Botanical Description

A low perennial with a single bright yellow dandelion-like composite flower on a scaly reddish stem before leaves, and large rounded hoof-shaped woolly grey-green leaves with toothed lobes; the leaves are the part used (with PA caution).

Also known as: Coughwort, Son-Before-Father, Horse Hoof

Historical Background

Coltsfoot has been a classic European respiratory herb for millennia, its bright flowers brewing before the leaves emerge (hence 'flowers before leaves'). Named for its hoof-shaped leaves, it was sipped for cough and throat traditions, now used with care for its PA content.

Earliest recorded uses: European folk traditions for millennia; a classic respiratory herb, flowers brewed before leaves emerge.

Flavor & Aroma

Aroma: Mild, slightly sweet, herbaceous, honeyed

Tea Preparation

Modern Evidence

Coltsfoot has a long European tradition for respiratory and throat comfort, but the leaves contain pyrrolizidine alkaloids (PAs) that can harm the liver, so use is restricted in many countries. It is not a treatment for cough, asthma, or any disease; prefer PA-free sources and limit use.
