Parsley is a natural diuretic, which means that it helps the body get rid of excess fluid. It also flushes out excess salt, a common cause of edema. Parsley also supports your kidneys, which are responsible for flushing urine and toxins out of your body. As long as you maintain a healthy water intake and get enough parsley in your diet, your body can flush out water and toxins more quickly and consistently. If water sits in your body for less time, it has less of a chance to build up in your feet.Another benefit of using parsley as a diuretic is its high potassium content. Chemical diuretics often flush potassium out of your body, leading to significant side effects. When you choose parsley instead, you maintain healthy potassium levels. Brewing your own parsley tea at home is an easy way to get this herb into your diet and minimize swelling. Just follow these easy steps to get started. Aim to drink up to two quarts of parsley tea every day.
