Resin fumigation

Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Decoction — Bark

Bark decoction for external use

The crushed bark is boiled in water for a few minutes, then the cooled liquid is used in compresses or rubs on painful areas. Preparation reserved for external use only. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Resin — Resin

Resin in topical application

A small piece of softened resin was applied directly to insect bites or minor wounds, according to traditional use by populations of the Sonoran Desert. Reserve for healthy, non-deeply wounded skin. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Sourcing the plant

Bursera microphylla grows wild in the arid, rocky areas of the Sonoran Desert in Mexico and southern Arizona; it is rarely cultivated outside its native range. Its resin and bark may occasionally be found through herbalist shops specializing in North American desert plants.
