*Petroselinum crispum is a favorite of mine when supporting a body holding onto excess liquids such as in edema. If I needed to use it I would use it orally AND make a poultice and put it on the closest location to the problem. I would also pair it with Kidney support to encourage the body to flush out the accumulated moisture in the way that it was designed to do. Kidneys may want long term support in these situations. Parsley leaf also lend itself towards bladder and kidney support.
