No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Stone Root and Alosetron in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Stone Root and Alosetron

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Alosetron and Stone Root in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Stone Root at all — not against Alosetron, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

No Interaction Found — But Data Suggests Stone Root and Alosetron May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

From our pharmacist’s overview on the Alosetron page

“Alosetron (Lotronex) treats severe diarrhea-predominant IBS by acting on serotonin receptors in the gut, and that is where most of its 38 supplement interactions come from. Twenty of the ingredients, 5-HTP among them, raise serotonin on their own, and stacking them on a serotonin-acting drug is a combination I want you to treat with re…”

About Stone Root

What is Stone Root?

Stone Root
  • Hemorrhoids
  • Urinary and bladder discomfort
  • Digestive upset
  • Sore throat and hoarseness
  • Kidney stones (traditional)

Stone root is a North American herb traditionally used for hemorrhoids, urinary complaints, and digestive issues. There is very little modern scientific evidence to confirm it works for any of these uses, so it should be viewed as a traditional remedy rather than a proven treatment. Talk with your pharmacist or doctor before trying it, especially if you are pregnant, breastfeeding, or take other medicines.

Collinsonia canadensis · Lamiaceae · Root and rhizome · Tincture, capsules, dried root for tea, liquid extract

An interaction check asks whether these two react with each other — it does not ask whether Stone Root is a good idea for someone in your situation. Here is what our Stone Root record says about it on its own.

Stone Root: dosing

There is no established standard dose for stone root. Traditional preparations include teas made from the dried root and alcohol-based tinctures, but reliable dosing guidelines from clinical studies do not exist.The safest approach is to follow the directions on the product label and not exceed them.

Taking Stone Root and Alosetron Together: Common Questions

Is it safe to take Stone Root with Alosetron?
We do not list a known interaction between Stone Root and Alosetron. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Stone Root and Alosetron have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Alosetron interact with any supplements?
Yes. Alosetron has documented interactions with 38 supplements in our database — Stone Root is not one of them. The Alosetron interaction page linked on this page lists every one, ranked by severity.
