Cubebs and Magnesium Sulfate (prescription drug)

Here is the interaction we found between these two, with the evidence behind it.

Minor

ANTACIDS

Why this applies to Magnesium Sulfate (prescription drug)

Magnesium Sulfate (prescription drug) falls under ANTACIDS — the group Cubebs interacts with.

Theoretically, due to reports that cubebs increases stomach acid, cubebs might decrease the effectiveness of antacids.
Severity Minor 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for cubebs and magnesium sulfate. When magnesium sulfate is used as an antacid or laxative, it works partly by neutralizing stomach acid. The thinking on file is that cubeb berries might nudge your stomach to make more acid, which could slightly work against that acid-soothing effect. So in theory you might get a little less relief from heartburn or sour stomach.

Honestly, this is a very minor, theory-based concern resting on weak anecdotal reports, not solid studies. A sprinkle of cubeb as a spice almost certainly won't matter. Concentrated cubeb extracts or oils are more of a question mark. If you're using magnesium sulfate regularly and want to try cubeb supplements, just run it by your pharmacist or doctor first.

From our pharmacist’s overview on the Magnesium Sulfate (prescription drug) page

“Alcohol tops this list for a reason. Beer and wine both carry major ratings with prescription magnesium sulfate, which itself quiets the nervous system (doctors use it for conditions like eclampsia and severely low magnesium), so drinking on top of a dose can deepen sedation in ways that matter.”

About Cubebs

What is Cubebs?

Cubebs
  • Coughs and bronchitis
  • Indigestion and gas
  • Urinary tract complaints
  • Sore throat
  • Culinary spice

Cubebs are spicy, peppery berries from a vine in the pepper family that have long been used in traditional medicine for coughs, digestion, and urinary problems. Modern human studies are very limited, so its benefits are not well proven. Use it cautiously as a food spice, and talk to your pharmacist or doctor before using concentrated extracts or oils.
