Meadowsweet and Aspirin, Aluminum Hydroxide, Codeine Phosphate, Magnesium Hydroxide

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

Moderate

ASPIRIN

Theoretically, meadowsweet might have an additive effect with other salicylate-containing drugs, such as aspirin.
Meadowsweet contains salicin, a plant salicylate; however, salicin doesn't seem to have the antiplatelet effects of aspirin.
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 simple version. Your combination product already contains aspirin, and meadowsweet brings its own natural aspirin-like compounds (salicylates). On paper, stacking the two could add a little more total salicylate to your system. That's why it's flagged, but keep in mind this is a theoretical concern based on how the chemistry works, not something proven in solid human studies. The salicylate in meadowsweet (salicin) is also pretty mild and doesn't seem to thin the blood the way aspirin does.

If you ever did get too much salicylate, classic signs are ringing in the ears, stomach upset, or heartburn. Since you're aspirin-sensitive folks should be careful, it's worth a quick chat with your pharmacist before pairing these. Please don't change anything on your own.

About Meadowsweet

What is Meadowsweet?

Meadowsweet
  • Heartburn and indigestion
  • Cold and flu symptoms
  • Mild aches and pains
  • Fever
  • Joint discomfort

Meadowsweet is a traditional European herb that contains natural salicylates (aspirin-like compounds) and is used mainly for digestive upset, colds, and minor aches. High-quality human studies are lacking, so its benefits are not well proven, and people sensitive to aspirin should be cautious. Talk with your pharmacist or doctor before using it.
