Plant properties


  • Astringent, antiseptic (very oriented towards urinary tract conditions)
  • Arbutoside (or arbutin ) is stable in the drug thanks to the tannins (hence the interest in keeping the totum) but hydrolyzed by the intestinal bacteria with the release of its aglycone, hydroquinone (a phenol ), conjugated in the liver, excreted via the kidneys and then released into the urinary tract
  • Synergy with phenolic acids and piceoside
  • Diuretic ( flavonoids and glycosides)
  • Anti-inflammatory ( iridoids and allantoin )
  • It's necessary :
    • 1°) a sufficient quantity of glucoside (non-toxic) in principle up to 4 times 3 grams of drug per 24 hours, i.e. 400 to 840 mg of hydroquinone derivatives
    • 2°) provide the urine with an alkaline reaction (for example with Vichy water or sodium bicarbonate) to decompose the esters
  • The leaves are antimicrobial in vitro and in vivo against many germs ( Candida, Staphylococcus, Escherichia, Salmonella )


Bud properties


Properties of essential oil




Indications of the whole plant (phytotherapy)


  • Urinary infections, cystitis, urethritis, nephritis, pyelitis
  • Maximum urinary concentration after 6 hours (70-75% of administered dose), lasting for 24 hours
  • Depigmenting effect of the skin in cosmetics (reduction of tyrosinase and melanin)
  • Contraindicated in pregnant women, arbutoside seems teratogenic
  • Interactions: avoid drugs that acidify the urine


Indications of the bud (gemmotherapy)


Specific indications of essential oil (aromatherapy)


Known or suspected mode of action


  • Arbutoside is hydrolyzed by intestinal bacteria with release of its aglycone, hydroquinone (a phenol), conjugated in the liver, excreted renally and then released in the urinary tract
    • sufficient amount of glucoside (non-toxic)
    • It has been said that alkalinization of urine is necessary to break down esters and improve efficiency, which does not seem essential [1]


Usual formulations


  • Use cold maceration to avoid too high a tannin content , then heat in a second step to eliminate any echinococcosis





Possible side effects and precautions for use


  • Under the recommended conditions of use, the use of bearberry leaves is a safe therapeutic option for the treatment of lower urinary tract infections [2].
  • Contraindicated in pregnant women, bearberry being oxytocic and arbutoside seeming teratogenic
  • Interactions: avoid drugs that acidify the urine (vitamin C, acid fruits)
  • At high doses: nausea, vomiting, irritability, insomnia, increased heart rate, albuminuria, hematuria [3]
    • Extremely high doses (ten times the recommended amount) may cause tinnitus, dyspnoea, seizures, delirium, vomiting
