"[Plin. Nat. 26.21.] - GEUM: THREE REMEDIES.
Geum is a plant with thin, diminutive roots, black, and aromatic. It is curative not only of pains in the chest and sides, but is useful also for dispelling crudities, owing to its agreeable flavour. Vervain, too, is good for all affections of the viscera, and for diseases of the sides, lungs, liver, and thorax. But one invaluable remedy for diseases of the lungs, and for cases of incipient phthisis, is the root of consiligo, a plant only very recently discovered, as already mentioned. It is a most efficient remedy also for pulmonary diseases in swine and cattle, even though only passed through the ear of the animal. When used, it should be taken in water, and kept for a considerable time in the mouth, beneath the tongue. Whether the part of this plant which grows above ground is useful or not for any purpose, is at present unknown. Plantago, eaten with the food, betony taken in drink, and agaric taken in the way prescribed for cough, are useful, all of them, for diseases of the kidneys.”
