihydromyricetin?
Contraindications:
Pregnant and breastfeeding women: Safety is unknown; avoid use.
Severe hepatic and renal impairment: May increase liver burden, so caution is advised.
Those taking anticoagulants (e.g., warfarin): May increase bleeding risk. Individuals with allergies: May cause allergic reactions such as rashes and itching.
Precautions:
Risks of long-term use: May increase liver burden. Follow your doctor's advice and avoid blind medication.
Dietary considerations: Eat a light diet during treatment, avoid spicy and irritating foods, and get enough rest.
