Dr. Schuessler
German Doctor Samuel Hahnemann (1755-1843) is considered the father of Homeopathy.
Dr. Heinrich Schuessler, (1821-1898) from Oldenburg, Germany, doctor in homeopathy had a special interest in mineral salts. During his research he found 12 salts to be the basic inorganic constituents of cells, and any imbalance in their proportions could lead to physiologic disturbance and disease.
Dr. Schuessler was very successful with his new therapy, the "biochemic method". Until his death, he treated all of his patients only with cell salts.
