When you take Danshen, a traditional Chinese herb used for heart health and circulation. Also known as Salvia miltiorrhiza, it’s often chosen by people looking for natural support for blood flow and heart function. But here’s the catch: Danshen doesn’t play nice with some common medicines. If you’re on blood thinners like warfarin, or drugs for high blood pressure, diabetes, or heart rhythm issues, Danshen could make them stronger—or weaker—than they should be. That’s not a small risk. It’s the kind of thing that lands people in the ER.
People take Danshen for its reputation in lowering blood pressure and improving circulation, but they rarely ask what it’s doing to their other pills. The herb contains compounds that interfere with liver enzymes responsible for breaking down medications. That means drugs like warfarin, a common anticoagulant used to prevent clots can build up in your system, raising your risk of bleeding. On the flip side, it might make statins, cholesterol-lowering drugs like simvastatin or atorvastatin less effective, leaving your arteries more vulnerable. And if you’re using insulin or oral diabetes meds to control blood sugar, Danshen might drop your glucose too far—especially if you’re already prone to low blood sugar.
You won’t find these risks on the bottle. Herbal supplements aren’t held to the same standards as prescription drugs, so you’re left guessing. That’s why so many people end up with unexpected side effects after combining Danshen with their regular meds. The truth? You don’t need to stop using it entirely—but you do need to talk to your doctor first. Bring a list of everything you take, including supplements. Ask: "Could Danshen change how my other drugs work?" It’s a simple question, but it could save your life.
Below, you’ll find real-world cases and expert insights on how Danshen interacts with common medications—what to watch for, what to avoid, and how to stay safe without giving up natural options entirely.
Danshen may seem like a natural way to support heart health, but mixing it with blood thinners like warfarin or Eliquis can cause dangerous bleeding. Learn why this herbal supplement is risky and what to do if you're taking it.
