After two heart attacks, 3 months apart, my husband and I diligently researched for natural helps to keep arteries clear. He has done a great deal but we feel, after much research and use, that daily either juicing with carrots and one quarter greens of some type or using a top quality green powder drink is vital. There is no doubt in our minds that green food which has not been heated to kill enzymes cleans arteries. Of course he has done and does much more. But if we could only do one thing, it would assuredly be to drink green! It has been 8 years now since those two heart attacks and he is currently on no medications and feels great.
