Christopher Hobbs:
“Wild lettuce is a mild sedative and nervine and has been used in children’s cough medicines and in various remedies for nervous irritability. Because of its safety of use and calming effects, it is a good children’s remedy. Wild lettuce is most often combined with other sedative herbs.
It loses its potency rapidly, so most commercial preparations are very mild. One way wild lettuce can be really effective is as a dried fresh-plant juice. It is a common garden and field weed throughout the northern hemisphere. Take the fresh green tops, juice them, pour the juice into a dehydrator tray for making fruit leather, dry the juice under low heat (under 100 deg.), then break the resulting herb “wafer” up into small flakes. Take 2-3 pinches of the wild lettuce dried juice flakes as needed. The flakes can also be stuffed into capsules if the bitter, salty taste is objectionable.
Wild Lettuce has a taste of BITTER, SALTY and a temperature of COOL.”
Historical Uses
- Wild lettuce has been used for centuries as a natural pain reliever and sedative.
- In traditional medicine, it was referred to as “opium lettuce” for its latex-like sap (lactucarium), which has mild sedative and analgesic effects.
- Historically, it was used for conditions such as coughs, insomnia, rheumatism, and urinary tract issues.
Modern Clinical Uses by Herbalists and Naturopaths
- Herbalists and naturopaths today use wild lettuce primarily as a mild sedative, muscle relaxant, and analgesic for conditions like mild pain, anxiety, and sleep disturbances.
- It’s also employed as a natural remedy for migraines, menstrual cramps, and asthma.
- Modern applications often involve tinctures, teas, or encapsulated dried leaves.
Chemistry
- The active constituents include lactucin, lactucopicrin, and sesquiterpene lactones, which contribute to its sedative and analgesic effects.
- Other compounds include flavonoids, alkaloids, and coumarins.
Pharmacology
- Lactucin and lactucopicrin act on the central nervous system to exert mild sedative and pain-relieving properties.
- These compounds have shown activity on opioid receptors in lab studies, suggesting they may mimic some effects of opioids, though far less potent.
Clinical Trials
- Limited clinical trials have been conducted.
- Preliminary studies suggest mild analgesic and sedative effects, but more robust human studies are needed.
- Animal studies have supported its sedative and pain-relieving properties.
Summary
Wild lettuce has a long history of traditional use for pain relief and sedation. While modern herbalists use it for similar purposes, the lack of extensive clinical trials limits its mainstream application. Its mild pharmacological effects make it a gentle option, but safety concerns, particularly regarding high doses or contamination, require caution.
