I take aloe vera juice regularly, or did for over a year. I stopped when I was having a problem with stiff muscles in my forearms this last spring. I believe that problem has been solved now by reducing my potassium intake since I am on Lisinopril. I had a mild heart attack during the time I was off aloe vera juice where a piece of plaque broke off a floated down stream until it blocked a small artery. Are these events connected perhaps?
