Adults and children older than 12 years of age may take 1/2–3/4 teaspoons (3 grams) per day.¹² To prepare tea, boiling water is poured over 1/4–1/2 teaspoon (1 to 2 grams) of finely cut sundew root and above-ground parts, then strained after steeping for ten minutes. One cup (250 ml) may be taken three to four times daily. In Europe, liquid preparations of sundew are often combined with thyme, another antitussive, in cough syrups for adults and children. A tincture of sundew, 1/8–1/4 teaspoon (0.5 to 1.0 ml) three times per day, is also sometimes used.
