The Schuessler salts mineralize the biological body optimally and allow its healing.
Dr. Schuessler found out that the body lacks minerals before it starts suffering materially. As a consequence of his discovery, he created his original 12 salts (recently expanded to 24 salts). They are potentised by a special process but usually not succussed like the homeopathic remedies. Taken properly, the salts re-mineralize the body optimally and contribute to its recovery.
It needs professional therapists to handle the Schuessler rightly and prevent any damage.
