From that day on, Dr. Niehans replaced transplants or implants with injections for his patients at Clinique La Prairie. These contained fresh cells from organs that were mostly endocrinological, taken initially from young animals, and later from sheep foetuses. He even injected himself. Encouraged by the feelings and observations of his patients, he was convinced that such injections of
new tissues stimulated the healing, recovery or rejuvenation of the corresponding human organ.
Word spread quietly yet swiftly among the elite. Soon, Montreux became a discreet haven for the powerful. Winston Churchill, Konrad Adenauer, and royalty sought Dr. Niehans' revolutionary "youth cures." In 1953 Dr. Niehans was summoned to the Vatican to treat Pope Pius XII. The successful therapy catapulted Clinique La Prairie into global spotlight. The news immediately spread round the world, carrying with it the name of Clinique La Prairie. A reputation that is still alive today.
