Parsley leaf powder is dried, ground parsley leaves. People take it to ease bloating and gas. It also acts as a mild diuretic, helping the body flush excess fluid. The powder provides vitamins A, C, and K, and some use it for antioxidant support and to freshen breath.
You can take it with food or water. Capsules are common, or you can stir the loose powder into drinks or meals. Do not take large amounts during pregnancy. Parsley can trigger uterine contractions. If you take blood thinners like warfarin, be cautious because of the high vitamin K content. Avoid large, concentrated doses if you have kidney disease.
