lignum nephriticum
/ˈlɪɡnəm nɪˈfrɪtɪkəm/Medicine and Science. Now historical
noun
A tropical wood used, in the form of an aqueous infusion, to treat diseases or pain of the kidneys (especially kidney stones).
- 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)..
Origin
Mid 17th century; earliest use found in John Parkinson (1566/7–1650), apothecary and herbalist. From post-classical Latin lignum nephriticum from classical Latin lignum wood + post-classical Latin nephriticum.
