Preparation and Dosage

Infusion (Tea from Leaves or Flowers):

  • Steep for 10-15 minutes and drink up to 2-3 times daily.

Tincture:

  • 2-5 ml taken up to twice daily.

Smoking (Traditional Use for Asthma):

  • Leaves were historically dried and smoked to relieve asthmatic spasms, though this practice is less common today.

Precautions and Contraindications

  • Pyrrolizidine Alkaloids (PAs): Contains low levels of hepatotoxic PAs, which can be harmful to the liver in large or prolonged doses. Use sparingly and avoid long-term use.
  • Pregnancy & Breastfeeding: Not recommended due to its PA content.
  • Liver Conditions: Avoid in individuals with liver disease or compromised liver function.
  • Children: Should be used with caution, and prolonged use is not advised.

Energetics (Traditional Medicine Perspectives)

Traditional Western Herbalism: Cooling and moistening; supports lung function and soothes irritation.
Traditional Chinese Medicine (TCM): Used for expelling phlegm and moistening the lungs; classified as a lung and spleen tonic.
European Folk Medicine: Applied for wound healing, persistent coughs, and digestive issues.

Combinations

  • For Persistent Coughs: Combine with licorice root and marshmallow root.
  • For Bronchitis & Mucus Clearing: Blend with mullein and elecampane.
  • For Sore Throats: Use with slippery elm and honey.

Harvesting and Storage

  • Harvesting:
    • Flowers are gathered in early spring before seed formation.

  • Drying:
    • Air dry leaves and flowers in a shaded, well-ventilated area.
  • Storage:
    • Keep dried material in an airtight container away from moisture and light.

Modern Research

  • Studies confirm Tussilago farfara has anti-inflammatory, expectorant, and demulcent properties.
  • Research suggests caution with long-term use due to pyrrolizidine alkaloids (PAs), which have potential hepatotoxic effects.
  • Coltsfoot remains a widely used herbal remedy for respiratory support, particularly in short-term use for acute colds and coughs.

Conclusion

Tussilago farfara is a powerful traditional respiratory remedy, valued for soothing coughs, clearing mucus, and reducing throat irritation. While effective, its pyrrolizidine alkaloid content requires mindful use, making it best suited for short-term application. Ethical and responsible usage ensures safety while preserving its medicinal benefits.
