The Marshmallows are more effectual in all the diseases before mentioned: The leaves are likewise used to loosen the belly gently, and in decoctions or clysters to ease all pains of the body, opening the strait passages, and making them slippery, whereby the stone may descend the more easily and without pain, out of the reins, kidneys, and bladder, and to ease the torturing pains thereof. But the roots are of more special use for those purposes, as well for coughs, hoarseness, shortness of breath and wheezings, being boiled in wine, or honeyed water, and drank. The roots and seeds hereof boiled in wine or water, are with good success used by them that have excoriations in the bowels, or the bloody flux, by qualifying the violence of sharp fretting humours, easing the pains, and healing the soreness. It is profitably taken by them that are troubled with ruptures, cramps, or convulsions of the sinews; and boiled in white wine, for the imposthumes by the throat, commonly called the king’s evil, and of those kernels that rise behind the ears, and inflammations or swellings in women’s breasts. The dried roots boiled in milk and drank, is especially good for the chin-cough. Hippocrates used to give the decoction of the roots, or the juice thereof, to drink, to those that are wounded, and ready to faint through loss of blood, and applied the same, mixed with honey and rosin, to the wounds. As also, the roots boiled in wine to those that have received any hurt by bruises, falls, or blows, or had any bone or member out of joint, or any swelling-pain, or ache in the muscles, sinews or arteries. The muscilage of the roots, and of Linseed and Fenugreek put together, is much used in poultices, ointments, and plaisters, to molify and digest all hard swellings, and the inflammation of them, and to ease pains in any part of the body. The seed either green or dry, mixed with vinegar, cleanses the skin of morphew, and all other discolourings being boiled therewith in the Sun.

You may remember that not long since there was a raging disease called the bloody-flux; the college of physicians not knowing what to make of it, called it the inside plague, for their wits were at _Ne plus ultra_ about it: My son was taken with the same disease, and the excoriation of his bowels was exceeding great; myself being in the country, was sent for up, the only thing I gave him, was Mallows bruised and boiled both in milk and drink, in two days (the blessing of God being upon it) it cured him. And I here, to shew my thankfulness to God, in communicating it to his creatures, leave it to posterity.
