Holostium, is possessed of desiccative powers with astringency. Hence they use it for fractures.
Commentary. There are few articles in the Materia Medica of the ancients about which there is so much doubt. See Parkinson (Theatre of Plants), and Sprengel in Dioscor. (iv, 11.) It has been set down as the Holosteum umbellatum, but all upon mere conjecture. Our author here copies from Galen, who in his turn borrows from Dioscorides. We are not aware of its being described by any of the Arabian authorities, nor have we found it in any modern Dispensatory.
Ὀμφάκιον,
Omphacium is the Juice of the Unripe Grape, being considerably astringent and desiccative in the third degree. Hence it applies to defluxions, and especially those of the stomach.
Commentary. The juice of unripe grapes is called Agresto in Italy, where it is still used in affections of the throat. Dioscorides recommends it in such cases. Pliny says of it, “Prodest dysentericis, sanguinem excreantibus, anginis.” (H. N. xxiii, 4.) This is a literal translation from Dioscorides, who recommends it in these cases, and also for various others in which astringents are indicated, such as aphthæ, loose gums, fistulæ, old ulcers, spreading sores, and as an application to asperity and ulceration of the eyelids. (v, 6.) Celsus prescribes the omphacium in a variety of cases, as a cleansing medicine, (v, 5), as one that corrodes (v, 6), and as one that determines outwardly. (v, 12.) None of the other Greek authorities nor the Arabians supply any additional information of interest after Dioscorides.
Ὀνάγρα,
Onagra, Tree Primrose (called also Œnothera and Œnothyris), is a sort of plant resembling a tree, the root of which, when applied as a cataplasm, proves soothing to the bites of venomous animals.
Commentary. It would appear to be either the Œnothera Onagra, Tournefort, or the Epilobium angustifolium L., Narrow-leaved Willow-herb, as Sprengel supposes. Dioscorides describes it minutely, but, like our author, merely recommends it in malignant sores. (iv, 116.) Galen strangely, as we would suppose, says of it, that its juice is of a venous nature, and of the same power as wine. As far as we have been able to discover, it is not to be found in the works of Hippocrates, Celsus, or any of the Arabians. It is worthy of remark that the Epilobium angustifolium, although it does not hold a place in our Mat. Med., is still known to the vendors of medicines, and retains the characters which it obtained from the ancients. See Gray (Suppl. to Pharmacop. 84.) This confirms the conjecture that the onagra is this plant. We would further mention, as confirmatory of this opinion, that the E. angust. has been cultivated about gardens in this country from time immemorial, so that there is every reason to believe that it had been introduced by the Romans, no doubt on account of its supposed efficacy in medicine.
