Zeller since 1864

It all began with a plant - and a vision. Zeller has been dedicated to the power of nature since 1864. Originally founded by Max Zeller as a pharmacy in Romanshorn on Lake Constance, Zeller is now a leading Swiss company for herbal medicines - still family-run and now in its fifth generation.
Zeller stands for true pioneering work in the field of phytotherapy: every product is the result of a combination of traditional medicinal plant know-how, cutting-edge research and uncompromising quality. Around 170 experts from the fields of pharmacy, biology and agronomy work here on herbal solutions that are valued by experts and patients worldwide.
We are convinced that health begins with trust - in nature, in research and in the quality of our products. That's why we control the entire supply chain from seed to cultivation to the finished product.
