Warfrin - Can I drink Dr Red's rosella punch? I have been told not to take fish oil and some other vitamin suppliments, but was wondering if I could have 25mL once a day of this wonderful antioxidant natural syrup. My wife and children enjoy the benefits of this and the Blueberry punch as well which has been better than anything else for my teenage daughter who is recovering from glandular fever. I generally take 5 -6.5 of Warfrin.
