This invention refers to the preparation for elimination of neuropathies in diabetes. The preparation contains a combination of minerals and plant extracts. By its ionic exchange, the invention reduces considerably the process of apoptosis of nerve-cells, eliminates the process of activation of the immunologic system, and stops the immunologic reaction of auto-destruction of nerve-cells. Depositing of immunoglobulin on axons is absent, and neuropathic pain disappears. Furthermore, the preparation reduces the activity of free radicals, improves the regulation of glycemia and improves the recovery of axons which are already damaged.
