The plant, particularly the bark, contains potent compounds like lapachol, which can be toxic in high doses and may cause side effects such as nausea, anemia, and potential anticoagulant effects. INTERNAL USE IS NOT RECOMMENDED without the guidance of a practitioner experienced in its ethnomedical context. Topical use should be preceded by a patch test.
