HelloPharmacist Scorecard of Woad Sugar Free Alcohol Free by Herbal Terra

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.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: woad leaf extract, derived from the woad plant. It's a traditional herb that's been used in folk medicine for various conditions.

The liquid also contains glycerin and water as inactive ingredients to deliver the extract.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Isatis's overall clinical evidence instead.

Moderate

Some clinical evidence supports Isatis for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Psoriasis — rated "Possibly Effective" (Natural Medicines).

The evidence for woad leaf extract is mixed and mostly sparse. It's rated possibly effective for psoriasis — the one condition with some supporting data — but for respiratory tract infections, prostate cancer, ulcerative colitis, hepatitis, and aging skin, the evidence is insufficient to draw any real conclusion.

We simply don't have solid trials to say whether it works for those uses.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Woad leaf extract has been used short-term in traditional medicine, but human safety data are limited, so caution is warranted. The safety information during pregnancy is not adequate — the data advises against using it while pregnant.

Similarly, there is no reliable safety data for breastfeeding, so it's best avoided if you're nursing. No adverse effects are listed in the data we hold, but the limited research means side effects could still occur.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for woad leaf extract. Still, because human safety information is limited, it's worth double-checking this product with your pharmacist if you take any medications or have health concerns.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and some safety-information gaps remain.

If you're interested in woad for psoriasis, there's a modest reason to consider it, but the evidence is weak. Anyone pregnant or breastfeeding should not use this product.

Because human safety data are limited overall, talk with your pharmacist or doctor before starting, especially if you have a health condition or take other supplements.

Woad Sugar Free Alcohol Free by Herbal Terra: Common Questions

Does Woad Sugar Free Alcohol Free by Herbal Terra interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Woad Sugar Free Alcohol Free. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Woad Sugar Free Alcohol Free 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.
Does this work for psoriasis?
Woad leaf extract is rated possibly effective for psoriasis, which means there's some evidence it may help — but the research is far from conclusive. It's not a proven treatment, so talk with your doctor about whether to try it alongside your current plan.
Can I use this if I'm pregnant?
No. There isn't enough safety information about woad during pregnancy, so the data advises against it. If you're pregnant or planning to be, skip this product and speak with your doctor about safer options.
Is it safe while breastfeeding?
No. There is no reliable safety data for woad while breastfeeding, so you should avoid it. Talk with your pharmacist or doctor about alternatives if you're nursing.
What are the side effects?
Our data don't list any adverse effects for woad leaf extract. That said, human safety research is limited, so side effects could still occur. If you notice any unusual symptoms after starting, stop and call your pharmacist.
How long can I use this?
Woad has traditionally been used short-term, and because safety data are limited, we don't have clear guidance on long-term use. Use it briefly and check in with your pharmacist if you want to continue beyond a few weeks.
What is woad?
Woad is a plant used for centuries in traditional medicine, especially in European and Asian folk practices. The extract in this product comes from the woad leaf and has been studied for a few conditions, though most evidence is thin.
