The bottom line No known interaction

We found no known interaction between Hu Zhang and Nabumetone 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.

Hu Zhang and Nabumetone

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 Nabumetone and Hu Zhang 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.

Hu Zhang safety at a glance

Hu Zhang overall Use caution Generally used in traditional medicine, but human safety data for supplements are limited and its emodin content may cause digestive upset.
Pregnancy Avoid Not enough safety data and some compounds may affect the uterus or bowel, so it is best avoided.
Breastfeeding Avoid There is not enough safety information, 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 Nabumetone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nabumetone is filed under 6 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Hu Zhang has documented interactions with 7 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2c19 (cyp2c19) substrates (moderate) — and none of Nabumetone’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 Nabumetone’s Own FDA Label Lists

This is not an interaction — none of it involves Hu Zhang. These are the most notable effects listed in the ADVERSE REACTIONS section of Nabumetone’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on
  • Trouble swallowing Worth acting on
  • Bleeding in the gut Worth acting on
  • Low potassium Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on

Showing the 10 most notable of 64 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Nabumetone. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,395 voluntary FDA FAERS reports for Nabumetone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Hu Zhang’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hu Zhang side to compare — that is a limit of the record, not a statement that Hu Zhang has no side effects.

Overlapping uses

What Nabumetone Is Prescribed For, and What Hu Zhang Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Nabumetone is a prescription medicine with approved uses on its FDA label. Hu Zhang is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Nabumetone is prescribed for: Nabumetone tablets — available as generic nabumetone and as the brand Relafen DS — are used to relieve pain, swelling, and stiffness caused by osteoarthritis and rheumatoid arthritis. It is meant to be used at the lowest effective dose for the shortest time needed. It is not approved for pain relief around coronary artery bypass graft (CABG) heart surgery.

Hu Zhang has been studied for:

  • Osteoarthritis studied, not established Hu Zhang has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Hu Zhang for osteoarthritis

    Although there has been interest in using oral hu zhang for osteoarthritis, there is insufficient reliable information about the clinical effects of hu zhang for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Nabumetone on your own; if you are taking Hu Zhang for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Nabumetone

This page covers Hu Zhang only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nabumetone page lists 52 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Siberian Cocklebur (major) and Wine (major).

By severity: 5 major · 35 moderate · 12 minor.

From our pharmacist’s overview on the Nabumetone page

“Five of the 52 supplement and herbal ingredients on file for nabumetone (Relafen) rate major, and those five are where real vigilance belongs. Nabumetone is an NSAID taken for arthritis and joint pain, and NSAIDs already stress the stomach and the kidneys, so the worst pairings hit exactly those weak spots.”

About Hu Zhang

What is Hu Zhang?

  • Source of resveratrol
  • Heart and circulation support
  • Inflammation
  • Liver and digestive complaints (traditional)
  • Cough and respiratory symptoms (traditional)
  • Skin and joint conditions (traditional topical use)

Hu Zhang (Japanese knotweed root) is a traditional Chinese herb that is one of the richest natural sources of resveratrol and emodin. Some lab and early human research looks interesting for inflammation and heart health, but high-quality evidence in people is limited. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Reynoutria japonica · Polygonaceae · Root and rhizome · Capsules, tablets, powder, tincture, dried root for tea (decoction), standardized resveratrol extracts

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

Hu Zhang: dosing

There is no well-established standard dose of Hu Zhang. Products vary widely in strength, and some are standardized to a certain percentage of resveratrol while others are not.Because doses differ so much between products, the safest approach is to follow the directions on the label of the specific product you have.

Taking Hu Zhang and Nabumetone Together: Common Questions

Is it safe to take Hu Zhang with Nabumetone?
We do not list a known interaction between Hu Zhang and Nabumetone. 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.
Are Hu Zhang and Nabumetone used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Hu Zhang in each. That is a conversation for your prescriber, especially if Nabumetone is being adjusted to a target.
How was the Hu Zhang and Nabumetone combination checked?
Interactions in our licensed database are recorded against drug classes. Nabumetone is filed under 6 classifications, and Hu Zhang has documented interactions with 7 drug classes — none of Nabumetone's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Hu Zhang interact with any other medications?
Yes. Hu Zhang has 826 documented drug interactions in our database — Nabumetone is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Nabumetone interact with any supplements?
Yes. Nabumetone has documented interactions with 52 supplements in our database — Hu Zhang is not one of them. The Nabumetone interaction page linked on this page lists every one, ranked by severity.
