Scullcap Root Powder (Scutellaria lateriflora). In earlier times, Scullcap was given the common name of “Mad Dogweed,” as it was considered to be a remedy for rabies. Scullcap calms the nervous system without narcotic properties, quiets the person and often brings about, natural sleep. Many herbalists will tell you that Scullcap is the best nervine as it acts through the cerebro-spinal centers and sympathetic nervous system to control most nervous irritation. It is an effective herb to ease problems associated with drug and alcohol withdrawal and drug use; it has detoxification properties that tend to lessen the severity of such withdrawal symptoms as delirium tremors. It is well noted for its abilities in easing spasmodic afflictions such as St. Vitus’s Dance, epilepsy, etc., acting to quiet the nerves.
