Mechanism of Dihydromyricetin

1. It is a new generation of natural antibiotic with broad spectrum sterilization and bacteriostasis.

Dihydromyricetin extract from Ampelopsis grossedentata has obvious inhibitory effect on common pathogenic bacteria in oral cavity and respiratory tract, such as Staphylococcus aureus, Staphylococcus epidermidis, beta hemolytic streptococcus, Escherichia coli, Proteus vulgaris and Pseudomonas aeruginosa.

At the same time, it has good antibacterial effect on common food contaminating bacteria such as Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Salmonella, Aerobacter, Saccharomyces cerevisiae, Rhodotorula glutinis, Penicillium, Aspergillus flavus, Aspergillus niger, Mucor and Rhizopus. Its broad antibacterial spectrum is very rare in the plant kingdom, and it is known as a new generation of natural antibiotics.

The throat tissue is very tender and lubricated mainly by saliva. When the throat is dry and the tongue is dry, it is easy to cause discomfort and damage the throat.

The flavonoids in Ampelopsis grossedentata can effectively rejuvenate the physiological function of salivary glands, stimulate saliva and quench thirst, lubricate the throat, and significantly improve the dry throat caused by cough, sore throat, congestion of pharyngeal mucosa, tonsillitis, and vigorous asthenic fire.

1. Antioxidant and free radical scavenging.
