The short answer
Not known for triphala added to a separate laxative. Triphala is itself used as a laxative, so taking it with bisacodyl, senna, lactulose or isabgol means two products acting on the bowel. The only human study we found tested a ready-made powder of triphala, senna and isabgol in 34 people with constipation in Mumbai, and weekly bowel movements rose from about 10 to 18 over two weeks.
That study had no comparison group, and it cannot show what triphala adds to a laxative you already take. An effect that is too strong could mean diarrhoea and dehydration. If you use a laxative regularly, or a doctor prescribed one, tell them before you add triphala.
Laxatives sold in India include Dulcoflex (bisacodyl), Duphalac (lactulose) and Pegmove (polyethylene glycol).
At a glance
| What was seen | How it may work | Direction | Evidence |
|---|---|---|---|
| More bowel movements with a triphala, senna and isabgol powder[1] | Overlapping effects on the bowel; triphala's own share unknown | Could add to the effect of another laxative | Small clinical study |
| Triphala used as a laxative in its own right[2] | Laxative action described in Ayurvedic use and research | Could add to another laxative's effect; size unknown | Theoretical by mechanism |
No listing is not a clearance. A missing interaction here never means a combination is safe.
The evidence, study by study
Open study in constipation, Mumbai, 2011 Small clinical study
Thirty-four people with long-term (functional) constipation took TLPL/AY/01/2008, a branded powder of isabgol husk, senna extract and triphala extract, for 14 days. Weekly bowel movements rose from about 10 to 18, stools became softer and time on the toilet fell. There was no comparison group, and senna and isabgol are laxatives by themselves, so triphala's part cannot be separated out. The abstract does not give the dose.[1]
Review, United States, 2017 Theoretical by mechanism
A review from UC San Diego and the Chopra Foundation describes triphala, made from the fruits of amalaki, bibhitaki and haritaki, as a cornerstone of gut treatment in Ayurveda, with laxative action first among its researched uses. It is a narrative review and does not look at triphala taken with other laxatives.[2]
What your doctor may watch for
- Loose stools or diarrhoea, and signs of dehydration such as feeling dizzy or passing little urine.
What to tell your prescribing doctor
You can read this out, or show them this page:
“I am taking, or planning to take, triphala (name of product, dose) along with my laxative (name). Triphala is used as a laxative itself. Is it sensible to take both, and what should I watch for?”

Questions people ask
Can I take triphala with Dulcolax?
We found no study of triphala with bisacodyl, the medicine in Dulcolax and Dulcoflex. Both act on the bowel, so their effects could add up. Ask your doctor before combining them.[2]
What about triphala and senna tea together?
The one human study used a ready-made powder that included senna, and bowel movements nearly doubled. It cannot tell you how a home-made tea of your own will act.[1]
Does taking them at different times help?
No study we found tested timing, so there is no evidence that spacing them apart changes anything.[1]

Three fruits in one powder, best known as a laxative. Human trials are few and small; most research is in the lab or in animals.

No study in people has tested triphala's effect on other medicines, or any timing gap. In rats, triphala raised the levels of two test drugs.
