Wild Lettuce commonly refers to the bitter cousin of common garden lettuce is a biennial herb that belongs to the lactuca genus and the sunflower family. Its botanical name is Lactuca Virosa and is native to Europe. It is called by various names, such as Wild Lettuce, Bitter lettuce, Laitue vireuse, Opium Lettuce, Poisonous Lettuce, Tall Lettuce, Great Lettuce, Rakutu-Karyumu-So, compass plant, horse thistle, Prickly lettuce and wild opium. In Latin, Lactuca means ‘milky extract’ and Virosa means ‘toxic’.

Wild lettuce contains a type of bitter-tasting milky juice that can be extracted from almost any part of the plant. The leaves, seed and latex of this herb are used in herbal medicinal preparations. The fresh leaves can be added to salads, though be warned that the leaves are bitterer than typical salad greens. Once established, wild lettuce is a hardy plant and easy to maintain. It is a great relaxing and sedating herb that has been used for thousands of years. In fact, Roman emperor Augustus created a statue to a herbalist who recommended wild lettuce for his health problems. And in ancient Egypt, there was a wild lettuce harvest because this herb was well known for its healing qualities.

Plant Description

Wild lettuce is a biennial herb that grows about 200 cm high. It is found growing in grassy places by roads, canals etc and on banks near the sea, cracks in sidewalks, vacant lots and other waste places. It prefers moist, rich, well-draining soil. The plant has brown tap-root and erect stem is smooth and pale green, sometimes spotted with purple. There are a few prickles on the lower part and short horizontal branches above.

Leaves

Radical leaves are from 6 to 18 inches long, entire, and obovate-oblong and stem leaves are scanty, alternate, and small, clasping the stem with two small lobes.

Flower & Fruit

Small yellow flowers are around ¼ inch wide. Multiple flowers occur on a single plant. Flowering normally takes place from July until September. Later the plant produces rough, black fruit that is oval with a broad wing along the edge, and prolonged above into a long, white beak carrying silvery tufts of hair.

History

L. virosa was used in the 19th century by physicians when opium could not be obtained. It was studied extensively by the Council of the Pharmaceutical Society of Great Britain in 1911. They discovered two chemicals responsible for the properties of L. virosa; lactucopicrin and lactucin. In the United States, the plant experienced a resurgence in popularity in the 1970s. Today the plant is un-scheduled by the Food and Drug Administration (FDA), meaning it is legal to grow, purchase and own without prescription or license.

Health benefits of Wild Lettuce

Wild Lettuce is an herb which is not considered a vegetable like the common green lettuce. Wild lettuce is more popular for its “opium-like” effects due to its sedative and psychotropic properties. It is believed that the Ancient Greeks and Romans used this herb as a food crop. Wild Lettuce has a few health related benefits which include the following:

1. Helps to relieve pain

The action of compounds found in the lactucarium is similar to the action of morphine, which reduces the central nervous system, blunting its ability to feel the pain. Thus, wild lettuce is beneficial for solving colic pain, arthritic pain, muscle spasms, joint pain, muscle pain, and uterine cramps in women during the menstruation.

2. Hardening of arteries

Atherosclerosis is a condition in which the arteries become thick and stiff, by this means, blood pressure will increase and the blood flow to the organs and tissues will be restricted. This happens due to cholesterol, fats and other substances to get accumulated in the walls of arteries. The seed oil of wild lettuce helps to regain the flexibility and elasticity of the affected arteries.

3. Used in treatment of urinary tract problems

Natural diuretics are a safer alternative to diuretic medicines as they pose less or no side effects. Wild lettuce has diuretic property and can be used to treat urinary tract infections.

4. Used to treat respiratory issues

Wild lettuce can be used as a natural treatment for asthma and annoying coughs due to its antitussive properties. It helps to bring down the irritation of the bronchial tubes and lungs. It also facilitates the difficulty breathing associated with asthma. Besides, it can be an effective treatment for a whooping cough and bronchitis.

5. Helps to soothe stress and anxiety

Wild lettuce has a mild euphoric property. It is supposed to have properties which inhibit nervous system’s functions. Therefore, wild lettuce is used to soothe the stress and anxiety.

6. For the Skin

7. Helps with migraines and headaches

The tincture form of wild lettuce is also effective in getting rid of a headache.

8. To treat sexual disorders

Wild lettuce helps to hold back the sex drive. Therefore, it is used to treat nymphomania – uncontrollable and extreme sex drive in women.

9. Sedative

Pain relieving qualities of Wild Lettuce also help in relaxing the body. This makes it very useful in the treatment of insomnia and anxiety, with it also called feeble opium because it does not upset the digestive system.
