Wild lettuce (Lactuca virosa), sometimes called “opium lettuce,” has a long history as a natural remedy for pain and tension relief. Despite the nickname, it contains no opiates, its strength lies in a white, milky sap called lactucarium, found in the plant’s stem and leaves. This sap has traditionally been used for its mild sedative and analgesic (pain-relieving) properties.
In this guide, you’ll learn how to identify and harvest wild lettuce sap, explore its common uses and benefits, and understand the important safety precautions to keep in mind.

Wild lettuce grows up to 6 feet tall and has tall, spiny leaves with a blue-green tint.

2. Extracting the Sap
- Choose mature plants, they produce more lactucarium.
- Cut the stem near the base using a clean, sharp knife.
- Let the sap slowly ooze out and collect it with a spoon, or scrape it onto a clean glass or ceramic surface.
- Allow the sap to dry partially before sealing it in an airtight container for storage.
- For larger amounts, repeat the process across several plants, but always harvest sustainably.
