Wild Lettuce Aerial Parts Extract

Also known as: Wild Lettuce, Opium Lettuce, Bitter Lettuce, _Lactuca virosa_

Overview

Wild Lettuce (_Lactuca virosa_) is a plant from the Asteraceae family native to Europe and Asia, recognized for its bitter leaves and milky sap. This herbal extract has a long history of traditional medicinal use, especially for its sedative and analgesic properties. It contains several bioactive compounds, including lactucarium, which contributes to its effects. While there is growing interest in its medicinal potential, research remains limited, predominantly comprising animal studies and smaller human trials. This leaves a knowledge gap regarding its efficacy and safety, necessitating further investigation into its applications.

Benefits

The primary benefits of Wild Lettuce include its sedative and anxiolytic properties, with animal studies indicating a sleep-enhancing effect and reduction in anxiety at doses starting from 10 mg/kg. Other less-studied benefits include potential analgesic effects and antioxidant activity based on related plants in the Asteraceae family. However, clinical significance is not well-established due to the predominance of short-term, small-scale studies. While the general population may experience sleep and anxiety improvements, data on specific demographics, such as the elderly or individuals with chronic conditions, is sparse.

How it works

The sedative and anxiolytic effects of Wild Lettuce are primarily linked to interactions with the GABAergic and serotonergic systems, similar to other sedative herbs. These interactions may modulate neurotransmitter levels, leading to decreased anxiety and improved sleep. Specific molecular targets remain undefined, and there is limited information on the extract's absorption and bioavailability, which could influence its effectiveness.

Side effects

Wild Lettuce is generally regarded as safe when consumed in moderation. Common side effects, occurring in more than 5% of users, include drowsiness and dizziness. Less common side effects, affecting 1-5% of users, can involve allergic reactions or gastrointestinal upset. Rare side effects have not been extensively documented, but as with any herbal product, there is a risk of allergic reactions. Caution is advised for individuals taking sedatives, antidepressants, or other CNS depressants, and it is contraindicated for pregnant or breastfeeding women. Special considerations are warranted for the elderly or those with chronic health problems due to the possibility of drug interactions.

Dosage

The effective dosage of Wild Lettuce has not been firmly established for humans, with animal studies suggesting a range of 10-50 mg/kg for sedative effects. Traditional applications often recommend doses of 1-5 grams of dried herb daily. While there is no defined maximum safe dose, exceeding 5 grams per day is not advised due to a lack of supporting data. The extract is best taken before bedtime to leverage its sedative properties, and it is available in several forms, including capsules, teas, and tinctures, which may affect absorption.
