Interesting Observations

Wild lettuce latex can be sun dried to obtain a dark mass called “lactucarium”, which has a calming effect, but ask your doctor or pharmacist about dosage and possible contraindications. The species called wild lettuce (Lactuca virosa) seems to give a higher concentration and quantity of “lactucarium”.

“Lactucarium” is sometimes described as “lettuce opium” and can be compared to poppy opium. However, this description and comparison is wrong as “lactucarium” does not contain opiates.

Lettuce is a kind of lettuce very close to wild lettuce. Read our Lettuce File
