Meaning
In the figurative account of the evil case of Judah and Israel because of their backsliding (Jer 30:13), the prophet says they have had no rephu'ah, or "healing medicines." Later on (Jer 46:11), when pronouncing the futility of the contest of Neco against Nebuchadrezzar, Jeremiah compares Egypt to an incurably sick woman going up to Gilead to take balm as a medicine, without any benefit. In Ezekiel's vision of the trees of life, the leaves are said (the King James Version) to be for medicine, the Revised Version (British and American) reads "healing," thereby assimilating the language to that in Re 22:2, "leaves of the tree .... for the healing of the nations" (compare Eze 47:12).
Very few specific remedies are mentioned in the Bible. "Balm of Gilead" is said to be an anodyne (Jer 8:22; compare Jer 51:8). The love-fruits, "mandrakes" (Ge 30:14) and "caperberry" (Ec 12:5 margin), myrrh, anise, rue, cummin, the "oil and wine" of the Good Samaritan, soap and sodic carbonate ("natron," called by mistake "nitre") as cleansers, and Hezekiah's "fig poultice" nearly exhaust the catalogue. In the Apocrypha we have the heart, liver and gall of Tobit's fish (Tobit 6:7). In the Egyptian pharmacopoeia are the names of many plants which cannot be identified, but most of the remedies used by them were dietetic, such as honey, milk, meal, oil, vinegar, wine. The Babylonian medicines, as far as they can be identified, are similar. In the Mishna we have references to wormwood, poppy, hemlock, aconite and other drugs. The apothecary mentioned in the King James Version (Ex 30:25, etc.) was a maker of perfumes, not of medicines. Among the fellahin many common plants are used as folk-remedies, but they put most confidence in amulets or charms, which are worn by most Palestinian peasants to ward off or to heal diseases.
