HelloPharmacist Scorecard of Culver's Root Non-Alcohol 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

Low disclosure
Ingredient Transparency · database check
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.

This product contains one active ingredient: certified organic Culver's Root extract (also known as black root). Black root is a plant extract traditionally used for its laxative properties.

The liquid also includes vegetable palm glycerin and Hawaiian artesian water as inactive ingredients.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Black Root product and its label doesn't state a use — see Black Root's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The product facts we hold contain no effectiveness ratings for black root. We cannot tell you from our data whether it works for any intended use.

The evidence, ingredient by ingredient Black Root

How safe is it?

Well-documented data
Safety Information · database check
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.

Black root can cause abdominal pain or cramps, nausea, vomiting, headache, drowsiness, and changes in stool color or odor. Large amounts have been linked to liver damage (hepatotoxicity).

Modern safety data are limited, and the fresh root can cause significant digestive toxicity. The safety data advise against using this product during pregnancy because of its strong laxative effect and lack of safety information.

Avoid it while breastfeeding as well — there isn't enough data to know it's safe.

Side effects, ingredient by ingredient Black Root

certified organic Culver's Root extract3 drug types · 78 drugs

Digoxin (Lanoxin)

Theoretically, the overuse or abuse of black root can increase the risk of adverse effects of cardiac glycoside drugs. Black root chemically binds with the glycosides while in the gastrointestinal (GI) tract, which may reduce their effectiveness if used concomitantly.

Likelihood Probable Evidence D
Diuretic Drugs

Overuse of black root might compound diuretic-induced potassium loss.There is some concern that people taking black root along with potassium depleting diuretics might have an increased risk for hypokalemia. Initiation of potassium supplementation or an increase in potassium supplement dose may be necessary for some patients. Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Black root has stimulant laxative effects. In some people black root can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of black root.
