American skullcap is a perennial that can reach heights
of three feet or more. It is a member of the mint family and is
found in the woods and damp meadows throughout Northern America. Its
blue flowers bloom in the late summer. They are collected along with
the leaves and stems to be dried for use in
medicine.
American skullcap is not to be mistaken for its
related species called Baikal or Chinese skullcap (Scutellaria
baicalensis).
Because of its slightly calming effects,
American skullcap has been used as the main component in a variety
of medicinal tonics. Today it is more effective and less harmful
than in years past. Skullcap (Scutellaria lateriflora), or “mad dog
weed”, was used for rabies. It has been used for over two hundred
years as a mild relaxant that affects the nervous and
musculoskeletal systems. It has also been used in therapy for
anxiety, nervous tension, hysteria, and convulsions and is currently
also used in connection with symptoms associated with premenstrual
syndrome (PMS), stress-related headaches, anorexia nervosa, and
insomnia.
Today skullcap is commonly used to treat anxiety,
nervous tension, muscle spasms, PMS-related symptoms, tension
headaches, restless legs syndrome, insomnia, and mild Tourette’s
syndrome.
