Low Risk

Moderately safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

A naturally grew fruit out of the Tibetan plant, which is used in the traditional Chinese Medicine. Constituents are polysaccharides, beta-sytosterol, rutin ,estrogenic flavonoids and vitamins B and C (, Gao 2017, Giner 2010).

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

It has a number of properties that are not well proven for health (Kwok 2019, Giner 1010). It can interfere with anticoagulant medications (Rivera 2012) and cause allergic reactions (Larramendi 2012, Monzón 2011).

The Organization of Consumers and Users of Spain detected in 2013 contamination with heavy metals (cadmium, lead, copper) and pesticides (OCU 2013).

Plant widely used since ancient times in China (Gao 2017). Given its lack of toxicity at correct doses, moderate consumption would be compatible with breastfeeding.

Precautions when taking plant preparations:
1. Make sure they are from a reliable source: poisonings have occurred due to confusion of one plant with another with toxic properties, poisonings due to containing heavy metals extracted from the soil and food poisoning due to contamination with bacteria or fungi (Anderson 2017).
2. 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.
