Homeopathic practice had been established on the East Coast of the United States some 20 years before it arrived in California. In the 1880/81 edition of the Catalogue of all Physicians and Surgeons... of the State of California, (San Francisco, Geo. Spaulding, 1880-81), the section titled "Homoeopathic Physicians" lists 146 physicians. Under the law of 1876 each medical society created a Board of Examiners to determine the competency of its members. Homeopaths were approved to practice in California by the Board of Examiners of the California State Medical Society of Homoepathic Practitioners. By 1889 the total number of registered homeopathic physicians reached 423 (61 of whom practiced in San Francisco), and by 1899, 774.
