Wallflower and Methylprednisolone

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

Moderate

CORTICOSTEROIDS

Why this applies to Methylprednisolone

Methylprednisolone falls under CORTICOSTEROIDS — the group Wallflower interacts with.

Use of corticosteroids may cause electrolyte depletion and increase risk of cardiac glycoside toxicity.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing Wallflower and methylprednisolone. Wallflower naturally contains cardiac glycosides, the same type of heart-active compounds found in digitalis. Methylprednisolone, a corticosteroid, can lower your potassium levels over time, especially with higher doses or longer use. When potassium dips low, the heart becomes more sensitive to those glycoside compounds, which raises the risk of toxicity. That can show up as an irregular or slow heartbeat, nausea, vomiting, or feeling dizzy and faint.

I'll be honest, this is a theoretical caution based on how these substances behave, not on solid human studies. Still, Wallflower isn't safe to take internally on its own. Please check with your doctor or pharmacist before combining the two.

About Wallflower

What is Wallflower?

  • Heart-related folk tonic
  • Nervous tension
  • Joint and muscle aches (topical)
  • Menstrual complaints
  • As an ornamental and fragrance plant

Wallflower (Erysimum cheiri) is a fragrant garden plant with a long history in traditional medicine, but there is very little modern human research to support any health use. It contains cardiac glycoside-type compounds that can be toxic, so it should not be taken internally without professional guidance, and it should be avoided during pregnancy and breastfeeding.
