1. Isetyenziswe kwiyeza njenge-diuretic, inkqubo ye-urinary echasene ne-infective, iphinda isetyenziswe njengombala wokufota ukuphuhlisa i-stabilizer, esetyenziselwa izimonyo zokwenza mhlophe, i-freckle, ukunakekelwa kweenwele, njl.
2. I-glycosylated hydroquinone esetyenziselwa ukufunda i-melatonin biosynthesis kunye ne-inhibitor yokuchonga, ukwahlula kunye nokuchonga i-tyrosinase. I-Arbutin yi-glycosylated hydroquinone ekhutshwe kwisityalo se-bearberry. I-Arbutin yi-tyrosinase inhibitor eyaziwayo, ethi ithintele ukwakheka kwe-melanin. IArbutin ihlala isetyenziswa njengearhente emhlophe kwizinto zokuthambisa.
3. Ukuthintela umsebenzi we-melanocyte tyrosinase kwaye unqande ukuveliswa kwe-melanin ngokuvimbela i-melanin synthase.
