Which species is often cited as the more medicinally significant, sometimes called "opium lettuce"?
Answer
*Lactuca virosa*
While both wild lettuce (*Lactuca virosa*) and prickly lettuce (*Lactuca serriola*) have historical medicinal uses, *Lactuca virosa* is generally the species cited when discussions focus on the most potent medicinal qualities. This specific species is sometimes colloquially referred to as "opium lettuce." This nickname stems from the milky latex that this particular plant exudes when its structures are cut or damaged, which is the primary source of the sought-after active compounds.
