HelloPharmacist Scorecard of Watercress Non-Alcohol by Hawaii Pharm

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
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
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?
  • We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Ingredient Transparency
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
Known Interaction Concern
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Watercress.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 6 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Safety Information
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 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.

Assessment coverage: 1 of 1 active ingredient matched to our full ingredient reviews (monographs). Based on the product label dated Oct 23, 2020.

Each ingredient & the kinds of drugs it affects

For each ingredient in Watercress Non-Alcohol with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

certified organic Watercress extract3 drug types · 6 drugs

Chlorzoxazone (Parafon Forte, Paraflex)

Watercress might reduce the metabolism of chlorzoxazone and increase its effects and side effects. Clinical research in healthy volunteers shows that a single ingestion of watercress 50 grams increases the chlorzoxazone plasma concentration-time curve by about 56% and increases its half-life by about 53%.

Likelihood Probable Evidence B
Lithium

Watercress is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, watercress might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D
Warfarin (Coumadin)

Watercress contains vitamin K. Consuming large amounts of watercress might antagonize the anticoagulant effects of warfarin.
