Does it work?

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: promotes restful sleep.
  • We looked for evidence on: insomnia, sleep quality, sleep onset.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We hold no effectiveness ratings for wild lettuce in our data, so the evidence for what it may do isn't established here.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Wild lettuce comes with important safety cautions. Limited human safety data exist, and high doses have been tied to side effects.

Large amounts—or prematurely harvested wild lettuce—have been reported to cause sweating, rapid breathing, rapid heartbeat, dizziness, ringing in the ears, vision problems, pressure in the head, sleepiness, agitation, slowed breathing, and in severe cases, coma or death. Topically, it can cause contact dermatitis (skin irritation).

The safety data advises against use during pregnancy and breastfeeding, so talk with your pharmacist or doctor if you're pregnant, trying to conceive, or nursing.

Anticholinergic Drugs

Studies report varying evidence on whether or not wild lettuce contains hyoscyamine, an anticholinergic drug. If it does, it appears to be in very low amounts. Nevertheless, there have been case reports of individuals consuming large amounts of wild lettuce experiencing anticholinergic-related side effects, such as constipation, dry mouth, dizziness, and sweating. Therefore, if you are already taking a drug with anticholinergic effects, you should be cautious about combining it with wild lettuce as the risk of side effects may be increased.
