HelloPharmacist Scorecard of Black Walnut & Wormwood 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

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

This liquid contains 2 active ingredients: black walnut (fresh) and wormwood (fresh), combined in a proprietary blend. Black walnut has been used traditionally for circulatory health and wound support, though the strength of evidence for those uses isn't established.

Wormwood is traditionally used for digestive complaints and bile flow, again with evidence that's still being studied. The product also contains water and alcohol as inactive ingredients to hold these botanicals in liquid form.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Digestive and intestinal support.
  • We looked for evidence on: Crohn disease, Dyspepsia, Gastritis, Parasites, Intestinal health, Digestive complaints.
  • The closest evidence on file: Wormwood is rated "Insufficient Reliable Evidence To Rate" for Crohn disease (Natural Medicines).
  • Also on file: Wormwood is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Gastritis.

The evidence for what this product actually does isn't well established yet. Black walnut has been studied for heart health and wound healing, but we don't have reliable data showing it works for either.

Wormwood has been studied for digestive upset, bile-related conditions, depression, arthritis, and Crohn's disease, but again the evidence isn't solid enough to rate. Neither ingredient has strong proof behind it for any condition in our data.

The evidence, ingredient by ingredient Black Walnut Wormwood

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Black walnut is generally well tolerated when taken orally as the nut itself, but this product is a fresh preparation — meaning it likely contains the leaf, bark, or hull, which are high in tannins and can cause stomach upset. Tree nuts including black walnut are a major food allergen, so stop immediately if you have any allergic reaction.

During pregnancy, the safety data advises against black walnut; while breastfeeding, there isn't enough information to know either way — talk with your doctor or pharmacist. Wormwood carries more caution.

Short-term use of a properly prepared product may be acceptable, but the thujone it contains can be toxic at higher doses. It may cause nausea, vomiting, muscle aches, or — rarely — kidney damage or seizures.

Wormwood may also stimulate the uterus, so it's unsafe during pregnancy. While breastfeeding, there isn't enough safety data; talk with your doctor or pharmacist before using it.

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?
  • 1 of the 2 matched ingredients can interact with medications — Wormwood.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: seizure medications.
  • For scale: 50 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 an anticonvulsant (seizure medication), wormwood in this product may interfere with how it works — that's a Moderate-severity concern. Check your exact medication with the tool on this page before starting.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is best for someone interested in traditional herbal support who is not pregnant or breastfeeding and doesn't take seizure medication. If you take any prescription drugs — especially anticonvulsants — or you're expecting or nursing, check with your pharmacist first.

Long-term safety data for both of these herbs are limited, so short-term use under guidance is the safest approach.

Black Walnut & Wormwood by Red Moon Herbs: Common Questions

Does Black Walnut & Wormwood by Red Moon Herbs interact with any medications?
Yes. Based on its ingredients, Black Walnut & Wormwood has a known interaction with 50 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Black Walnut & Wormwood contains 2 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 or breastfeeding?
No — the data advises against both. Black walnut is unsafe during pregnancy, and wormwood may stimulate the uterus, which is also not safe in pregnancy. For breastfeeding, there isn't enough safety information for either ingredient to know either way. Talk with your doctor or pharmacist about whether this product is right for you.
What are the most common side effects?
Black walnut can cause stomach upset due to its tannin content. Wormwood may cause nausea, vomiting, muscle aches, and stomach problems. These are the most common issues people report when they use these herbs orally.
Does this product work for heart health or digestion?
The evidence isn't there yet. Black walnut has been studied for heart health and wormwood for digestive complaints, but we don't have reliable data showing either one actually works for those purposes.
Is this product safe for long-term use?
Human safety data are limited for both ingredients, and long-term use hasn't been well studied. Short-term, properly prepared use seems more acceptable — but talk with your pharmacist about how long you're planning to take it.
I'm allergic to tree nuts. Should I avoid this?
Yes. Black walnut is a tree nut and is a major food allergen. Stop immediately if you have any allergic reaction, and avoid this product if you have a known tree nut allergy.
What is thujone and why does it matter?
Thujone is a neurotoxin found in wormwood. In higher amounts it can be harmful — causing nausea, vomiting, and rarely serious problems like kidney damage or seizures. That's why properly prepared wormwood and short-term use are important.
