Prickly lettuce is unlike farmed lettuce, which is tender and milky, just as it is used in salads; however, it lacks practically any medicinal properties. Instead, it is a valuable remedy used in ancient times when it is green, wholly grown, and mature (wild lettuce is even better).
- OUTSTANDING VALUE / 120 DOSAGES: Our Extra Strength Wild Lettuce Extract contains 1500 mg strength per capsule AND 120 capsules per bottle – an amazing value! A single bottle contains a 4 month supply. Compare this to other leading brands that require 2 capsules per serving, contain less than 120 capsules, are not derived from the superior Lactuca Virosa of Wild Lettuce, and use a much less potent, non-extract powder. Our Extra Strength Wild Lettuce Extract is a bargain not be found elsewhere!

Healing Properties and Uses
The leaves of prickly lettuce contain chlorophyll, mineral salts, vitamins, and a bitter substance. However, the active components that act on the nervous system are found in the milky latex, which springs from the plant’s stems when cut. Lactucarium is obtained from this latex by employing a process called solidification.
Prickly lettuce leaves, and especially latex, have the following properties:
- Sedative, similar to opium, though unlike this, lettuce does not have any toxic effect so that it may be used even with children. In this way, it calms excessive activity and eases sleep.
- Anaphrodisiac. It helps control sexual excitation. Dioscorides said that “it stops wet dreams and represses the disorderly appetite for fornication.”
- Antitussive. Lettuce is especially recommended for irritant coughs and whooping cough.
