This thrush is a distemper that children are very subject to, and it arises from bad milk, or from foul humour in the stomach; for sometimes, though there be not ill humour in the milk itself, yet it may corrupt the child’s stomach because of its weakness, or some other indisposition; in which, acquiring an acrimony instead of being well digested, there arise from thence biting vapours, which, forming a thick viscosity, do thereby produce this distemper.

Cure.—It is often difficult, as physicians tell us, because it is seated in hot and moist places, where the putrefaction is easily augmented; and because the remedies applied cannot lodge there, being soon washed with spittle. But if it arises from too hot quality in the nurse’s milk, care must be taken to temper and cool, prescribing her cool diet, bleeding and purging her also, if there be occasion.

Take lentiles husked, powder them, and lay a little of them upon the child’s gums. Or take bdellium flower half an ounce, and with oil of roses make a liniment. Also wash the child’s mouth with barley and plantain water, and honey of roses, or syrup of dry roses, mixing with them a little verjuice of lemons, as well to loosen and cleanse the vicious humours which cleave to the inside of the child’s mouth, as to cool those parts which are already over-heated. This may be done by means of a small fine rag fastened to the end of a little stick, and dipped therein, whereby the ulcers may be gently rubbed, being careful not to put the child in too much pain, lest an inflammation make the distemper worse. The child’s body must also be kept open, that the humours being carried to the lower parts, the vapours may not ascend, as it is usual for them to do when the body is costive, and the excrements too long retained.

If the ulcers appear malignant, let such remedies be used to do their work speedily, that the evil qualities that cause them being thereby instantly corrected, their malignity may be prevented; and in this case touch the ulcers with plantain water, sharpened with the spirits of vitriol; for the remedy must be made sharp according to the malignity of the distemper. It will be necessary to purge these ill humours out of the whole habit of the child, by giving half an ounce of succory with rhubarb.

Sect. V. Of Pains in the Ears, Inflammation, Moisture, &c.

The brain in infants is very moist, and hath many excrements which nature cannot send out at the proper passages; they get often to the ears, and there cause pains, flux of blood, with inflammation, and matter with pain; this in children is hard to be known, as they have no other way to make it known but by constant crying; you will perceive them ready to feel their ears themselves, but will not let others touch them if they can prevent it; and sometimes you may discern the parts above the ears to be very red.

These pains, if let alone, are of dangerous consequences, because they may bring forth watchings and epilepsy; for the moisture breeds worms there, and fouls the spongy bones, and by degrees causes incurable deafness.

Cure.—Allay the pain with convenient speed, but have a care of using strong remedies. Therefore only use warm milk about the ears, with the decoction of poppy tops, or oil of violets: to take away the moisture, use honey of roses, and let aquamollis be dropped into the ears; or take virgin honey, half an ounce; red wine two ounces; alum, saffron, saltpetre, each a drachm; mix them at the fire; or drop in hemp seed oil with a little wine.

Sect. VI. Of Redness, and Inflammation of the Buttocks, Groin, and the Thighs of a Young Child.

If there be no care taken to change and wash the child’s bed as soon as it is fouled with the excrements, and to keep the child very clean, the acrimony will be sure to cause redness, and beget a smarting in the buttocks, groin, and thighs of the child, which, by reason of the pain will afterwards be subject to inflammations, which follow the sooner, through the delicacy and tenderness of their skin, from which the outward skin of the body is in a short time separated and worn away.
