Derivation of the botanical name:
Lactuca, Latin lact, milk, referring to the milky sap.
serriola, pertaining to salad, being one form of an old name for chicory.
scariola, an Italian name for Succory (Nicholas Culpeper).
The Hebrew name: חסה, hasa (New Hebrew), lettuce; from Aramaic: חסא, which is of uncertain origin.
The history of Lactuca (lettuce) can be traced way back to the ancient Egyptians. Lactuca was closely associated with Min, the Egyptian god of fertility, and also featured in the aftermath of the homosxual assault of Seth on Horus. Thus the lettuce aquired the reputation of being aphrodisiac. Min is often depicted holding a rosette of Lactuca Serriola. Lactuca was also used by the Romans and Augustus was said to have raised a statue in honor of the Lettuce infusion that he claimed saved his life.
Pliny the Elder (23 - 79 AD), wrote extensively of Lactuca in his work Naturalis Historia.
Dioscorides (circa 40—90 AD) says that "it is similar in virtue to the Poppy," since it is suporific and painkilling.
Lactucarium was produced by pharmaceutical companies until about the 1940's.
