A passage from Medicinal Plants of the American Southwest:

Brittlebush tends to be diaphoretic and traditionally has been used in treating arthritic conditions aggravated by cold and damp weather. External preparations of the leaves or resin tend to be pain relieving as well. They can be used in accordance with the internal tea or tincture.
