WATER-CALTROPS.
Project Gutenberg EPUB3 edition
Culpeper, Nicholas
They are called also Tribulus Aquaticus, Tribulus Lacusoris, Tribulus Marinus, Caltrops, Saligos, Water Nuts, and Water Chesnuts.
Descript.] As for the greater sort of Water Caltrop it is not found here, or very rarely. Two other sorts there are which I shall here describe. The first has a long creeping and jointed root, sending forth tufts at each joint, from which joints rise long, flat, slender, knotted stalks, even to the top of the water, divided towards the top into many branches, each carrying two leaves on both sides, being about two inches long, and half an inch broad, thin and almost transparent; they look as though they were torn; the flowers are long, thick, and whitish, set together almost like a bunch of grapes, which being gone, there succeed, for the most part, sharp pointed grains all together, containing a small white kernel in them.
The second differs not much from this, save that it delights in more clean water; its stalks are not flat, but round; its leaves are not so long, but more pointed. As for the place we need not determine, for their name shews they grow in water.
Government and virtues.] They are under the dominion of the Moon, and being made into a poultice, are excellently good for hot inflammations, swellings, cankers, sore mouths and throats, being washed with the decoction; it cleanses and strengthens the neck and throat, and helps those swellings which, when people have, they say the almonds of the ears are fallen down. It is excellently good for the rankness of the gums, a safe and present remedy for the king’s evil. They are excellent for the stone and gravel, especially the nuts, being dried. They also resist poison, and bitings of venomous beasts.
