Warning about using patches for painful joints
I had a painful shoulder. My husband suggested using Tiger Balm patches to ease the pain. On my regular visit to check INR , which had been very stable for ages (2.5 target) to my horror INR had spiked to 4.5. I couldn't think what I had done, eaten, drunk differently until husband reminded me about the patches. I thought " Surely they couldn't have had THAT much effect"! I did some research online. Tiger Balm contained Capsicum and Cinnamon oil. Both Capsicum plants and Cinnamon plants contain a natural anticoagulant. I reported my findings to the anticoagulant nurses who were surprised, as I was, at the dramatic effect. They took note and were most interested. . So just a warning that even external applications of plant based remedies can have an effect on warfarin treatment. So please take care when using any form of natural/ herbal products even externally.
