Swiss production

More than 100 species of aromatic and medicinal plants are grown in Switzerland for a variety of different applications. They are marketed as aromatic and medicinal plants per se, as well as for preparing herbal remedies, herbal teas, sweets, cosmetic products and various wellness products. The most widely grown aromatic and medicinal plants in Switzerland are mint, sage, thyme and lemon balm.

As domestic production does not cover the total market volume of aromatic and medicinal plants, a large proportion is imported.

Swiss production is generally characterised by the following points:

  • contract-based
  • compliant with organic farming principles
  • grown in mountain areas
  • grown on small family farms grouped into regional cooperatives

Research

Agroscope’s current research in this field focusses on:

Varietal aspects

  • domestication
  • variety selection
  • comparison of provenance (seed production test)

Cultivation aspects

  • propagation methods
  • optimal planting and sowing dates
  • optimal fertilisation with natural nutrients
  • tillage
  • management of water demand
  • protection from pests and diseases
  • optimal harvesting times and techniques
  • drying and conditioning

Priorities

At the interface between producers and buyers, Agroscope plays a pivotal role in aligning the expectations of the sector as a whole and safeguarding Swiss production of aromatic and medicinal plants in terms of quantity, quality and costs.

Focus on quality

Among other things, the research is concerned with determining the best time for harvesting, interactions between plants and the environment and drying conditions, with the aim of producing plants containing high-quality aromatic compounds and secondary metabolites.

Varietal innovation

Agroscope’s work also aims to breed productive varieties of aromatic and medicinal plants which are adapted to Swiss climate conditions and tolerant of pathogens.

Agroscope is also involved in the domestication of new botanical species, mainly alpines, to address the needs of the sector as they seek to develop new products.

Respect for the environment

Cultivation methods are studied and developed with the focus on durability and respect for the environment, with particular emphasis on organic farming principles. This involves limiting the use of inputs, optimising the management of water and developing integrated control strategies.
