About
Renealmia alpinia is a flowering plant species native to the Americas, where it grows from southern Mexico through much of South America, though not in the Southern Cone. It can also be found on several Caribbean islands.
In Quechua it is called misk'i p'anqa (misk'i sweet; honey, p'anqa bract, "sweet bract" or "honey bract"). The name alludes to R. alpinia's value as a culinary herb, especially for flavoring fish. Among Spanish-speakers this species is known as jenjibre-de-jardin ("garden ginger"). Both jenjibre-de-jardin and ginger (Zingiber officinale) are in the family Zingiberaceae.
Safety
Zhou et al. (1997) of the Virginia Polytechnic Institute and State University identified three diterpenes produced by R. alpinia: 11-hydroxy-8(17),12(E)-labdadien-15,-16-dial 11,15-hemiacetal (1) and 16-oxo-8(17),12(E)-labdadien-15-oic acid (2), which are labdane diterpenes, and 8(17),12(E)-labdadien-15,16-dial (3). The team performed these assays on the basis of reports that R. alpinia may be antipyretic (fever-reducing).
