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.

We don't have effectiveness ratings on file for wild lettuce. The evidence supporting its use isn't established in our data, so we can't tell you how well it actually 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 comes with important safety cautions. Limited human safety data exist, and high doses have been linked to side effects.

In large amounts or if harvested prematurely, wild lettuce can cause sweating, increased breathing, rapid heart rate, dilated pupils, dizziness, ringing in the ears, vision problems, head pressure, drowsiness, excitatory states, slowed breathing, and in severe cases, coma or death. Topically, it can trigger contact dermatitis (a skin rash).

The safety data advises against use during pregnancy and while breastfeeding—there isn't enough information to know it's safe in either situation.

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

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Wild lettuce is a traditional herbal product with limited human safety research and a documented potential to interact with sedating drugs and anticholinergic medications. If you take anything for sleep, anxiety, or pain, or any medication that affects nerve signals, talk with your pharmacist before adding this.

Pregnancy and breastfeeding require a conversation with your doctor or pharmacist.

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.

Wild Lettuce by Hawaii Pharm: Common Questions

Does Wild Lettuce by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Wild Lettuce has a known interaction with 393 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wild Lettuce contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Wild Lettuce if I'm pregnant or breastfeeding?
No. The safety data advises against use during pregnancy, and there's no reliable safety information for breastfeeding, so it's best avoided in both situations. Talk with your doctor or pharmacist about what's safe for you.
What are the side effects of Wild Lettuce?
In large amounts or with prematurely harvested material, wild lettuce can cause sweating, increased breathing, rapid heart rate, dizziness, ringing in ears, vision problems, head pressure, drowsiness, and in severe cases, serious respiratory problems or coma. Topically, it may cause a skin rash. Limited safety data exist overall, and high doses carry real risks.
Is this product FDA-approved?
Herbal supplements like this one are not FDA-approved the way medications are. The facts on file don't cover regulatory approval status—your pharmacist can discuss how supplements are regulated and what that means for this product.
What is Wild Lettuce used for?
The facts on file don't specify what wild lettuce is traditionally used for. We know it's a plant-based herbal remedy, but we don't have effectiveness data to back any specific purpose. Ask your pharmacist or the product label what it's intended to support.
Can I take this with my sleep aid or anxiety medication?
Not safely without checking first. Wild lettuce has a documented moderate-severity interaction with CNS depressants—drugs that make you drowsy or calm. Combining them could cause too much sedation and other unwanted effects. Run your exact medications through the checker on this page or ask your pharmacist.
