Please read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before using.

Enhanced precautions for this plant: Traditional uses of this plant are poorly documented scientifically; caution is strongly advised before any use. Do not ingest without the advice of a qualified professional, as the chemical composition of the resin is not well characterized. Avoid all use in pregnant or breastfeeding women and in young children, as a precaution. In case of topical application, test on a small area first to rule out any risk of allergic reaction.

Poultice — Resin and fresh leaves

Traditional skin poultice

The exuded resin was collected or a few fresh leaves were crushed and applied directly to the affected area. This practice remains empirical and poorly formalized; it is recommended to consult a healthcare professional before any use. Dosage must be validated with a healthcare professional or a recognized pharmacopoeia before use.

Fumigation — Dried foliage

Fumigation of dried leaves

The dried foliage was burned and the smoke inhaled at a reasonable distance, according to a practice generally reported for several resinous desert shrubs. No precise protocol has been documented, so caution is essential. Dosage must be validated with a healthcare professional or a recognized pharmacopoeia before use.
