In 1622 Mindererus published a treatise on a special compound of aloes which he had devised. Raymond Minderer was the most famous physician of his time. He lived at Augsburg, and was the appointed medical adviser to the Duke of Bavaria and the great house of the Fuggers, the Rothschilds of the period. Minderer’s book was entitled “Aloedarium,” and it described in loving detail each of the nine ingredients of what is supposed to have been the lineal ancestor of our modern compound rhubarb pill. The components were:—

Aloes 3 ounces, Marum (herb mastic), and Saffron, of each 3 scruples, Agaric, Costus, and Myrrh, of each 3 half-drachms, Ammoniacum, 3 drachms, Rhubarb, 3 two-drachms (ʒvi), and Lign Aloes, 3 half-scruples. These drugs were each separately macerated in appropriate liquids, the aloes in rose water, the myrrh in rue vinegar, and so forth. Mindererus recommended these pills not so much as a purgative, but as a general tonic, especially useful to strong, fair, well-fed persons.

Following Minderer’s book, and indeed slavishly copying it, came a treatise by Dr. William Marcquis of Antwerp, entitled “Aloe Morbifuga.” The only notable feature of this work is that its author is clear about the importance of that part of the aloes which is soluble in water as the constituent of the drug in which the purgative properties reside. He was, in fact, the originator of our aqueous extract of aloes.

Castor Oil.

The supposed identity of the Palma Christi tree, from the seeds of which castor oil is obtained, with the Hebrew “kikaion” is mentioned in the note on Jonah’s “gourd” in the section “Pharmacy in the Bible.” It is not doubtful that the plant was the same as the “kiki” of Herodotus, and the “kiki” or “kroton” of Dioscorides. Avicenna quotes a reference to the seeds from Dioscorides, from which, he says, is pressed the oil of kiki “which is the oil of Alkeroa.” Other Arab authors use the term “al-keroa” for the Greek “kiki.” A frequent Latin name for the Palma Christi was “kikinum,” or “cicinum.”

Castor Oil Plant.

The earliest allusion to the oil is found in Herodotus (“Hist. Euterpe,” sec. 94), where we read “The inhabitants of the marshy grounds in Egypt make use of an oil which they term the ‘kiki,’ expressed from the Sillicyprian plant. In Greece this plant springs spontaneously without any cultivation; but the Egyptians sow it on the banks of the river and the canals; it there produces fruit in great abundance, but of a very strong odour. When gathered they obtain from it, either by friction or pressure, an unctuous liquid which diffuses an offensive smell, but for burning it is equal in quality to the oil of olives.”

From this and other references it is clear that the Egyptians held the Palma Christi plant in high esteem, and this would hardly have been the case if it was only used for the extraction of an inferior burning oil. As is stated in another section, Ebers guesses that an aperient medicine made from the fruit of the kesebt tree may have meant the ricinus seeds. The seeds of the Palma Christi, too, have been frequently found in sarcophagi; evidence that they had acquired a high reputation of some kind.

Hippocrates apparently tried to reduce the acridity of the seeds so as to make them more useful as purgatives. Dioscorides alludes to their purgative properties, but only contemplates the external employment of the oil in medicine. Pliny, however, is more explicit. Chapter xli., of Book 23 begins with the sentence: “Oleum cicinum bibitur ad purgationes ventris cum pari calidæ mensura.” The whole passage is of interest. The following is the translation of it given in Bohn’s “Classical Library” (Dr. Bostock): “Castor oil taken with an equal quantity of warm water acts as a purgative upon the bowels. It is said, too, that as a purgative it acts particularly upon the regions of the diaphragm (precordia). It is useful for diseases of the joints, all kinds of indurations, affections of the uterus and ears, and for burns, employed with the ashes of the murex; it heals itch, scabs, and inflammations of the fundament. It improves the complexion also, and by its fertilising tendencies promotes the growth of the hair. The cicus or seed from which this oil is made no animal will touch, and from these grape-like seeds wicks are made which burn with a peculiar brilliancy. The light, however, that is produced by the oil is very dim, in consequence of its extreme thickness. The leaves are applied topically with vinegar for erysipelas. Fresh gathered they are used by themselves for diseases of the mamillæ and defluxions. A decoction of them in wine with polenta and saffron is good for inflammations of various kinds. Boiled by themselves and applied to the face for three successive days they improve the complexion.”
