“Common mallows are generally so well known that they need no description.” And “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 Plague in the Guts, for their wits were at ne plus ultra about it. My son was taken with the same disease; myself being in the country, was sent for; the only thing I gave him was Mallow bruised and boiled both in milk and drink; in two days it cured him, and I have here to shew my thankfulness to God in communicating it to his creatures, leaving it to posterity.” – Nicholas Culpepper (1616-1664)
