Red (Neck) (Goodlettsville, Tn.) on 03/23/2018: For Edema, I have done many things but Serrapeptase seems to work the best as Edema's cause would be an enlarging heart caused by the interior wall of the heart thickening and stiffening due to "critter" infestations causing scar tissue to form in that part of the heart.
Also inositol and D-Ribose helps lots. Also, if the O2 levels in the blood are low the heart will attempt to compensate by pumping harder and frequently the lungs are the source of the problem as the crud we breathe plugs up and scars the lungs thus reducing the O2 uptake by the blood.
For toxic moments in life, Burdock Root or Milk Thistle helps the liver clean out the "remains of the dead critters" and clean water is very helpful too.
