The leaves of this bush are commonly used and have arbutoside or arbutin as active ingredients. They also contain tannins, flavonoids, ursolic acid and hydroquinone (WHO 1999).
Traditional uses without confirmation from clinical trials: urinary tract anti-inflammatory, urinary antiseptic and diuretic (Moore 2019, EMA 2018, Regrets 2014, WHO 1999, Blumenthal 1998 p225).

At the date of this last update we did not find published data on its excretion in breast milk.

Dehydration (Soliman 2018) and retinopathy (Wang 2004) due to excessive dosage and continuous use have been reported as serious side effects.

Several lactation experts discourage its use during breastfeeding (WHO 1999, Kopec 1999, Blumenthal 1998 p225).

Plant widely used in many cultures, including during pregnancy (Kennedy 2013). Given the lack of toxicity at common doses, moderate and occasional consumption would be compatible with breastfeeding.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.

José María Paricio, founder of e-lactancia.
