Corn Silk and Hydrochlorothiazide, Moexipril

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Corn Silk interacts with whole categories of medication. Hydrochlorothiazide, Moexipril falls into 2 of those categories, so it can interact with Corn Silk in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Hydrochlorothiazide, Moexipril

Hydrochlorothiazide, Moexipril falls under ANTIHYPERTENSIVE DRUGS — the group Corn Silk interacts with.

Taking corn silk extract with antihypertensive drugs might increase the risk of hypotension.
Clinical research in both hypertensive and normotensive adults shows that taking corn silk extract lowers systolic and diastolic blood pressure.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your Uniretic combines two blood pressure lowerers: hydrochlorothiazide (a water pill) and moexipril (an ACE inhibitor). Corn silk has a mild blood-pressure-lowering effect of its own, plus a gentle diuretic action that overlaps with the water-pill side of this combo. So the concern here isn't about your liver breaking down the drug. It's simply that two blood-pressure helpers can add up.

If they stack too much, you might feel dizzy or lightheaded, especially when standing up quickly, or notice tiredness and more frequent urination. To be clear, this is a theoretical interaction based on how each works, not strong proof of harm. Casual amounts likely matter less than concentrated extracts. Before adding corn silk, just check with your pharmacist or doctor.

DIURETIC DRUGS

2 of 2

Hydrochlorothiazide, Moexipril also falls under DIURETIC DRUGS.

Taking corn silk with diuretic drugs might increase the risk of adverse effects such as hyponatremia and hypokalemia.
Clinical research shows that taking corn silk extract increases urine volume and promotes the urinary excretion of sodium and potassium. Some patients may require electrolyte supplementation.
Severity Moderate Likelihood Possible Evidence D

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your Uniretic combines two blood pressure medicines: hydrochlorothiazide (a water pill) and moexipril (an ACE inhibitor). Here's the wrinkle with corn silk. It seems to act like a mild diuretic too, nudging your kidneys to flush out more water, sodium, and potassium in the urine. Stack that on top of a medicine already doing similar work, and the effects can add up.

What might that look like in real life? Possibly lightheadedness, dehydration, or low sodium (think confusion, fatigue, muscle cramps). The potassium picture is trickier, since hydrochlorothiazide lowers it but moexipril tends to raise it. This is a theoretical concern based on how these things work, not strong proof. Still, please loop in your pharmacist or doctor before adding corn silk.

From our pharmacist’s overview on the Hydrochlorothiazide, Moexipril page

“Uniretic pairs hydrochlorothiazide, a water pill, with moexipril, an ACE inhibitor, so it lowers blood pressure two ways at once, and that combination earns real caution with supplements. Of the 248 herbs and supplements with an interaction on file, 16 rate major, and those are the ones to understand first.”

About Corn Silk

What is Corn Silk?

Corn Silk
  • Urinary tract and bladder problems
  • Mild fluid retention (diuretic)
  • Kidney and prostate concerns
  • Bedwetting in children
  • Soothing urinary irritation

Corn silk is a traditional herbal remedy taken as a tea or extract, mostly for urinary and mild fluid-related complaints. High-quality human evidence for these uses is limited, so it should not replace proven treatments. It is generally considered low-risk for short-term use in healthy adults, but talk with your pharmacist or doctor before trying it.
