Hi, Christinele, I am curious as to how long ago you were diagnosed with ET. To help with your question: According to Google search, foods that reduce platelet aggregation are dark chocolate (yes!), garlic, ginger, onion, purple grape juice, tomato and wine. As I mentioned in my reply to arti4, we each have a choice as to what we put into our bodies. I, too, am at present feeling healthy and happy, without symptoms, so will refrain from the hydroxy, but will monitor my platelets as usual. Wishing you many more good years ahead!
