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

This is a single-ingredient Wild Lettuce product and its label doesn't state a use — see Wild Lettuce's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

We don't have effectiveness data on file for wild lettuce leaf extract. The science on what this product can actually do isn't established in our records, so we can't tell you whether it works for any particular purpose.

The evidence, ingredient by ingredient Wild Lettuce

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

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 has limited human safety data. The main caution is that high doses carry real risks.

Large amounts—or prematurely harvested wild lettuce—can cause sweating, rapid heartbeat, dizziness, ringing in the ears, vision problems, pressure in the head, drowsiness, and in severe cases, breathing trouble or coma. Small amounts applied to skin can trigger contact dermatitis (a rash).

During pregnancy, there isn't enough safety information, so it's best to avoid it. The same goes for breastfeeding—reliable safety data doesn't exist, so skip it while nursing.

Talk with your pharmacist or doctor before using this if you're pregnant, planning to become pregnant, or breastfeeding.

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.

Cns Depressants

Theoretically, concomitant use with drugs with sedative effects might cause additive therapeutic effects and adverse effects.
