Stone Root + Papaverine
Papaverine brand names: Pavabid, Para Time, P 200, Pavabid HP.
We found no known interaction between Stone Root and Papaverine 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 Papaverine
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 Papaverine 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 Papaverine, 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.

See Every Supplement That Interacts With Papaverine
This page covers Stone Root only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Papaverine page lists 20 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), American Mistletoe (major), Beer (moderate), Coffee Charcoal (moderate) and European Mandrake (moderate).
By severity: 2 major · 9 moderate · 9 minor.
From our pharmacist’s overview on the Papaverine page
“Papaverine relaxes blood vessels to improve blood flow, and its interaction list warrants genuine care, since 2 of the 20 entries are rated major. Most of the list concerns absorption, fibers and gums that can change how much of an oral dose reaches your bloodstream, but the two majors come first.”

About Stone Root
What is 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.

About Papaverine
What Is Papaverine Used For?
Brand names: Pavabid, Para Time, P 200, Pavabid HP
Papaverine Hydrochloride Injection is used when smooth muscle goes into spasm — meaning it contracts abnormally and needs to be relaxed. It is given for vascular (blood vessel) spasms that can occur with conditions like acute myocardial infarction (heart attack), angina pectoris (chest pain from reduced blood flow to the heart), and peripheral or pulmonary embolism (blockages in the limb or lung arteries).
It is also used for peripheral vascular disease where spasm plays a role, certain cerebral angiospastic states (blood vessel spasms in the brain), and visceral spasm — meaning painful cramping in internal organs such as the ureter, gallbladder (biliary colic), or intestines (gastrointestinal colic).
