Traditional uses

Digestive

Traditional support for the liver

White ash bark was used as a decoction in certain North American folk traditions to accompany digestive and liver function.

Pain & inflammation

Relief of joint pain

Leaves and bark were traditionally used externally or as a decoction to relieve joint and muscle discomfort.

Fever

An old fever-reducing use

Like other ash species rich in bitter principles, the bark was sometimes used as a tisane to accompany feverish states.

Skin

Traditional care for skin ailments

Certain Indigenous communities applied preparations from leaves or bark to the skin to soothe irritation and minor wounds.

Precautions

Before you use it

Avoid prolonged internal use without the advice of a health professional, as the bark contains compounds whose long-term effects are poorly documented. Not advised for pregnant or breastfeeding women as a precaution, for lack of sufficient data. Do not use in children without medical advice. People undergoing medication treatment should seek advice before any use, owing to potential interactions that are poorly studied.
