Claude and Marie-France now work with German naturopath Wighard Strehlow, the successor of German physician Gottfried Hertzka (1913–1997) — a Nazi resistance fighter who rediscovered St. Hildegard when he was in a concentration camp. Strehlow has devoted his life to transmitting Hildegard’s medieval remedies “in concrete, accessible terms” for today’s generations.
“The more science progresses, the more we understand what St. Hildegard meant,” the Delpechs said in an email. “One of the latest examples is violet balm. St. Hildegard recommends it against cysts and mastitis, saying that ‘if it’s cancer, it will die when it has tasted it.’ It’s a bold thing to say in the 12th century… but last year, an Australian study demonstrated that the leaves and flowers of violets are powerful anti-cancer agents.”
To date, only 400 of Hildegard’s 2,000 remedies have been tested.

Over the years, the Delpechs have collaborated with a group of French doctors and launched a summer university program. They combine dietary advice with a spiritual component, preached by theologian Father Pierre Dumoulin. At the request of the Catholic community Foyers de Charité, they also began offering a spiritual retreat with a fast based on spelt. The initiative has met with enormous success, with growing demand from people seeking deeper spiritual and physical well-being.
A message of personal unity
Today, the couple’s business, based in Coux and Bigaroque in the Périgord, employs about 15 people. They sell spelt-based products, plants and spices, essential oils, gemstones, flavored wines, cosmetics, and various books.
The community of disabled brothers of Notre Dame d’Espérance participates in the preparation of the elixirs.

Claude and Marie France remain as volunteers in their business, which they see as a mission of evangelization.
“We’re very concerned that the spiritual side should not be neglected, but rather brought to the fore,” they said. For them, St. Hildegard is “a way of getting people to go to retreats they would never otherwise have gone to, because not everyone is interested in the Lord, but everyone is interested in their health.”

During these retreats, people regain their shape and vigor, but something also happens “at the heart level,” they noted. “When you eat less, less fatty, less heavy things, something also happens on the mental level, and there’s a facilitation on the spiritual level, too.”
St. Hildegard’s work, argued the Delpechs, is “a message of personal unification. As the saint wrote: ‘When soul and body function in perfect harmony, they receive the supreme reward of health and joy.’ Joy is essential to Hildegarde.”
The Delpechs said their aim is to restore St. Hildegard to her rightful place within the Catholic Church.

“St. Hildegard was initially known in the New Age [movement], presented as a healer, as the first of the phytotherapists, as a magician, a miracle worker,” the couple said in an email. “But above all, she’s a Catholic saint with a unique charisma. The universe remains a great mystery, and for her, the Lord lifted the curtain. She was able to see the hidden subtleties of creation in the mineral, vegetable, and animal worlds. What a gift!”
Benedict XVI proclaimed St. Hildegard of Bingen a doctor of the Church not only for her spiritual work but also for “her holy medicine.”
