Wild lettuce as a natural herbal medicine

Wild lettuce (Lactuca virosa) has a milky, bitter tasting sap that contains the compounds lactucin, lactucopicrin, and lactucarium. These compounds have sedative and analgesic effects which can help treat anxiety, panic attacks, insomnia, and pain.

Wild lettuce is also used to treat some lung conditions and cough. It also has anti-inflammatory properties, which makes it useful when treating arthritis and other inflammatory conditions.

Wild lettuce and pain relief

Wild lettuce is good for muscle pain, headache, and menstrual cramps. Wild lettuce has analgesic effects that fight pain and inflammation.

The pain-relieving effects of wild lettuce are thought to be due to its content of sesquiterpene lactones, a group of compounds that have sedative and analgesic properties.

Please note that wild lettuce does not get people “high” like morphine and opium. Never take large amounts of wild lettuce. Too much can be poisonous! Wild lettuce can be toxic, especially when fresh.

Wild lettuce and insomnia

Wild lettuce can help to promote sleep. It is thought to work by increasing the production of the neurotransmitter GABA, which has a calming effect on the brain.

Wild lettuce helps to treat insomnia naturally by calming the central nervous system. It can also be used to treat restless leg syndrome.

Wild lettuce and anxiety

Wild lettuce can help to reduce anxiety and panic attacks. It is thought to work by blocking the action of the neurotransmitter glutamate, which is involved in the transmission of anxiety signals in the brain.

Wild lettuce promotes relaxation that can help calm generalized anxiety disorders and panic disorders.

Wild lettuce and cough

Wild lettuce can help to suppress coughs naturally by reducing inflammation and mucus production. It can be used to treat coughs caused by colds, the flu, and allergies.

More research is needed to determine the effectiveness and safety of wild lettuce for these uses.

More about wild lettuce

Wild lettuce is also known as bitter lettuce, opium lettuce, poisonous lettuce, tall lettuce, and great lettuce. It is native to Europe, the Middle East, and North America .

It is cultivated in different regions of the world, including Austria, France, Germany, Scotland, and Iran.

Wild lettuce sap

The whole plant is rich in a milky juice that flows freely when it is scratched. When dried, it hardens, turns brown, and is insoluble in water. It is best made into tincture or extracted into alcohol.

Wild lettuce tincture is a diuretic, laxative, and sedative agent which decreases gastrointestinal inflammation and slows uterus contractions. It has anticonvulsant and hypnotic effects as well.

Before and during the Victorian period, wild lettuce was well known as a painkiller and sedative. Wild lettuce, especially the tincture, was used for kidney disorders, cramps, and edema.

In its catalogue of medicinal plants published in 1917, the Servall Company asserted that wild lettuce was “highly esteemed to quiet coughing and allay nervous irritation, a good safe remedy to produce sleep, to be used when opium and other narcotics are objectionable”.

This was written at a time when opium and cocaine could still be obtained over the counter.

Science and wild lettuce

A study published in the journal "Phytomedicine" found that wild lettuce extract was effective in reducing anxiety in rats. The study participants were given either wild lettuce extract or a placebo. The wild lettuce extract group showed a significant reduction in anxiety symptoms, such as increased heart rate and blood pressure, compared to the placebo group.

Another study, published in the journal "Journal of Ethnopharmacology", found that wild lettuce extract was effective in reducing anxiety in humans. The study participants were given either wild lettuce extract or a placebo. The wild lettuce extract group showed a significant reduction in anxiety symptoms, such as worry and nervousness, compared to the placebo group.

There is some scientific evidence to support the use of wild lettuce for pain relief. In a study published in the journal Phytomedicine, researchers found that wild lettuce extract was effective in reducing pain in rats with arthritis.

Another study, published in the journal Pain, found that wild lettuce extract was as effective as ibuprofen in reducing pain in people with chronic low back pain.

However, it is important to note that these studies were small and more research is needed to confirm its effectiveness and to determine its potential side effects.
