Chinese Prickly Ash and Losartan Potassium

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 Losartan Potassium and Chinese Prickly Ash 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.

Chinese Prickly As... overall Use caution Generally safe as a food spice, but medicinal-strength extracts are not well studied in people.

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

How we checked

Why No Interaction Is Listed for Losartan Potassium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Losartan Potassium is filed under 7 classifications — including angiotensin receptor blockers (arbs), cytochrome p450 2c9 (cyp2c9) substrates, antihypertensive drugs. Chinese Prickly Ash has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Losartan Potassium’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 Losartan Potassium’s Own FDA Label Lists

This is not an interaction — none of it involves Chinese Prickly Ash. These are the most notable effects listed in the ADVERSE REACTIONS section of Losartan Potassium’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.

  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on

Showing the 10 most notable of 44 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 Losartan Potassium. Read the label on DailyMed › Where a percentage is shown, it is the share of 89,498 voluntary FDA FAERS reports for Losartan Potassium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Chinese Prickly Ash’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Chinese Prickly Ash side to compare — that is a limit of the record, not a statement that Chinese Prickly Ash has no side effects.

About Chinese Prickly Ash

What is Chinese Prickly Ash?

  • Digestive upset and stomach pain
  • Toothache and oral numbing
  • Antimicrobial and antiparasitic use
  • Cooking spice (Sichuan pepper)
  • Mild pain relief

Chinese Prickly Ash is the fruit husk of Zanthoxylum bungeanum, best known as the Sichuan pepper that creates a tingling, numbing sensation on the tongue. It is widely used in cooking and traditional Chinese medicine for digestive complaints and pain, but strong human evidence for medicinal benefits is limited. Use culinary amounts safely, but talk to a pharmacist or doctor before using concentrated extracts.

Zanthoxylum bungeanum · Rutaceae · Dried fruit husks (pericarp), and sometimes the seeds and essential oil · Dried whole spice (Sichuan pepper), ground powder, essential oil, decoctions, and capsules

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

Chinese Prickly Ash: dosing

There is no established standardized medicinal dose for Chinese Prickly Ash. As a cooking spice, people use small culinary amounts to taste.If you choose a supplement, extract, or essential oil product, follow the directions on the product label and do not exceed them.

About Losartan

What Is Losartan Used For?

Brand name: Cozaar

Losartan tablets — available as branded Cozaar and several generic products — are used to treat high blood pressure (hypertension) in adults and children 6 years and older. Lowering blood pressure reduces the risk of strokes and heart attacks. Losartan tablets are also used to reduce the risk of stroke in people with high blood pressure who also have left ventricular hypertrophy (an enlarged left side of the heart). Note: evidence suggests this stroke-risk benefit may not apply to Black patients.

Losartan tablets are additionally approved to protect the kidneys in people with type 2 diabetes, high blood pressure, and signs of kidney damage (diabetic nephropathy). Arbli, the oral suspension form, shares these same approved uses.

Most-Reported Side Effects for Losartan Potassium

From FAERS, the FDA’s public side-effect reporting system (89,498 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 6,464 reports
Nausea 5,301 reports
Diarrhea 5,184 reports
Dyspnea 4,689 reports
Dizziness 4,429 reports
