HelloPharmacist Scorecard of Re-Leaf by Red Moon Herbs

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Oct 6, 2026

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 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Re-Leaf is a liquid blend with four active plant ingredients. Cramp Bark, California Poppy (fresh), Pedicularis (fresh), and Wild Lettuce (fresh) make up the formula — they're traditionally used for muscle tension and relaxation.

The liquid also contains alcohol and 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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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

The evidence we hold doesn't establish that any of these ingredients work for their traditional uses. Cramp Bark is used in folk medicine for muscle cramps, kidney stones, and menstrual discomfort, but we have insufficient reliable evidence to rate it for any of these.

California Poppy and Wild Lettuce are traditionally used for anxiety and sleep, but again, the evidence we hold rates both as insufficient to establish they work. This doesn't mean they don't — it means the clinical data we have on file isn't strong enough to confirm it.

The evidence, ingredient by ingredient Cramp Bark California Poppy 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 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Human safety data for all three checked ingredients are limited. California Poppy and Wild Lettuce are generally considered mild for short-term use, but both carry cautions.

When wild lettuce is used in large amounts or harvested too early, it's been linked to serious effects like dizziness, headache, and in rare cases coma and death — so dose and sourcing matter. When California Poppy was used with other herbs in one study, some people reported muscular stiffness, morning fatigue, and nausea, though it's unclear which ingredient caused them.

During pregnancy, the safety data advises against all three checked ingredients — Cramp Bark, California Poppy, and Wild Lettuce. The same goes for breastfeeding.

We hold no pregnancy or breastfeeding data for Pedicularis. Talk with your doctor or pharmacist before using this product if you're pregnant, nursing, or planning to be.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — California Poppy, Wild Lettuce.
  • The most serious interaction on file is rated Moderate.
  • For scale: 393 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take any sedating medications (CNS depressants) — including sleep aids, anti-anxiety drugs, opioids, and antihistamines — check with your doctor or pharmacist before adding this product; California Poppy and Wild Lettuce may increase drowsiness. Also double-check if you're on anticholinergic drugs (for overactive bladder, nausea, or other conditions) because of Wild Lettuce's potential interaction.

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.

Re-Leaf is marketed for relaxation, but we don't have reliable evidence that its ingredients work for that. More importantly, if you take sedating drugs — sleep aids, anxiety meds, opioids, antihistamines — or anticholinergic medications, you need to check your exact list with your doctor or pharmacist before starting this.

All three checked ingredients have limited human safety data, so this isn't a first-choice product for most people.

Wild Lettuce, Fresh2 drug types · 393 drugs

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.

Re-Leaf by Red Moon Herbs: Common Questions

Does Re-Leaf by Red Moon Herbs interact with any medications?
Yes. Based on its ingredients, Re-Leaf 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?
Re-Leaf contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this while pregnant?
No — the safety data advises against all three checked ingredients during pregnancy. There isn't enough data on Pedicularis. Talk with your doctor or pharmacist about what's safe for you.
Is this safe to breastfeed on?
The safety data advises against Cramp Bark, California Poppy, and Wild Lettuce while breastfeeding. We have no data on Pedicularis. Ask your doctor or pharmacist before using this product if you're nursing.
Can I take this with my sleep medication?
You'll need to check with your doctor or pharmacist first. Both California Poppy and Wild Lettuce may add to the drowsiness of sleep aids and other sedating drugs, which could be unsafe at your dose.
What side effects might happen?
Information is limited. When California Poppy was combined with other herbs in one study, some people reported morning fatigue, stiffness, and nausea — though it's unclear which ingredient caused them. Large amounts of wild lettuce can cause dizziness, headache, and nausea.
Does this actually work for muscle cramps?
We don't have reliable evidence it does. Cramp Bark is used that way in traditional medicine, but the clinical data we hold isn't strong enough to confirm it works.
What is California Poppy used for?
It's traditionally used for anxiety and insomnia, but the evidence we hold isn't strong enough to say whether it actually works for either. It does have sedative effects in the lab.
