Mustard, as Hippocrates remarks, is of a hot and purgative nature. Seth says that it promotes the digestion and distribution of the food. Rhases forbids it to be eaten, except along with thick articles of food.
Pliny mentions the ocymum or basil in very unfavorable terms.
The dock, rumex L., is sometimes mentioned as a pot-herb, but does not appear to have been much in use. Horace alludes to its laxative properties. Galen says some women affected with pica and bizarre children eat the oxylapathum (rumex acutus L.) raw, but that it is still less nutritious than the lapathum.
Capers, says Aëtius and Seth, consist of different qualities, as bitterness, which renders them detergent, purgative, and penetrative; acrimony, which makes them calefacient, discutient, and attenuant; and sourness, which renders them astringent. Serapion says that, when pickled with vinegar, they strengthen the stomach and whet the appetite. When pickled with salt, he says, they are bad for the stomach. Galen recommends pickled capers in obstruction of the liver and spleen.
The buglossum, or borage, is frequently mentioned as a herb which, when eaten, imparts gladness to the soul. Ludovicus Nonnius informs us that the Belgians still fancy that it possesses this property, and look upon it as the Homeric nepenthes.
We have had occasion to mention in another place that the ancients were fully persuaded of the aphrodisiacal properties of the eruca, or rocket.
The strychnos has been generally supposed to be some species of solanum. It is mentioned as a pot-herb by Theophrastus, Dioscorides, and Galen, but was in little repute. Several other plants are mentioned as pot-herbs by the dietetical writers, such as fennel, anise, dill, hyssop, and wild thyme, but they are of little importance.
SECT. LXXV.—ON ASPARAGI OR YOUNG SHOOTS.
Blites, lettuces, orachs, mallows, and beets have the plant juicy, but the shoot dry. The turnip, mustard, radish, cress, pellitory, cabbage, and other hot things, have the plant of a dry, but the shoot of a juicy nature. The shoots of the bushy shrubs, both the marsh and garden, and that of the bryony, are stomachic and diuretic, but of little nourishment, yet when digested they are more nutritious than those of pot-herbs. Such also are the shoots of the ground-bay.
