From seed to patient

Max Zeller Söhne AG is one of the few companies that monitor the entire value creation process from the cultivation of the plants all the way through to the finished product.

Every year we invest around 15 per cent of our profits in research, development and quality control measures. This is vital for ensuring the quality, effectiveness and safety of our products, as well as for the development of new medications.

The selection process

Where it all begins
Medicinal plants form the basis of all our herbal medications.

Selection and analysis
Selecting the best plants is a time-consuming process, as it involves analysing the active ingredient profiles of numerous different varieties.

More information about how we select our medicinal plants is available on the website of our subsidiary Vitaplant AG (www.vitaplant.ch).

Cultivation of medicinal plants

Good Agricultural Practice
After the patenting process, large-scale cultivation of the plants begins in adherence with the Good Agricultural Practice guidelines.

Sustainable farming
The cultivation of our raw materials is subject to strict quality standards. We monitor every aspect that can have an impact on quality, such as the seeds and fertilisation methods, as well as the harvesting time and technique. We avoid using synthetic pesticides wherever possible.

Our seamless documentation means that our raw plant materials can be traced all the way back to the field.

Research and clinical trials

Preclinical research
Before clinical trials involving test subjects can take place, the effectiveness and harmlessness of the extracts are tested in a laboratory.

Effectiveness and safety
During the clinical trials, the effectiveness and safety of the medicines is compared with that of placebos, as well as other standard treatments.

Publications
The results of these trials are regularly published in internationally recognised and independent (peer-reviewed) journals.
