Medical Properties and Uses. Every part of the Croton Tig-lium tree possesses medical properties. Among the Eastern nationsit is most highly valued for its purgative, diaphoretic, and diureticproperties: the roots, as well as the seeds, are powerfully cathartic,and very much used in some parts of Europe as a specific fordropsy; the wood of the trunk and branches, in small doses, actsupon the skin and kidneys; and the leaves, in powder, are used bythe Japanese, as a topical remedy for the bites of serpents. In thiscountry, the expressed oil is the only part medicinally employed,and when genuine, one drop proves a powerful cathartic. i. NAT. ORDER. PersonatcB. VERONICA BECCABUNGA. BROOKLIME. CUiss II.

Brooldlme is a native of the United States, although found insome parts of Eiu-ope. It grovrs by the side of brooks, and in moistlands, and sometimes in the water. This plant, although very com-mon in America, has, I think, never been accurately described by anyAmerican botanist whatever; yet some of the works speak of it, butnot as being officinal. The root is perennial, creeping, jointed, and sends forth from eachjoint numerous long slender fibres; the leaves are thick, oval, smooth,o
