Welcome to the Bodhi Group! It is nice to meet you here. I have spoken with several people who have had great success using FrequenSea to cure diabetes. They didn't have ulcers yet, but it would work the same way, by improving circulation. One friend in Seattle has been able to go off of almost all of her medications, and has good blood sugar control now. Another friend convinced his father to try it. His diabetes was so bad that he was having a lot of difficulty walking. A week later he was repairing the roof himself.
