Quality of botanical products starts with the selection of the plant material.

Experience shows that herbal materials purchased from standard wholesale sources may not be suitable for the development of a premium product. The desired indications for a particular product requires an optimal phytochemical quality finetuned to the intended use.

Correspondingly, the development of premium products or the upgrading of standard qualities should start with a phytochemical screening and the identification of stable cultivars or chemotypes ensuring a reproducibility of results.

Eusano organises such screening projects linking the field work and cultivar identification with sophisticated analytical laboratory work and bioguided testing in pharmacological models.
