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.

Herbal Hills Senna is a single-ingredient capsule containing a blend of senna leaves extract and senna leaves powder. Senna is a plant-based stimulant laxative — it works by encouraging your bowel to contract and move stool through faster.

The capsule itself is made from HPMC (a plant-based capsule material) and silicon dioxide, an inactive ingredient.

Does it work?

Strong evidence
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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: short-term constipation relief and bowel regularity.
  • We looked for evidence on: Bowel preparation, Constipation.
  • The strongest evidence on file: Senna is rated "Likely Effective" for Constipation (Natural Medicines).
  • Also on file: Senna is rated "Possibly Effective" for Bowel preparation.

Senna is Likely Effective for treating constipation when used as directed. It's Possibly Effective for bowel preparation — the cleansing doctors recommend before certain medical procedures.

The evidence isn't established for using senna to treat high potassium levels (hyperkalemia).

The evidence, ingredient by ingredient Senna

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.

Senna is generally well tolerated when you use it short-term in the right dose, but it's not meant for daily long-term use without your doctor's approval. The most common side effects are abdominal pain and cramps, diarrhea, gas, nausea, and urgent bowel movements; some people also notice their urine changes color.

Rarely, skin reactions such as rashes or severe blistering have been reported. Excessive use over weeks can cause more serious problems including finger clubbing and muscle weakness (tetany).

In pregnancy and while breastfeeding, senna is rated Possibly Safe based on available data, but because the evidence is limited, you should talk with your doctor or pharmacist before using it if you're pregnant or nursing.

Senna leaves extract & Senna leaves powder Blend5 drug types · 140 drugs

Digoxin (Lanoxin)

Theoretically, senna might increase the risk of adverse effects when taken with digoxin.
Overuse/abuse of senna increases the risk of adverse effects from cardiac glycosides, such as digoxin, due to potassium depletion.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, senna might increase the risk of hypokalemia when taken with diuretic drugs.
Overuse of senna might compound diuretic-induced potassium loss and increase the risk for hypokalemia.

Likelihood Possible Evidence D
Estrogens

Theoretically, taking senna may interfere with the absorption of exogenous estrogens.
Some preliminary clinical evidence suggests that senna reduces the absorption of estradiol and decreases serum concentrations of estrone and estrone sulfate by decreasing intestinal transit time.

Likelihood Possible Evidence B
Stimulant Laxatives

Theoretically, senna might increase the risk for fluid and electrolyte loss when taken with other stimulant laxatives.
Senna is a stimulant laxative; concomitant use with other stimulant laxatives might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, excessive use of senna might increase the effects of warfarin.
Senna has stimulant laxative effects and can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. In one case report, excessive use of senna for 3 weeks resulted in diarrhea, bloody stools, and an elevated INR of 11.9.

Senna by Herbal Hills: Common Questions

Does Senna by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Senna has a known interaction with 140 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Senna contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I use senna every day for constipation?
No — senna is meant for short-term occasional use only. Long-term daily use without medical advice is not recommended. If you're constipated regularly, talk with your doctor or pharmacist about safer ongoing options.
Will senna make my birth control less effective?
Possibly. Senna can interfere with how your body absorbs estrogens in birth control pills and hormone therapies, which may reduce their effectiveness. If you take hormonal birth control, check with your pharmacist or doctor before using senna.
What are the most common side effects?
Abdominal cramps, pain, diarrhea, gas, nausea, and urgent bowel movements are normal. Your urine may also change color. These usually ease once you stop taking it.
Is senna safe to use while I'm pregnant or breastfeeding?
Senna is rated Possibly Safe in pregnancy and while breastfeeding, but the evidence is limited. Talk with your doctor or pharmacist before using it if you're pregnant or nursing — they can advise you on whether it's right for your situation.
Can I take senna if I'm on a water pill (diuretic)?
Not without checking first. Senna can increase the risk of low potassium levels when combined with diuretics, especially if you overuse it. Ask your doctor or pharmacist before combining them.
What if I take warfarin — can I use senna?
You need to check with your doctor first. Senna can cause diarrhea, which increases how warfarin works and raises your bleeding risk. A case report documented this after excessive use for 3 weeks.
