Historically known as "lettuce opium," lactucarium is a milky latex produced by several species of plants in the genus *Lactuca*. While all plants in the lettuce family produce this substance to some degree, wild varieties are significantly more potent sources of lactucarium than the cultivated salad greens found in supermarkets. The concentration of this sap increases as the plant matures and begins to flower.

While the cultivated *Lactuca sativa* is a staple in most salads, with global production reaching 28 million tonnes in 2023, the edibility of wild *Lactuca* leaves is far more complex. The safety and taste of *Lactuca* leaves vary significantly between domesticated and wild species, making correct identification essential before consumption.

The Lactuca genus, encompassing common garden lettuce and wild variants, has been used in folk medicine for centuries, with ancient Egyptian hieroglyphics depicting the plant for its therapeutic qualities. The benefit of the Lactuca plant is tied to a rich concentration of bioactive compounds, though specific effects vary considerably by species.

Prickly lettuce (*Lactuca serriola*) is the wild ancestor of modern cultivated lettuces, though it is considerably more bitter and tougher. Knowing how to consume prickly lettuce safely and at the right stage of growth allows you to tap into its surprising nutritional and medicinal properties.

Historically known as 'opium lettuce' for its calming effects, wild lettuce (*Lactuca virosa*) has long been valued in traditional medicine for its unique properties. The medicinal properties of bitter lettuce are primarily concentrated in its milky sap, which contains compounds known for their mild analgesic and sedative qualities.

Historically used as a sedative and analgesic, prickly lettuce contains the milky sap lactucarium, which can cause significant side effects if ingested in large quantities. Due to the lack of regulation and research, the potential health risks associated with prickly lettuce are a serious concern for consumers.

Wild lettuce has been used in traditional folk medicine for centuries for its calming properties. To properly prepare a relaxing and effective cup, the key question is how long to steep wild lettuce to extract its beneficial compounds without creating an overpowering bitterness.

Case reports from 2009 documented several instances of toxicity from consuming wild lettuce, highlighting the importance of caution and proper preparation. Many wild lettuce species exist, and while some are edible, it's crucial to understand the risks before deciding if you can eat wild lettuce in a salad.

While some foragers consume young wild lettuce, the edibility of the plant is complex and carries significant risks, particularly with certain species and mature plants. A 2009 study even detailed eight instances of poisoning after participants consumed large amounts of raw wild lettuce.

Historically, lactucarium has been used as a folk remedy for its sedative properties, earning the nickname 'lettuce opium'. This milky sap is most concentrated in certain wild lettuce species, though many members of the daisy family contain some level of the active compounds.
