Anthora Pharm. Paris. Antithora. Aco-nitum salutiferum five anthora C. B. Aconitum Anthora Linn. Yellow helmet flower: a plant with divided leaves, and naked flowers confiding of five petals, the uppermost of which is shaped like a hood: each flower is followed by three or more pods, containing wrinkled angular seeds. It is distinguished from the other aconites or wolfsbanes, by the leaves not being glossy, by their being cut quite down to the pedicle, and by the segments being very narrow and of nearly the same width from end to end.
This plant is a native of the Alps and Pyre-neans, from whence the dried roots are some-times brought to us. They are generally of an irregular roundish shape, sometimes a little oblong, of a brown colour on the outside and white within, hard to break, but not tough.
The root of anthora has a faint smell, and an acrid bitter taste, constringing the fauces and throat, accompanied with a kind of nauseous sweetishness. Its medical qualities are doubtful. Some (b) look upon it as a safe anthelmintic, an useful alexipharmac in malignant fevers, and even as an antidote to the poisonous aconites, particularly the species called thora, from its supposed efficacy against which it is said to have received its name: others (a) ascribe to it virulent qualities, and relate instances of its occasion-ing vomiting, purging, great disorders of the stomach, heat, thirst, and anxiety. A competency of experiments, to fully determine this point, is as yet wanting: possibly this root, like many others, may be possessed of noxious qualities when fresh, which are in great measure dissipated or destroyed by drying or long keeping. But as all the salutary effects, chat can be rationally expected from this drug, are obtainable from medicines of known innocence; common practice has never received the anthora, and the colleges both of London and Edinburgh have now expunged it from their catalogues of officinals.
