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.
What’s inside
Full disclosure
This product contains one active ingredient: Indigo Leaf Extract, Dry — a concentrated form of indigo from the Isatis plant. It's a liquid formulation, so you're getting the extract suspended in alcohol, water, and glycerin.
Does it work?
Moderate evidence
Indigo Leaf Extract has possibly effective evidence for psoriasis — the strongest rating in the data we hold. For respiratory tract infections, prostate cancer, ulcerative colitis, hepatitis, and aging skin, the evidence isn't established enough to rate.
That doesn't mean it doesn't work; it means human studies are either limited or missing for those uses.
How safe is it?
Some data gaps
The main caution is that human safety data for indigo are limited, and traditional use has mostly been short-term. If you're pregnant, the safety data advise against it — talk with your doctor or pharmacist for personalized advice.
The same goes for breastfeeding: there isn't enough reliable data to know either way, so that's a conversation to have with your own healthcare provider. We hold no adverse effect reports in our data.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. That said, always let your doctor or pharmacist know you're taking this product so they can review it against your full medication list.
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 considering indigo for psoriasis, it may be worth exploring — the evidence leans possibly effective. If you're pregnant, breastfeeding, or have other health conditions, check with your doctor or pharmacist before starting.
No interactions are documented with the medications we could check, but your healthcare provider can confirm it fits your full picture.
