Wormseed Essential Oil
Wormseed is a hairy, coarse, perennial wayside herb up to 1 meter high with stout, erect stem, oblong-lanceolate leaves and numerous greenish-yellow flowers, the same color as the leaves. The essential oil is obtained by steam distillation from the whole herb, especially the fruit or seeds. Wormseed is native to South America, but is cultivated mainly in east and south-east USA, also India, Hungary and Russia. Several Indian tribes in the eastern United States used the whole of the herb decocted for various female complaints, while the Chinese traditionally used wormseed to treat articular rheumatism.
