Twin brothers and pharmacists Jean and Henri Boiron founded the company Boiron in Lyon, France in 1932. Later, in 1983, the company penetrated the U.S. homeopathic market by obtaining the company John A. Borneman & Sons, Inc. in suburban Philadelphia. At present, Boiron USA is known as a leading homeopathic medicine supplier in America. Leading by example, Boiron is passionate about its commitment to the environment. Even though the preparations of their products have minimal effects on the environment, Boiron prefers to pay their debt to mother Earth by re-supplying wild plants from which their ingredients are sourced. This brand works with expert botanist-harvesters that are knowledgeable in using the land, obtaining the optimum use of it while at the same time using strategies to foresee continuity of supply for the future. All of their products are manufactured in accord with the Homeopathic Pharmacopeia of the United States.
