lignum nephriticumn.

Brit.

/ˈlɪɡnəm nᵻˈfrɪtɪkəm/, U.S.

/ˈˌlɪɡnəm nəˈfrɪdɪk(ə)m/

Origin: A borrowing from Latin. Etymon: Latin lignum nephriticum.

Etymology: < post-classical Latin lignum nephriticum (1592 or earlier) < classical Latin lignum wood (see lignum n.¹) + post-classical Latin nephriticum (see nephritic adj.¹).

Medicine and Science. Now historical.

A tropical wood used, in the form of an aqueous infusion, to treat diseases or pain of the kidneys (esp. kidney stones). Cf. nephritic wood n. at nephritic n. and adj.¹ Compounds.Aqueous infusions of lignum nephriticum were also well known for their changeable colour, which was later explained as fluorescence. Lignum nephriticum was originally the product of a tropical American tree (probably Eysenhardtia polystachya (family Leguminosae ( Papilionoideae))), but it may later have been obtained from an Old World species (perhaps Pterocarpus indicus of East and South-East Asia).
