The patient: A 37-year-old woman in Philadelphia

The symptoms: The patient went to the emergency department after four days of pain, swelling, and bruising on the upper part of her left knee. She reported that these symptoms appeared after she’d used a massage gun on her leg.

What happened next: Doctors took the woman’s medical history, noting that she had been on blood thinners for about six years due to previously having a blood clot in her lung and a stroke caused by a small birth defect in her heart that had allowed a clot to reach her brain. She also reported heavy menstrual bleeding.

Leafy green vegetables are packed with nutrients such as fiber, vitamins, minerals and antioxidants — but the verdant veggies can interfere with some medications, such as warfarin, used to prevent blood clots.

Why do leafy greens interact with these medications?

It comes down to the high vitamin K content in leafy green vegetables, Joan Salge Blake, a nutrition professor and registered dietitian nutritionist at Boston University, told Live Science in an email. Many vegetables — like kale, spinach, collard greens, Swiss chard, cabbage, endive, broccoli and Brussels sprouts — are especially rich in vitamin K, containing more than 100 micrograms per serving.
