This botanical illustration of the cannabis plant was made by Elizabeth Blackwell in 1737. According to her description, “the stalks grow about five foot high, the leaves are a deep green above and a light green underneath. It is planted in fields and gardens yearly, and produces its seed in August; for this species of hemp never bears any visible flower.” Elizabeth Blackwell also points out the medicinal benefits of the plant. “The seed being boiled in milk, till it cracks, is accounted good for old coughs, and a specific to cure the jaundice.”
