HelloPharmacist Scorecard of Indigo by Hawaii Pharm

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

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: indigo extract. It's been used in traditional medicine, though the evidence base we have is thin.

The liquid also contains vegetable palm glycerin and alcohol as inactive ingredients.

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 data backs indigo extract as possibly effective for psoriasis — meaning there's some evidence, but it's not ironclad. For respiratory tract infections, prostate cancer, ulcerative colitis, hepatitis, and aging skin, the evidence isn't established well enough in our data to rate it either way.

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.

Indigo extract is generally well tolerated in the short term, the way it's traditionally used — but human safety data are limited, especially for longer periods. The safety data advise against it during pregnancy and while breastfeeding.

If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist about whether this is right for you.

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 for this ingredient in our data.

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.

This is worth considering if you're interested in a traditional approach to psoriasis and don't have pregnancy or breastfeeding concerns. Because the safety record is sparse and it's not been studied long-term in humans, talk it over with your doctor or pharmacist before you start — especially if you're managing other health conditions.

Indigo by Hawaii Pharm: Common Questions

Does Indigo by Hawaii Pharm interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Indigo. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Indigo 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.
Is indigo extract safe during pregnancy?
The safety data advise against it during pregnancy. There isn't enough reliable information to know it's safe, so talk with your doctor or pharmacist about your individual situation.
Can I take this while breastfeeding?
No — there's no reliable safety data for breastfeeding, so it's best to avoid it. Check with your doctor or pharmacist if you're looking for alternatives.
Does indigo extract actually work for psoriasis?
The evidence suggests it's possibly effective for psoriasis — meaning there's some support, but it's not definitive. Your results may vary, and it's not a first-line treatment.
How long can I safely take this?
Indigo has been used short-term in traditional medicine, but human safety data for longer use are limited. Talk with your doctor or pharmacist about how long it makes sense for you to use it.
What's in this liquid besides the active ingredient?
The product contains vegetable palm glycerin and alcohol as inactive ingredients to carry and preserve the extract.
