The white, five-petaled flowers are in bloom in June &/or July.

In Baja California, this plant is found growing in the foothills of the Sierra de Juarez and the Sierra de San Pedro Martir, but it can be found growing further south on the sky islands of the Sierra de la Asamblea and the Sierra de San Borja.^[1]

Uses

Eriodictyon angustifolium extract, but not Eriodictyon californicum extract, reduces human hair greying.^[2] Sterubin is the most abundant flavonoid in Eriodictyon angustifolium extract.^[2]

Dietary eriodictyon angustifolium tea supports prevention of hair graying by reducing DNA damage in CD34+ hair follicular keratinocyte stem cells.^[3]
