HelloPharmacist Scorecard of Cascara Sagrada 450 mg by Botanic Choice

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

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 contains one active ingredient: cascara sagrada powder at 450 mg per capsule. Cascara sagrada is a stimulant laxative derived from the bark of a buckthorn shrub; it works by increasing muscle contractions in your colon to move stool along.

The capsule itself is made from gelatin and rice flour, which are inactive ingredients.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Cascara Sagrada's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: colon health.
  • We looked for evidence on: Constipation, Bowel preparation.
  • The closest evidence on file: Cascara Sagrada is rated "Possibly Ineffective" for Bowel preparation (Natural Medicines).
  • Also on file: Cascara Sagrada is rated "Insufficient Reliable Evidence To Rate" for Constipation.

Cascara sagrada is rated possibly ineffective for bowel preparation — the evidence doesn't support using it for that purpose. For constipation, the evidence we hold is insufficient to rate whether it works or doesn't.

What we do know from the safety notes is that it may help with short-term constipation, but it carries real risks, especially if you use it long-term.

The evidence, ingredient by ingredient Cascara Sagrada

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.

When used short-term and appropriately, cascara sagrada is generally well tolerated. The most common side effect is mild abdominal discomfort and cramps.

Rare serious effects include liver damage and, in the case of fresh or improperly aged bark, severe vomiting. Long-term use is where the real caution comes in.

Extended use can lead to low potassium levels, protein in your urine (albuminuria), blood in your urine (hematuria), and severe weight loss (cachexia). The safety data advises against cascara during pregnancy — stimulant laxatives are generally not recommended at that time.

If you're nursing, it's best avoided; active compounds may pass into breast milk.

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 — Cascara Sagrada.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 746 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.

Before you start cascara sagrada, check with your pharmacist if you take blood thinners (Coumadin), water pills (diuretics), corticosteroids, heart medications like digoxin, other stimulant laxatives, or any medications processed by your liver. All of these have documented interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Cascara sagrada may provide short-term relief for constipation, but it's not for regular or long-term use. If you take heart medications like digoxin, blood thinners like warfarin, water pills, or corticosteroids, you'll want to check with us before using this.

Talk to your pharmacist — especially if you're pregnant or nursing.
