Botanical name: 

Anthora sive aconitum salutiferum.

There are many poisonous aconites, not used; but there is one medicinal and kept in the shops: this is called the wholesome aconite and antithora. (... all Aconite species are toxic. -Henriette)

It is a small plant, a foot high, with pale green divided leaves and yellow flowers. It grows erect, and the stalk is firm, angular, and hairy; the leaves do not stand in pairs. The flowers are large and hooded, and of a pleasant smell: the seed-vessels are membranaceous, and the seeds black; the root is tuberous, it sometimes consists of one lump or knob, sometimes of more. It is a native of Germany, but we have it in gardens. The root is the only part used; it is supposed to be a remedy against poisons, but it is not much regarded at this time.

The Family Herbal, 1812, was written by John Hill.
