Caraway is generally safe for internal use. However, the purified volatile oil should not be used by children under two years of age, as oil from caraway and other herbs in the Umbelliferae family can be irritating to the skin and mucous membranes.²⁴ Large amounts of the oil (several times higher than the recommended dosages) may be potentially abortifacient and neurotoxic and should be avoided, especially by pregnant women.
