Carlinethistle root tea is listed in the German Commission E monographs as a diuretic and was used in folk medicine for treating digestive disorders, inducing sweating and as a gargle for treating catarrh (mucous) of the upper respiratory tract.
Carlinethistle root is generally taken as an herbal tea one to three times per day.
Thistle is the common name of a polyphyletic group of flowering plants characterised by leaves with sharp spines on the margins, mostly in the plant family Asteraceae.
