Side Effects

Horsetail is generally considered safe. The only concern would be that the correct species of horsetail is used. Equisetum palustre is another species of horsetail, which contains toxic alkaloids and is a well-known livestock poison. Due to a lack of clear safety information, horsetail should be avoided during pregnancy and breast-feeding.
