Sorrel and Clopidogrel

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Clopidogrel

Clopidogrel falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Sorrel interacts with.

Theoretically, sorrel might cause additive effects and side effects when used with anticoagulant or antiplatelet drugs.
In vitro, sorrel has been shown to inhibit platelet aggregation. However, this effect has not been reported in humans.
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 gist: Clopidogrel (Plavix) works by keeping your platelets from clumping together, which lowers your risk of clots after a stroke, heart attack, or stent. In lab dish studies, sorrel has shown its own mild ability to slow platelet clumping too. So in theory, pairing them could nudge that effect a little further in the same direction, meaning a slightly higher chance of bruising easily, nosebleeds, or bleeding that's slow to stop.

The honest caveat: this is only based on test-tube work and hasn't actually been seen in people. The small amount of sorrel you'd eat in cooking is very unlikely to matter. If you're thinking about concentrated sorrel supplements, just run it by your pharmacist or doctor first, and never stop your Plavix on your own.

About Sorrel

What is Sorrel?

Sorrel
  • Sinus and respiratory congestion
  • Digestive upset
  • Fever
  • Skin conditions and inflammation
  • Antioxidant support

Sorrel is a tangy, leafy herb used in cooking and traditional medicine, often for congestion, digestion, and inflammation. Solid human evidence for any health benefit is limited, and its high oxalate content means it should be used in moderation, especially by people prone to kidney stones.

About Clopidogrel

What Is Clopidogrel Used For?

Brand name: Plavix

Clopidogrel tablets are used to reduce the risk of heart attack and stroke in people with acute coronary syndrome (ACS) — including unstable angina and non-ST-elevation or ST-elevation heart attacks — and in people with a history of recent heart attack, recent stroke, or established peripheral arterial disease. For ACS, it is typically given alongside aspirin.

It works by preventing platelets (blood cells that trigger clotting) from clumping together, which helps keep arteries open and lowers the chance of a dangerous clot forming.
