Scientific Summary
Carline thistle (Carlina vulgaris) is a perennial herb whose dried flower heads and roots are traditionally used in teas and tinctures. It is most commonly taken as an adjunct to fighting colds and flu, to support the immune system, to boost endurance, and for conditions such as chronic diarrhoea, oedema, abnormal uterine bleeding, diabetes and as a mild cardiac tonic. When using carline thistle, avoid large doses and use it cautiously during pregnancy or if you have liver or kidney problems, as excessive intake may cause gastrointestinal upset or mild toxicity.
