Lafoensia pacari (Lythraceae), popularly known in Brazil as "pacari", is a small tree native to the Cerrado that is used in folk medicine to treat cancer and as an anti-inflammatory and cicatrizing agent. We evaluated the genotoxic, cytotoxic, antigenotoxic, and anticytotoxic activities of an ethanol extract of L. pacari stem bark (EESB) using the Ames test and the mouse bone marrow micronucleus test.

Infusions of its leaves and twigs are used in folk medicine to treat rheumatism and renal colic, whereas the seed powder is mixed with water to treat pediculosis.
