What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

This product contains one active ingredient: selectively imported wild lettuce. Wild lettuce is a plant extract traditionally used as a herbal supplement.

The liquid also contains grain alcohol and deionized water as inactive ingredients.

Does it work?

Couldn't assess
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.

No effectiveness ratings are available in our data for wild lettuce. The evidence supporting its use has not been established in the records we hold.

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.

Mature, properly harvested wild lettuce taken by mouth is generally well tolerated. However, limited human safety data exist, and the facts note caution with high doses.

Large amounts of wild lettuce or prematurely harvested material have been linked to sweating, rapid breathing, rapid heartbeat, dizziness, ringing in the ears, vision changes, head pressure, sleepiness, restlessness, and in rare severe cases, breathing depression and coma. Topically, wild lettuce can cause contact dermatitis (skin irritation) in susceptible people.

The safety data advises against use during pregnancy and while breastfeeding due to insufficient information.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Wild Lettuce.
  • The most serious interaction on file is rated Moderate.

Both can interact with wild lettuce at moderate severity.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Wild Lettuce by L.A. Naturals may be worth considering if you're interested in herbal supplements, but you'll want to be cautious if you take sedatives, sleep aids, anxiety medications, or anticholinergic drugs — the risk of additive effects is real.

Pregnant or breastfeeding? The data doesn't support using it.

Before you start, run it past your doctor or pharmacist, especially if you're on any prescription medications.

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.

What does wild lettuce do?
