I've been doing a lot of reading about coumadin and a lot of the healthy things I do for myself like drink green tea; take CoQ10; Fish Oils; Omega 3s; cranberry and eating dark green leafy veggies are actually not recommended for consumation if you are on coumadin.
Here goes.
So, don't take coumadin. If you feel safer, then maybe look into getting off that shitt once you are through this situation.
