Application
1. Anti-inflammatory and bacteriostatic effect: Arbutin has anti-inflammatory and bacteriostatic effects. It is traditionally used to treat urinary tract infections, among which arbutin is its main medicinal ingredient.
 
2. Antitussive, expectorant, and asthma: Arbutin gavage can increase animal tracheal secretion, prolong the incubation period of ammonia-induced cough, reduce the number of coughs, and significantly increase the amount of phenol red excretion in the trachea. But so far, its anti-inflammatory, antitussive and expectorant mechanisms have not been reported.
 
3. Whitening and depigmentation: Arbutin is a skin lightening active derived from natural plants. It can penetrate into the skin quickly, while not affecting the proliferation concentration of skin cells, it can effectively inhibit the activity of tyrosinase in the skin, block the formation of melanin, and accelerate the decomposition and excretion of melanin through its combination with tyrosinase. , Thereby reducing skin pigmentation and removing pigmentation and freckles. It does not produce toxic, irritating, allergenic and other side effects on melanin cells, but also has emollient, trauma, bactericidal and synergistic anti-inflammatory effects. It is one of the safest and most effective whitening ingredients popular in foreign countries, and it is also the most competitive skin whitening and freckle active agent in the 21st century.
