HelloPharmacist Scorecard of Cascara Sagrada & Buckthorn Mint Flavor by TerraVita

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

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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This liquid contains two active herbal extracts: cascara sagrada and buckthorn (sea buckthorn), both in glycerite form. Cascara sagrada is a traditional stimulant laxative — it works by encouraging bowel contractions.

Buckthorn is included here as sea buckthorn extract, which has different uses than cascara and is thought to support skin and general wellness. The inactive ingredients are glycerin (the liquid base) and mint flavor.

Does it work?

Leans against
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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: Constipation and bowel health support.
  • We looked for evidence on: Bowel preparation, Constipation, Bowel regularity, Digestive support.
  • 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.

For cascara sagrada, we have mixed data. It's rated possibly ineffective for bowel prep before procedures, and we don't have enough evidence to rate it for everyday constipation.

Buckthorn (sea buckthorn) is rated possibly effective for burns, but the evidence isn't established for skin aging, eczema, or cholesterol — and we hold no data on how well this particular formula works for any of these uses.

The evidence, ingredient by ingredient Cascara Sagrada Sea Buckthorn

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Short-term use of cascara sagrada is generally well tolerated, though mild cramping and abdominal discomfort are common. The real concern is long-term daily use — it can cause serious issues including liver damage, bleeding in the urine, and muscle wasting.

Fresh or improperly aged cascara can trigger severe vomiting. Buckthorn is generally well tolerated as a food, but supplement safety at the doses used here hasn't been fully studied; high doses can stain skin yellow.

The facts advise against cascara during pregnancy and rate it possibly unsafe while breastfeeding because active compounds may pass into breast milk. For buckthorn, there isn't enough reliable data on safety during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice.

Side effects, ingredient by ingredient Cascara Sagrada Sea Buckthorn

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Sea Buckthorn, 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: 905 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 taking this product, double-check with your pharmacist if you use a water pill (diuretic), corticosteroid, the heart drug digoxin, blood thinners like warfarin, antiplatelet drugs like aspirin, or blood pressure medication. You should also avoid combining it with other stimulant laxatives.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is a stimulant laxative best used short-term for occasional constipation, not as a daily habit. If you take any blood pressure medication, water pill, heart medication (especially digoxin), corticosteroid, or blood thinner, you need to check with us or your pharmacist before starting.

Avoid during pregnancy and breastfeeding.
