Dihydromyricetin (DHM) accounts for approximately 30% of the mass fraction of vine tea and is the primary flavonol compound in vine tea. Due to its unique pharmacological properties, DHM Powder has emerged as a potential alternative to feed antibiotics.

Feeding diets supplemented with vine tea extract improves livestock and poultry performance, likely by improving small intestinal morphology and digestive and absorptive function. As a multifunctional phytochemical feed additive, vine tea extract plays a significant role in intestinal development, enhancing digestive enzyme activity, and improving growth performance in poultry.

Dihydromyricetin exhibits antimicrobial, antioxidant, anti-inflammatory, and immunomodulatory pharmacological properties, enhancing antioxidant capacity and immune function in animals while also improving intestinal function and production performance. Therefore, its widespread use in livestock production could contribute to the sustainable and healthy development of the livestock industry.

1. Hangover Relief

• Accelerates Alcohol Metabolism: It significantly increases the activity of alcohol dehydrogenase and acetaldehyde dehydrogenase in the liver, accelerating the breakdown of alcohol (ethanol) into acetaldehyde, which is then further broken down into non-toxic acetic acid for ultimate excretion.
• Reducing Acetaldehyde Toxicity: By accelerating the breakdown of acetaldehyde, it effectively reduces acetaldehyde concentrations in the blood, thereby alleviating the harmful effects of acetaldehyde on the body (such as flushing, nausea, headaches, and cell damage).
• Protecting Liver Cells: Its powerful antioxidant properties mitigate the attack of free radicals produced during alcohol metabolism on liver cells, preventing fat accumulation and liver damage.

2. Powerful Antioxidant Effects

• Free Radical Scavenging: It neutralizes free radicals in the body, reducing oxidative stress. Oxidative stress is a major factor in aging, inflammation, and various chronic diseases (such as cancer, diabetes, and cardiovascular disease).
• Protecting Cells: By reducing oxidative damage, it helps protect cells throughout the body, including the brain, heart, and skin.

3. Anti-inflammatory Effects

• Inhibits inflammatory factors: DHM Powder can inhibit the production and release of key pro-inflammatory cytokines such as TNF-α and IL-6.
• Potential Applications: This suggests that it may have an auxiliary effect in treating inflammatory-related diseases such as arthritis and atherosclerosis.

4. Neuroprotective Effects

• Protects the brain: Its potent antioxidant and anti-inflammatory properties can penetrate the blood-brain barrier, protecting neurons from damage. It has a positive preventive effect on neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

Dihydromyricetin (DHM) is often combined with other ingredients to synergistically enhance its effects, particularly for specific goals like hangover relief, liver protection, and overall health.
