Mate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Tree, bush. The dried leaves in infusion (social consumption of mate) are used. Widely consumed in Uruguay, Argentina, Paraguay, southern Brazil, Bolivia and Chile. It contains alkaloids, xanthines (caffeine 2%, 0.2% theobromine, theophylline 0.05%), tannins, flavonoids. Attributed properties are: mood stimulant, diuretic, bronchodilator, vasoconstrictor. Indication by the Commission E of the German Ministry of Health (Blumenthal 1998): physical and mental fatigue.

It should not exceed the amount equivalent to 300 mg of caffeine a day (200 cc = 50-100 mg) during lactation. Average ingestion of Yerba mate by consumers is around 100-200 mg of caffeine a day, though it can reach 1 gram daily. It was published neonatal abstinence syndrome following chronic maternal consumption of mate.

At last update, there were not found published data on excretion in breast milk but it is known that xanthines are excreted in breast milk; however and since there is no proof of their effectiveness as galactagogue, it seems prudent not to increase but instead moderate the intake during lactation (Pepino 2004). A best galactagogue is a frequent and on-demand breastfeeding together with a proper technique. (ABM 2018 y 2011, Mannion 2012)

Precautions when taking herbal teas or plant preparations (Anderson 2017, Powers 2015, Posadzki 2013, Efferth 2011, Kopec 1999, Hsu 1995):

Make sure they are from a reliable source. Poisonings have occurred due to confusion of one plant with another with toxic properties (Hsu 1995), poisonings due to containing heavy metals extracted from the soil and food poisoning due to contamination with bacteria or fungi.

Do not take in excess. Follow the recommendations of professional experts in herbal medicine. “Natural” products are not good in any quantity: plants contain active substances from which a large part of our traditional pharmacopoeia has been obtained and can cause poisoning or act as endocrine disruptors because they contain phytoestrogens (Powers 2015) if they are consumed in an exaggerated quantity or time. An excessive consumption of mate (more than one liter a day) increases the risk of oro-pharyngeal-laryngeal-esophageal cancer. (Mello 2018)
