| Food & Drinks | ⭐Hangover and Liver Health 1. DHM can improve the increase of serum lactate dehydrogenase activity caused by liver cell injury, accelerate alcohol decomposition, protect the liver, accelerate the rapid decomposition of ethanol metabolite acetaldehyde, become non-toxic substances, and reduce the damage to liver cells. DHM has a rapid effect and a lasting effect. It is a good product for liver protection and hangover. 2. Dihydromyricetin (DHM) -- has the special ability to prevent drunkenness. Its magic is that it prevents the brain from feeling the intoxicating effects, no matter how high the blood alcohol level is. DHM can indeed increase the rate at which a person becomes sober after drinking alcohol. It happens in two ways: ① Reduce the impact of alcohol on the brain Most of the common symptoms of alcoholism, such as reduced inhibitions, slurred speech and loss of balance, are caused by the action of GABA receptors in the brain. Dihydromyricetin has the ability to counteract this effect, even if the blood alcohol level is still high. ② Improve liver function It takes enough time for the liver to fully process the alcohol and flush it out of the system. With the help of DHM, the liver can work faster and the patient can wake up faster. |
| Bio-pharmaceuticals | ⭐Antibacterial DHM has antibacterial effect on Bacillus subtilis, Staphylococcus aureus, Salmonella, Escherichia coli, Aerobacteria, Saccharomyces cereviscera, Rhodococcus mucosa, Penicillium, Aspergillus Niger, Aspergillus flavus, Mucor and Rhizopus, especially on Gram-positive and Gram-negative cocci or bacillus. ⭐Hypoglycemic and Hypolipidemic Pharmacological experiments in mice showed that DHM could significantly inhibit the increase of blood glucose induced by alloxan, epinephrine and streptozotocin, increase the level of serum insulin, reduce the infiltration of lymphocytes and inflammation in pancreatic tissue, and increase the number of islets. ⭐Antioxidant Purity 98% DHM can significantly inhibit the generation of malondialdehyde (MDA) in the myocardial, liver and brain homogenates of rats, and with the increase of the concentration of dihydromyricetin, the inhibition of MDA generation increases. The free radical scavenging rate of diphenyltrinitrophenylhydride (DPPH) in the experimental system is increased by the content of DHM. DHM can significantly inhibit the formation of MDA in oil, and the antioxidant activity is enhanced with the increase of the purity of DHM (60%~90%). It has a strong antioxidant effect on animal oil and vegetable oil. |
