Commonly found in the regions of North America, skullcap herb has been used in traditional medicine since ages. It actually refers to any species of the genus Scutellaria, belonging to the family Labiatae.
The genus includes about 300 distinct species, out of which two species, Scutellaria lateriflora and Scutellaria baicalensis, are often used in herbal medicine to treat various ailments. 
Scutellaria lateriflora, also known as American skullcap, is used as an effective therapy for stress, anxiety and nervous tension. The other species, Scutellaria baicalensis, is known as Chinese skullcap and has been a part of the traditional Chinese medicine for years.


Skullcap is a perennial herb that grows up to a height of 3 feet or more. It is characterized by small, two lobed flowers that are bluish purple to pink in color. The double lobed flowers resemble the skullcaps worn in medieval times and hence the name 'skullcap' herb.
This herb is generally taken in the form of skullcap tea or tinctures. It is also available in form of liquid extracts, capsules or as dried herb. Skullcap extraction is normally done using alcohol. Recommended dosage for adults is 2 to 3 ml of the fluid extract or 1 to 2 grams of the dried skullcap herb. It can also be given to children but in small doses.

American skullcap is used as a mild relaxant and as an effective treatment for conditions like insomnia, fibromyalgia, etc. It is used as an emmenagogue to promote menstrual discharge. It is also effective in reducing muscle spasms and convulsions.
Chinese skullcap is used in traditional Chinese medicine to treat allergies, infections, headaches and inflammations. It is known to have antifungal and antiviral effects and thus can prevent a number of infections. It helps in reducing symptoms of hypertension and diabetes.
Chinese skullcap herb is also known to have some cancer fighting properties, however, studies are still going on to confirm its action.
