Gnaphalium is a genus of flowering plants in the daisy family, Asteraceae. It contains about 120 species, which are commonly called cudweeds. They are mostly found in temperate regions, although some are found on tropical mountains or in the subtropical regions of the world.

Cudweeds are important foodplants for American Painted Lady caterpillars.

Secondary metabolites[edit]

Gnaphalium species are known to contain flavonoids and diterpenes. Recently, two unique caffeoyl-D-glucaric acid derivatives, leontopodic acid and leontopodic acid B formerly only known from Leontopodium alpinum (L.) Cass. were detected in various species of Gnaphalium together with similar formerly unknown compounds.[2]
