Abstract

Background: In the post-Roe era, barriers to facility-based abortions may lead to an increased incidence of self-managed abortions. While misoprostol-based medication abortions have significant literature supporting its safety profile, there is a knowledge deficit within the medical community regarding the toxicities of commonly used herbal abortifacients.

Methods: This is a narrative review, based on a MEDLINE and HOLLIS database search, of self-managed abortion methods with herbal abortifacients and their associated toxicities.

Results: Common herbal abortifacients with significant morbidity and mortality implications include pennyroyal, blue cohosh, rue, and quinine. Other commonly reported abortifacients considered to be less toxic also are discussed in brief. Special considerations for hepatic, cardiac, renal, and hematologic toxicities are important in patients with significant exposures to these herbal substances.

Conclusion: There is an anticipated increase in the utility of herbal xenobiotics for self-managed abortions with post-Roe restrictions to standard mifepristone-misoprostol protocols. Frontline providers should be aware of the associated toxicities and have special considerations when treating a poisoned patient in this population.
