Asteraceae · flower, leaf
Coltsfoot
Tussilago farfara
Classical European cough plant. The monograph exists because people still meet it in old books. Do not reconstruct the tea.
Safety first
Unsaturated PAs (senkirkine, senecionine). Internal cough-tea use is a hepatotoxic tradition that this catalog records as a warning, not a mapping to treat. Toxicity warning entry.
This entry exists so you do not use the plant casually. It is not a treatment suggestion.
Tradition vs trials
Traditional record. Commission E once recorded coltsfoot for cough; PA data later made internal use unacceptable in modern assessment.
Trial literature. No high-quality human efficacy file that outruns the toxicology.
Practical ranges
Educational ranges — not a prescription. Culinary use is not an extract.
