Nat. ord., Polygonaceae.
Synonym. - Polygonum Fagopyrum.
Habitat. - Asia, but now common in Europe and North America.
A rather extensive proving will be found in Hale's New Remedies.
Preparation. - It will be well to import the tincture, as there is a doubt as to what part of the plant was used in the proving, as in the first volume the directions are "Tincture from the whole plant, and seed at maturity;" whereas in vol. ii. it is stated, "This medicine is prepared from the stem and seed-shells of the common Buckwheat."
