The term 'swelling plant' is a reference to EDEMA, which is a medical condition characterized by an abnormal accumulation of fluid in the body's tissues. EDEMA is caused by a variety of factors, including poor circulation, kidney or liver disease, and certain medications. It can cause swelling in the hands, feet, ankles, and other parts of the body. Treatment for EDEMA typically involves lifestyle changes, such as reducing salt intake and increasing exercise, as well as medications to reduce fluid retention.
