Enhanced precautions for this plant: Poorly documented pharmacologically and may contain irritant or toxic compounds at high doses: internal use is not recommended without supervision by a qualified professional. Contraindicated in pregnant or breastfeeding women, as well as in young children, due to lack of safety data.

In case of topical application, test on a small area first, as the plant may be irritating to sensitive skin.

Light decoction — Dried leaves

Traditional diluted decoction

A small quantity of dried leaves is briefly boiled in water, then heavily diluted before any consumption. This preparation, reported in certain desert traditions, requires consultation with a professional before any internal use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Poultice — Fresh or rehydrated dried leaves

Soothing poultice

The leaves are coarsely crushed, sometimes slightly moistened, then applied directly to the affected area using a clean cloth. This traditional external application is limited to short durations. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Fumigation — Dried branches and leaves

Traditional fumigation

Dried branches were sometimes burned at a safe distance to inhale the vapors for respiratory complaints, according to traditional uses reported in the Sonoran Desert and neighboring regions. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
