HelloPharmacist Scorecard of Ban Lan Gen 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 has one active ingredient: isatis tinctoria root extract (also called Ban Lan Gen), a traditional remedy with a long history in herbal medicine. The inactive ingredients are alcohol, water, and glycerin, which help preserve and 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 isatis tinctoria is patchy. It's rated possibly effective for psoriasis — meaning there's some support, but it's not airtight.

For respiratory tract infections, prostate cancer, ulcerative colitis, hepatitis, and aging skin, the evidence we hold isn't strong enough to rate it one way or the other. If you're considering it for any of those other uses, that's a conversation to have with your doctor or pharmacist.

The evidence, ingredient by ingredient Isatis

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.

Isatis tinctoria has been used short-term in traditional medicine, but human safety data are limited — we don't have a lot of solid information on how it behaves in real people over time. The safety data advises against use during pregnancy and while breastfeeding, so if you're pregnant, planning to become pregnant, or nursing, skip this product and talk with your doctor about other options.

No adverse effects are documented in the data we hold, though that's not a guarantee none could occur.

Side effects, ingredient by ingredient Isatis

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 the ingredient we could check. Run your current medications through the search tool on this page to be sure, and let your doctor or pharmacist know you're considering this product.

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.

Ban Lan Gen is a single-ingredient herbal extract with some traditional use and modest evidence for psoriasis. If you're interested in it for that purpose, and you're not pregnant or breastfeeding, it's reasonable to discuss with your doctor or pharmacist.

Because human safety data are limited, they can help you weigh whether it fits your situation and how long it's safe to take.
