We found no known interaction between Hercules Club and Pemetrexed in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Hercules Club and Pemetrexed

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 Pemetrexed and Hercules Club 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.

How we checked

Why No Interaction Is Listed for Pemetrexed

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pemetrexed is filed under a single classification — organic anion transporter 3 (oat3) substrates. Hercules Club has documented interactions with 3 drug classes — the most serious being antacids (minor), h2-blockers (minor) and proton pump inhibitors (ppis) (minor) — and none of Pemetrexed’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 Pemetrexed’s Own FDA Label Lists

This is not an interaction — none of it involves Hercules Club. These are the most notable effects listed in the ADVERSE REACTIONS section of Pemetrexed’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.

  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • High blood sugar Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on

Showing the 10 most notable of 22 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 Pemetrexed. Read the label on DailyMed › Hercules Club’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hercules Club side to compare — that is a limit of the record, not a statement that Hercules Club has no side effects.

From our pharmacist’s overview on the Pemetrexed page

“Every supplement on file for pemetrexed (Alimta, Pemfexy) works the same way. Each can slow how the kidneys pull the drug out of the blood, which would let it linger and build to higher levels than intended.”

About Hercules Club

What is Hercules Club?

Hercules Club
  • Toothache and mouth pain
  • Indigestion and sluggish digestion
  • Rheumatism and joint pain
  • Circulation (as a stimulant or tonic)
  • Sore throat

Hercules Club (southern prickly ash) is a traditional folk remedy used mainly for toothache, digestion, and joint pain, often by chewing the bark, which causes a tingling, numbing feeling in the mouth. Modern scientific evidence supporting these uses is very limited, and safety has not been well studied, so it is best to talk with a pharmacist or doctor before using it.

Zanthoxylum clava-herculis · Rutaceae · Bark, roots, and berries · Dried bark, tinctures, teas, and topical preparations

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

Hercules Club: dosing

There is no established standardized dose for Hercules Club. Traditional use varied widely, and product strengths differ from one brand to another.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

It is not used for squamous cell non-small cell lung cancer.
