The bottom line No known interaction

We found no known interaction between Hydrangea and Colchicine 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.

Hydrangea and Colchicine

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 Colchicine and Hydrangea 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.

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.

Hydrangea safety at a glance

Hydrangea overall Use caution Human safety data are limited, and large or prolonged doses may cause unwanted effects.
Pregnancy Avoid Not enough safety information exists, so it is best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Colchicine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Colchicine is filed under 5 classifications — including antigout drugs, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Hydrangea has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Colchicine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Hydrangea Itself Has Been Linked To

This is not an interaction — nothing below involves Colchicine. It is the side-effect record for Hydrangea on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Hydrangea, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Hydrangea — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Colchicine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Colchicine column appears here.

From our pharmacist’s overview on the Colchicine page

“Colchicine, the gout and pericarditis medicine sold as Colcrys and Mitigare, has one of the smallest gaps between a helpful dose and a harmful one of any drug I dispense, so its 146 supplement interactions deserve genuine respect. Most of them work the same way, blocking or speeding up the enzyme and transporter (CYP3A4 and P-glycoprot…”

About Hydrangea

What is Hydrangea?

  • Kidney and bladder stones
  • Urinary tract complaints
  • Enlarged prostate symptoms
  • Mild diuretic (increasing urine)
  • Bladder infections (traditional use)

Hydrangea root has a long history in folk medicine, mainly for urinary and kidney stone complaints, but there is very little modern human research to confirm it works for any condition. Because safety data are limited and large amounts may be harmful, it is best to talk with a pharmacist or doctor before using it.

Hydrangea arborescens · Hydrangeaceae · Root and rhizome (underground stem) · Dried root, tincture, liquid extract, capsules, tea

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

Hydrangea: dosing

There is no well-established or standardized dose for hydrangea, because it has not been studied carefully in people. Traditional preparations used the dried root as a tea or tincture, but reliable, specific amounts are not available.If you choose to use a product, follow the directions on the label and do not exceed them.

Lodoco (colchicine tablet) is specifically indicated to reduce the risk of heart attack, stroke, coronary revascularization, and cardiovascular death in adults with established atherosclerotic disease or multiple cardiovascular risk factors.
