Pour simmering water over a small quantity of dried leaves and let steep for about ten minutes before straining. This mild tea was traditionally drunk in small amounts, not exceeding one to two cups per day. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

The leaves were sometimes crushed or infused and then applied warm as a compress to the skin for traditional external use. Renew the compress once or twice daily depending on skin tolerance. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to Find It

Obtaining the Plant

Ceanothus fendleri grows wild on rocky and brushy slopes in the Southwestern United States; in France, it is rarely found except from a few herbalist shops specializing in North American plants or from nurseries passionate about hardy plants.

Harvest Season

When to Harvest

The leaves are gathered in spring and summer when the foliage is well developed, while the roots are traditionally harvested in autumn, once the sap has descended.
