-**Arbutus unedo leaves**, Arbute leaves, Folia Arbuti, Erdbeerbaumblätter [CRC, Hager] \\ +---- 
-Definition. Dried leaves of Arbutus unedo. \\ + 
-Constituents. The phenolglucosides arbutin (3%) and methylarbutin. Flavonolglucosides, derived from kaempferol like juglanin (kaempferol-3-arabinoside) and avicularin (kaempferol-3-arabinofuranoside) or derived from quercetin like hyperoside (quercetin-3-galactoside). Furthermore iridoidglucosides (unedoside as main glucoside, 0.2%) and tannin. [Hager; CRC; Rimpler H, Pistor H, Z. Naturf. C, 29, (1974), 368] \\ +The dried leaves of Arbutus unedo, (Arbutus unedo leaves, Arbute leaves, Folia Arbuti, Erdbeerbaumblätter) contain the phenolglucosides arbutin (3%) and methylarbutin. Also present are flavonolglucosides, derived from kaempferol like juglanin (kaempferol-3-arabinoside) and avicularin (kaempferol-3-arabinofuranoside) or derived from quercetin like hyperoside (quercetin-3-galactoside); furthermore iridoidglucosides (unedoside as main glucoside, 0.2%) and tannin. Leave extracts are antibiotic and astringent, they are used as urinary desinfectant and for diarrhea.\\ 
-Effects. Leave extracts are antibiotic and astringent. \\ +[Hager; CRC; Rimpler H, Pistor H, Z. Naturf. C, 29, (1974), 368] 
-Uses. As urinary desinfectant and for diarrhea. [CRC, Hager] \\ +
-Dosage. As decoction, 2-4g of the dried leaves per cup (150ml) of water, thrice daily. [Hager]\\+
  
 "The leaves of Arbutus unedo L. are used as a urinary antiseptic, against diabetes, an antidiarrheal adstringent, depurative, antioxidant and as an antihypertensive. Chemical investigations of leaves and fruits indicated the presence of the essential oil, flavonoids, proanthocyanidins, iridoids glucosides, sugars non-volatile and phenolic acids and tocopherol." \\ "The leaves of Arbutus unedo L. are used as a urinary antiseptic, against diabetes, an antidiarrheal adstringent, depurative, antioxidant and as an antihypertensive.
