The leaves and flowering tops are used in infusions of this plant which is native to the Iberian Peninsula.

It contains essential oil (camphor and borneol), sesquiterpene lactones, flavonoids and tannins (Sánchez 2000, Rubio 1995). It does not contain caffeine or theine.

Properties attributed to its traditional use which have not been scientifically proven: digestive, antidiarrheal (Alarcón 2015).

Indications from Commission E of the German Ministry of Health: none.

Since the last update we have not found any published data on its excretion in breast milk.

This plant is widely used in areas of the Iberian Peninsula (Calvo 2015, Alarcón 2015, Cavero 2011, Akerreta 2007, Pardo 2005) and northern Morocco.
There is very little published data on the therapeutic use of this plant, but it seems to be devoid of toxicity. The possible side effects are digestive and not serious.

Given its lack of toxicity at correct doses, its moderate consumption can be considered compatible with breastfeeding.

Precautions when taking plant preparations:
1. Ensure that they are from reliable source: poisoning has occurred due to confusion of one plant with another with toxic properties, poisonings from heavy metals that are extracted from the soil and food poisoning due to contamination with bacteria or fungi (Anderson 2017).
2. Do not take too much; follow recommendations from experienced phytotherapy professionals. "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 intoxication or act as endocrine disruptors (they contain phytoestrogens: Powers 2015, Zava 1998) if they are taken in exaggerated quantities or over extended time periods.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.
