The Clinical-Therapeutic Institute opened in Arlesheim in 1921 under the direction of Maria Ita Wegman. Born in 1876 in Karawang, West Java, she was a physician of Dutch citizenship who integrated anthroposophical principles into medical practice. Her career spanned the development of specialized therapies and the establishment of international medical institutions during the early twentieth century.
Medical Education and Training
Wegman moved to Europe around the turn of the century, where she studied massage and therapeutic gymnastics. She enrolled at the University of Zurich, completing her medical degree in 1911 with a specialization in women's medicine. Following her graduation, she joined an established practice before opening her own independent surgery in 1917.

In collaboration with Rudolf Steiner, Wegman expanded the scope of therapeutic practice by incorporating anthroposophical concepts. In 1917, she initiated a cancer treatment program utilizing mistletoe extract, a remedy initially named Iscar and later known as Iscador. While the treatment remains in use in Germany and other countries, it is classified as a complementary practice and lacks empirical evidence for curative outcomes.
Institutional Expansion
The Clinical-Therapeutic Institute in Arlesheim grew significantly after its founding in 1921. Wegman expanded her reach in 1922 by establishing Haus Sonnenhof, a facility dedicated to the care of mentally disabled children. Simultaneously, she helped co-found the pharmaceutical firm Weleda to produce health-care products. She also directed the Medical Section at the Goetheanum in Dornach, Switzerland, and launched the medical journal Natura.
Administrative Conflict and Final Years
Wegman served on the Executive Council of the Anthroposophical Society until 1936. Internal disagreements led to her departure from the council and the subsequent withdrawal of her society membership. Despite these administrative challenges, she continued to travel through England and the Netherlands to promote her medical work. She died in Arlesheim in 1943 at the age of 67.
