Skullcap is a Native American plant used widely by the Indians, then the Colonists when they arrived. It is a strong nervine, that is, a sedative for the nerves. It is used to treat everything from ADD to hysteria, and even epilepsy. It is also anti-inflammatory and anti-spasmodic which help make it a total nerve tonic. You can get too much of a good thing, though, so use it moderately. Many varieties of skullcap grow in this country and all can be used.
