Sweet Flag, Calamus

High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

The rhizome of the plant is used in traditional medicine as an antispasmodic and antisecretory and nematocidal in dyspepsia and as an appetite stimulant. It contains essential oil with mono and sesquiterpenes, phenylpropanoids such as ß-asarone, starch, saponins, tannins, alkaloids and resin. There is no scientific evidence of its alleged properties. Because of the possible mutagenic and carcinogenic properties of ß-asarone, its commercialization is prohibited in many countries. (Fitoterapia.net, EFSA 2012, MSC 2004)

At the time of the last update, we found no published data on its excretion in breast milk.

Given the scarce bibliographic references of this plant, its potential toxicity and its lack of proven therapeutic indications, its consumption is dispensable, especially during lactation.

 

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.
