Main Combinations:

Major Formulas:

Decoction of Hyssop and Coltsfoot (Wirtzung)
Decoction to Strengthen the Lungs
Decoction of Horehound
Pectoral Decoction (London, 1650)
Syrup of Coltsfoot Compound
Syrup for Asthma (Wirtzung)
Anti-Asthmatic Syrup (D’Aquin)
Syrup of Horehound (Fernelius)

Cautions:

1. Not used during Pregnancy or Breastfeeding; use carefully in children
2. Avoid overdose; Should not be used long-term
3. Avoid in those with Liver disease

Toxicity:

The alkaloids in Coltsfoot have been shown to be hepatotoxic, and at least one compound is carcinogenic. Animals fed large amounts (32% of their diet for 4 days, followed by 16% for the remainder of the 600 day long trial) of Coltsfoot developed Liver Cancer, whereas 1 out of 10 receiving 8% Coltsfoot in their diet developed tumors, while none receiving 4% Coltsfoot developed tumors.
However more recent studies showed Coltsfoot does not cause damage to human chromosomes, and is therefore probably not carcinogenic to humans, at least in therapeutic doses. The toxic alkaloids are said to be destroyed by boiling. Older herbalists regularly gave Coltsfoot alone or in combination for months in chronic Lung complaints with no noted ill effects.
