What is wild lettuce

Description of lactuca virosa

Wild lettuce (Lactuca virosa or leaf lettuce) is a species of lettuce cultivated in various regions of the world, notably in Iran, but also in Europe, Austria, France, Germany and Scotland, as well as in Asia.

This grass grows in sunny locations, such as along rivers and roads, and can reach 1.8 meters in height. Its properties may vary depending on its origin.

Wild lettuce produces pretty yellow flowers, on which the seeds can be harvested. These seeds are used for extracts for medicinal purposes.


Leaves, seeds, latex of lactuca virosa

The leaves of the leafy lettuce lactuca virosa are bright green and grow from a green stem sometimes adorned with purple.

When you scratch the lactuca leaf, this lettuce secretes a milky white substance called lactucarium. It is distinguished by the lanceolate shape of the leaf and an appearance that sometimes recalls the dandelion or the capuchin beard.

When dried, this white product resembles opium, a pain reliever extracted from unripe poppy pods.

Opium Grain, Poppy

You should know that in herbal medicine, opium seeds have been widely used to reduce pain throughout history, and this since Antiquity. It was used in particular as an analgesic for the wounded in war.

Lactucarium can produce opium-like sensations, but with fewer side effects.

  • herbal tablets or capsules.


Parts of lactuca virosa used

Several parts of lettuce are therefore used, and not only the white milk or lettuce latex, but also the stem, the leaf, the flowers, the seeds, sometimes the rosette or the thorns.

Leaf lettuce makes it possible in particular to prepare herbal tea, but also a particular form of opium, from latex.


Herbal tea, remember, is a simple form of infusion of the leaves and stems, while the decoction consists of boiling part of the leaf lettuce until a mixture is thick enough and rich in active substances.

Main properties of wild lettuce or lactuca

Virose lettuce or lactuca virosa is a form of plant used in herbal tea, or as a seed extract, or for its juice reminiscent of white latex.


It contains active substances. Its success comes from its benefits on:

  • anxiety

  • joint pain.

Raw leaf lettuce is sometimes eaten by lovers of wild plants. The characteristic appearance makes it easy to spot.

The leaves are also psychoactive thanks to their juice and are sometimes used to create a state of euphoria, although this is not necessarily the primary function of leaf lettuce.

It should be noted that in France, although it is present, wild lettuce is little known, whatever the name given to it.

Can leaf lettuce relieve pain?

Lactuca virosa and pain

Leaf lettuce extract and seeds have long been used for pain relief.

Lactucarium contains lactucin and lactucopicrin, bitter substances which act on the central nervous system to produce an analgesic and sedative effect.

These compounds are considered sesquiterpene lactones, a group of beneficial substances most concentrated in plants belonging to the Asteraceae - such as lettuce, calendula and chicory.

In fact, sesquiterpene lactones make up a large part of the latex-like lactucarium juice secreted by leaf lettuce.

While many natural health care companies and homeopathic websites promote lactuca virosa as a pain treatment, scientific evidence is lacking.

Studies on lactosa virosa and pain

Few of human studies have looked at lactuca virosa, its white latex, and pain relief, although some animal studies suggest that the compounds in the juice or seed extract work as a pain reliever.

A 2006 study by A. Wesolowska on mice demonstrated that at doses of 15 and 30 mg of plant per kg of body weight, the product is as effective as 30 mg of ibuprofen.

However, animal studies on lactuca virosa as a pain reliever are limited, and more research including humans is needed for accurate advice.

Reliability of knowledge about leaf lettuce

Although you can find information and opinions on the healing qualities of lactuca virosa on many alternative medicine websites, there is currently no scientific research to support its use to treat any of the conditions mentioned above.

Studies show that other types of sesquiterpene lactones from the Asteraceae family are effective in reducing inflammation, which may help with certain health issues.

In addition, certain sesquiterpenes offer antioxidant, antibacterial and anti-tumor properties.

We can cite chamomile, a member of the Asteraceae family, which contains chamazulene, a sesquiterpene showing strong antioxidant qualities.

Feverfew, which also belongs to the Asteraceae categories, is rich in parthenolide, which inhibited the growth of leukemia cells in a test-tube study.

However, there are few studies on the specific compounds found in lactuca virosa.

Until more research has been done on the product's health effects, it is difficult to confirm or deny.

Reduced number of studies on leaf lettuce

Additionally, in the absence of extensive studies, there is no way to know how the seed extract may interact with certain medications.

Since animal studies indicate that lactuca virosa leaf lettuce extract may have sedative properties, anyone taking sedatives should avoid supplements of this product.

In addition, ingesting leaf lettuce can cause hallucinations.

Before using leaf lettuce, you can nevertheless consult a health professional or ask the pharmacist for advice.

Warning ! Care should be taken when consuming dried lactuca virosa, as you cannot control the dose and may consume more than you think.

In addition, there is no way to know if the dried herbs have been contaminated with pesticides, heavy metals, chemical fertilizers or other harmful substances, depending on the soil or the origin.
