HelloPharmacist Scorecard of Woad 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: woad extract, a plant-based compound. Woad is a traditional herbal remedy with a long history in folk medicine, though modern research on it is still developing.
Does it work?
Insufficient evidence
The evidence is mixed. Woad extract is possibly effective for psoriasis based on available data.
For respiratory tract infections, prostate cancer, ulcerative colitis (inflammatory bowel disease), hepatitis, and aging skin, we don't yet have enough reliable evidence to rate how well it works.
How safe is it?
Some data gaps
Woad extract has been used short-term in traditional medicine, but human safety data are limited—so we don't have a complete picture of how safe it is long-term. During pregnancy, there isn't enough safety information, so it's best avoided.
While breastfeeding, there's no reliable safety data either, so you should avoid it then too. No adverse effects were reported in our data, but that reflects limited research rather than proof it's completely risk-free.
Meds to double-check
No known interactions
No interactions are documented in our data for woad extract. Still, check your medications through the tool on this page to be sure, and let your doctor or pharmacist know you're thinking of taking this supplement.
The bottom line
Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
Woad extract may be worth considering if you're exploring options for psoriasis, though the evidence is modest. Because safety data in humans are sparse and it's not recommended in pregnancy or while breastfeeding, talk it over with your doctor or pharmacist before you start—especially if you're pregnant, nursing, or planning either.
