On latest update no relevant published data on breastfeeding were found.
Side effects and toxicity have not been tested, therefore its use would be preferably avoided during breastfeeding or, as much, use it infrequently.
Topical use is compatible with breastfeeding whenever it not used on the nipple.
Prolonged or abusive use may produce hyponatremic dehydration (Grim 2018), gastritis, vomiting, sea-sickness or stupor and hepatotoxicity (Klnçalp 2012). May be confused with Equisetum palustre, which is toxic due to that it contains toxic alkaloids and thiaminase, and be cause of severe Vitamin B1 deficiency (Fitoterapia.net, Nowak 2022, Müller 2020). A case possibly related to the appearance of Autism after the prolonged use in pregnancy has been described. (Ortega 2011)
