Enhanced precautions for this plant: The Croton genus is known to contain compounds that may be irritating or toxic at high doses; internal use should never occur without the advice of a qualified professional. Do not use in pregnant or breastfeeding women, or in young children, as a precaution. Avoid prolonged or high-dose use without supervision, due to the lack of modern safety data. Not recommended in case of ongoing medication, in the absence of studies on potential interactions.

Compress — Leaves
