Boldo is a close relative of other fragrant leaves such as Cinnamon and Laurel. In 1875 Boldo was introduced to American and British medicinal markets. Evidence of Boldo and other medicinal herb use goes back 12500 years to Monte Verde in Southern Chile. Fossilised have eaten Boldo leaves have been found that are believed to date back around 13000 years. Today Boldo is most often enjoyed as a caffeine free hot tea.
