* The name "bearberry" for the plant derives from the edible fruit which is a favorite food of 

bears. The leaves of the plant are used in herbal medicine.

* It's distributed in the mountains of Sichuan, southwestern China north and east to eastern 

Siberia, Alaska and northern Canada east to northern Quebec.

* The plant contains arbutin, ursolic acid, tannic acid, gallic acid, some essential oil and 

resin, hydroquinones (mainly arbutin, up to 17%), tannins (up to 15%), phenolic glycosides 

and flavonoids.

 

* Arbutin is extracted from the bearberry plant in the genus Arctostaphylos. 

* It inhibits tyrosinase and thus prevents the formation of melanin. Arbutin is therefore used as a 

skin-lightening agent. 

* There are 2 types of arbutin, they are alpha-arbutin and beta-arbutin. The Inhibition of tyrosinase activity of alpha-arbutin is 10 times stronger than beta-arbutin.
