Historical or traditional use (may or may not be supported by scientific studies)
As is the case in modern herbal medicine, scullcap was used historically as a sedative for people with nervous tension and insomnia. It was, and continues to be, commonly combined with valerian for insomnia.1 It was also used by herbalists as a remedy for epilepsy and nerve pain.
Active constituents
Few studies have been completed on the constituents of American scullcap. One of its constituents, scutellarian, has been reportedly shown to have mild sedative and antispasmodic actions in animal studies.2 Human trials have not yet been conducted to confirm the use of scullcap for anxiety or insomnia.
How much is usually taken?
Scullcap tea can be made by pouring 1 cup (250 ml) of boiling water over 1–2 teaspoons (5–10 grams) of the dried herb and steeping for 10 to 15 minutes. This tea may be drunk three times per day.3 Alternatively, tincture made from fresh scullcap, 1/3–3/4 teaspoon (2–4 ml) three times per day, may be taken.
Are there any side effects or interactions?
Use of scullcap in the amounts listed above is generally safe. However, scullcap use during pregnancy and breast-feeding should be avoided due to limited information about its safety. Cases of liver damage have been reported in association with the intake of scullcap. However, on closer examination, it appears these scullcap products actually contained germander (Teucrium chamaedrys), an herb known to cause liver damage.4
One case report exists of a 28-year-old man who died of liver failure after taking unspecified amounts of scullcap, pau d’arco and zinc.5 It appears likely that this, too, may have been a case of adulteration of scullcap with germander.6
At the time of writing, there were no well-known drug interactions with American scullcap.
