Coltsfoot Leaf
Coltsfoot leaf has a long history as a cough and throat herb, but modern herbal safety practice flags it as HIGH RISK because it may contain pyrrolizidine alkaloids (PAs), which are associated with liver injury. If coltsfoot is used at all, it should only be from PA-free verified sources and only short-term.
Key Benefits
- Traditional soothing support for cough and throat irritation
- Historically used in cough teas and syrups (short-term)
- Best replaced with safer demulcents unless PA-free verified
- Educational example: safety and sourcing matter
Common Issues It May Help With

- Throat irritation (supportive)
- Chest irritation (supportive)
How To Use (Simple)
- Prefer safer herbs (mullein, marshmallow root, thyme, honey) first. If used, only choose PA-free verified products. Use short-term only and follow label directions.
Taste / Notes

Evidence Level
Traditional use exists, but safety concerns reduce practical recommendation. Safer alternatives are generally preferred.
Cautions
