Classical period
Around the 3rd century BC, the ancient Greek botanist Theophrastus recorded the Nile Valley oil bean in his work "Flora," clarifying its diuretic and laxative medicinal value.
In the 1st century AD during the Roman period, the Greek pharmacologist Dioscorides described in detail in "On Materia Medica" how to use sand bean to treat mouth ulcers, reduce edema, and promote menstrual flow.
