Similasan homeopathic products are formulated using traditional guidelines and produced according to strict Good Manufacturing Practices (GMP) by Similasan AG at the North American headquarters, located just south of Denver, Colorado. Similasan AG in Switzerland was founded by Swiss druggist Armin Spaeni from a line of combination homeopathic remedies that he created for his retail store. After realizing the success that his remedies had in treating his patients’ ailments, Spaeni, along with two friends, founded Similasan AG in Jonen, Switzerland in 1980 to enable them to manufacture larger quantities of remedies for their rapidly growing customer base. Similasan quickly became one of the best selling brands in Swiss drugstores, where it remains as a top seller of over- the- counter remedies. Similasan Corporation was founded in 1987 with the introduction of Dry Eye Relief eye drops, which is hugely popular in Switzerland. Americans immediately realized the benefit of using a gentle, homeopathic eye drop and the Similasan Corporation story began. Since then, Similasan products have found a place in the American family's medicine cabinet by offering safe and effective remedies to relieve ailments of the eyes, ears, nose, nerves, and chest.
