 The family is of little economic importance except for ornamental purposes. Many species contain oxalic acid and are eaten as salad, and as a remedy for scurvy. The roots of some are astringent; others have a purgative root, used in certain tropics for syphilis and scrofula. The Begoniaceae is one of the most important ornamental families.

'''Begoniaceae''' is a family of [[flowering plant]]s with about 1400 species occurring in the subtropics and tropics of both the [[New World]] and [[Old World]]. All but one of the species are in the genus ''[[Begonia]]''. The only other genus in the family, ''[[Hillebrandia]]'', is [[Endemic (ecology)|endemic]] to the [[Hawaiian Islands]] and has a single species. Phylogenetic work supports ''Hillebrandia'' as the sister taxon to the rest of the family. The genus ''Symbegonia'' has recently been reduced to a section of ''Begonia'' as recent molecular phylogenies have shown it to be derived from within that genus.

Members of the genus ''[[Begonia]]'' are well-known and popular [[houseplant]]s.
