Lithospermum is a genus of plants belonging to the family Boraginaceae. The genus is distributed nearly worldwide, but most are native to the Americas and the center of diversity is in the southwestern United States and Mexico. Species are known generally as gromwells or stoneseeds.
Lithospermum leaves are eaten by the caterpillars of certain Lepidoptera, such as the moth Ethmia pusiella which has been recorded on L. officinale.
The dried root of Lithospermum erythrorhizon is a Chinese herbal medicine with various antiviral and biological activities, including inhibition of human immunodeficiency virus type 1 (HIV-1). Lithospermum erythrorhizon is native to Japan, where it has been traditionally used to make a purple dye. In southwestern North America, a species of this genus was used as a contraceptive by the Shoshone Native American tribe.
