We may not make pickling brine on the Sabbath, but one may make salt water and dip his bread in it, or add it to cooked food. Said R’ Yose: But is this not pickling brine whether it is a large or a small quantity? [Rather] these are the permissible [ways to make] salt water: One first adds oil to the water or to the salt.

We may not eat Greek hyssop on the Sabbath, because it is not food for healthy people; but one may eat pennyroyal, or drink knotgrass water. A person may eat any foods for healing; and he may drink any beverages, except for the water of palm trees or a potion of roots, because they are [cures] for jaundice. However, one may drink the water of palm trees to quench his thirst, and he may anoint himself with root oil [if it is] not for healing.

One whose teeth pain him may not sip vinegar through them, but he may dip [his bread] in vinegar in his usual manner, and if he is [thus] cured, he is cured. One whose loins pain him may not anoint himself with wine or vinegar. He may, however, anoint himself with oil, but not [with] rose oil. Princes may rub rose oil on their wounds, for such is their custom to anoint [themselves] on weekdays. R’ Shimon says: All Israel are princes.

These are the knots for which we are liable: the camel drivers’ knot and the sailors’ knot. And just as one is liable for tying them, so, too, is one liable for untying them. R’ Meir says: Any knot which one can untie with one hand, we are not liable for.
