Lopeziana Radix

A root brought from Goa, and first described by Gaubius in his Adversaria. It is brought to us in pieces, about two inches thick; of which the woody part is lightish and white, the medullary part more dense and reddish. The bark is rough, wrinkled, brown, soft, and apparently woolly, covered with a paler cuticle. Neither had any striking smell or taste; but it was found highly useful in colliquative diarrhoeas, especially in the last stages of phthisis, appearing to act rather as a narcotic than an astringent. Gaubius thinks that it resembles the sima-rouba.

Ludus Helmontii

(From its resemblance to a die). A roundish mass, which seems to have cracked in drying, and the interstices to be filled up by a calcareous matter, which frequently rises above the surface. The whole is an argillaceous clay, and the mass consists of prisms of different sizes separated by the calcareous matter. See Hauy, iv. 455.

Paracelsus described the cubic pyritae, which are like dice, and called them ludi: Helmont mistook him, and supposed this stone, which is mostly divided into squares, by the cracks to be the substance. The spar that fills up the cracks is only to be used; for it is that alone which promotes urine, and is supposed a remedy for the stone.
