In the arid lands of North America and Mexico, Croton cortesianus long featured in local herbalism, particularly for respiratory ailments. Traditional healers of desert and semi-desert areas used its leaves and bark as decoctions and fumigations, passing this knowledge down from generation to generation. This plant remains little studied by modern science today, which calls for particular caution in its use.
The leaves were traditionally prepared as decoctions to help with coughing episodes and congested airways.
Certain communities inhaled the smoke of the dried plant, a practice reported in the folk uses of northern Mexico.
The crushed bark and leaves were sometimes applied locally as a poultice to irritated skin, according to regional folk uses.
A light decoction was occasionally used by local traditional practitioners to relieve passing digestive trouble.
The genus Croton includes many species containing irritating or toxic compounds; internal use should remain exceptional and supervised by a qualified professional. Absolutely avoid in pregnant or breastfeeding women, as well as young children, because of the lack of safety data. Do not exceed small amounts and short durations of use, as prolonged use is not documented as safe. If in doubt, undergoing medication, or in a fragile state of health, consult a health professional before any use.
