Seed to Patient
We manufacture phyto-pharmaceuticals that meet the highest standards of modern medicine.
We use state-of-the-art scientific methods to develop phyto-pharmaceuticals with efficacy, safety and tolerability.
We continuously improve and broaden our research and development competence and thereby fully control the value and supply chain from the seed to finished product.
Our commitment starts with the screening of plant varieties and selection of elite plant – this stage is crucial for the further development process of the extract and the quality of finished product. Ensuring that all processes are according to GACP and sourcing the highest quality ingredients allow us to develop a portfolio of premium phyto-pharmaceuticals based on unique herbal extracts.
Medicines derived from plants have been known to humanity for thousands of years and are common in every culture. Until not very long ago, the use of medicinal plants as pharmaceuticals (phyto-therapy) was often the only way to alleviate complaints and cure diseases since synthetic drugs are only available since the beginning of the 20th century.
Today, drugs from the evidence-based rational phyto-therapy are widely used as part of modern pharmacotherapy. Zeller phyto-pharmaceuticals have proven efﬁcacy, tolerability and safety in numerous clinical trials. In contrast to this, there are still many herbal preparations available which have no or extremely limited clinical support. For these products, long tradition is the only proof of efﬁcacy.
The treatment with rational phyto-pharmaceuticals can be clearly differentiated from the alternative and complementary treatment methods such as homoeopathy and spagyric medicine, aromatherapy or ayurveda. The therapeutic efﬁciency of many alternative medical treatments is disputed from a pharmacological point of view and the subject of many scientiﬁc discussions.
We follow strict processes to control each stage of production. This carefully considered approach allows for batch-to-batch consistency, which means that the specific medicine tested in clinical trials is the same medicine used in finished products.
The commitment, experience and creativity of our employees are the source of our success. Driven by clinical evidence and applying a quality-first approach to the development of our medicines, millions of people in Switzerland and around the world enjoy the health benefits of Zeller products.
