Nephritic Wood, (lignum nephriticum), a wood of a very dense and compact texture, and of a fine grain, brought to us from New Spain in small blocks, in its natural state, and covered with its bark.

This wood is said to be a good diuretic; and we are told it is used among the Indians in all diseases of the kidneys and bladder, and in suppression of urine, from whatever cause. It is also recommended in fevers, and in obstructions of the visera. The way of taking it among the Indians is only an infusion in cold water. These uses are not however properly ascertained.
