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.

Tea Information

Research Summary

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.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
