Likely Compatibility

Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.

The root of this herbaceous plant is used. It contains carbohydrates (inulin), mucilage, phenolic acids and phytosterols.
Traditional indications which have no conclusive clinical evidence (EMA 2010): diuretic, anorexia, acne, seborrhea. The E Commission of the German Ministry of Health discourages its use because its properties are not proven (Blumenthal 1998 p 318).
Used for culinary purposes in some Asian countries.

Since the last update we have not found published data on its excretion in breastmilk.

It is devoid of toxicity and has few published side effects.

Given its lack of toxicity at correct doses, moderate consumption would be compatible with breastfeeding.
An old published study of intoxication was due to contamination of a burdock preparation with another product (Bryson 1978, Fletcher 1978).

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 heavy metals that are extracted from the soil and food poisoning due to contamination with bacteria or fungi (Anderson 2017).
2. Do not take in excess; follow recommendations from experts in phytotherapy. “Natural” products are not good in any quantity: plants contain active substances from which much of our traditional pharmacopoeia has been obtained and can cause poisoning or act as endocrine disruptors (they contain phytoestrogens: Powers 2015, Zava 1998) if consumed in exaggerated quantities or periods of time.

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.
