corruption of the fruit. The principal use they made of them was in dyeing, and for this purpose they were employed until the superior coccus cacti from Mexico superseded the coccus ilicis. In the middle ages kermes was retained as the medicinal name, but for dyeing the insects were called vermiculi, and the cloth dyed by them was known as vermiculata. From this came the French word vermeil, and from that vermilion was derived.
Medicinally the coccus was principally employed by the Greek and Latin physicians as an application to wounds and for inflamed eyes. It acquired a very high reputation among the Arab doctors as a cordial for internal administration, and the famous Confection of Alkermes, invented by Mesué the younger, who was contemporary with Avicenna, continued in popular favour up to the eighteenth century. Meanwhile, the external application of kermes lingered in the use of scarlet cloth in measles, erysipelas, and other red diseases.
The original Confection of Alkermes contained juice of rennet apples, rose water, silk, kermes, sugar, ambergris, amber, yellow santal, lapis lazuli, pearls, musk, and leaf gold. In the sixteenth and seventeenth centuries this compound was prepared publicly at Montpellier, and was supplied from that city to all Europe. It was described as good for all maladies proceeding from the melancholic humour, faintings, palpitations, heart weakness, and in slow convalescence. It fortified the stomach, rejoiced the heart, and engendered good spirits. The dose was 1 drachm, or it might be applied externally on a piece of scarlet cloth.
