Christiane's Naturkraft makes elderberry products in Austria, rooted in the herbal recipes Christiane Rauch shared with family and friends from 1968. Today her son Stephan and the Christiane team, advised by scientists and clinicians, develop those recipes in light of current research. The range includes Sirup Klassik, Sirup PRO, Kinder Sirup and Essenz Cuvée 2026, each with added vitamin C and zinc, which contribute to normal immune function. Ingredients are always clearly explained.
