"[Plin. Nat. 20.17.] - THE SKIRRET: ELEVEN REMEDIES.
The wild skirret, too, is very similar to the cultivated kind, and is productive of similar effects. It sharpens the stomach, and, taken with vinegar flavoured with silphium, or with pepper and hydromel, or else with garum, it promotes the appetite. According to Opion, it is a diuretic, and acts as an aphrodisiac. Diocles is also of the same opinion; in addition to which, he says that it possesses cordial virtues for convalescents, and is extremely beneficial after frequent vomitings.
Heraclides has prescribed it against the effects of mercury, and for occasional impotence, as also generally for patients when convalescent. Hicesius says that skirrets would appear to be prejudicial to the stomach, because no one is able to eat three of them following; still, however, he looks upon them as beneficial to patients who are just resuming the use of wine. The juice of the cultivated skirret, taken in goats’-milk, arrests looseness of the stomach.”
