The Nine-leaf lomatium, Lomatium triternatum
#OTD Today, on May 6, 1806, along the banks of Idaho’s Clearwater River, Lewis and Clark discovered the Nine-leaf lomatium, Lomatium triternatum.
A species of flowering plant in the carrot family and known by the common name nineleaf biscuitroot, the nine-leaf lomatium is so-named because each leaf divides into three narrow leaflets that, in turn, divide into three more (triternatum, from the Latin, means “three times three”).
Lewis and Clark collected many varieties of lomatiums which are found only west of the Mississippi River.
Lomatiums are used by herbalists as a remedy for viral illnesses. In 2018, the NIH reported the case of a woman who had taken lomatium extract - marked LDM-100 - for the flu and ended up with a severe rash all over her body for a week.
