In so-called rational phytotherapy, medicinal plants are processed into standardised finished products (phytotherapeutics) using scientific methods and then also used in conventional medicine. They are also an important component in many alternative healing methods. In contrast to rational phytotherapy, traditional phytotherapy does not rely on isolated individual extracts, but uses complete extracts obtained from whole plants or parts of plants, usually in the form of teas or infusions.

Herbal medicines are used for the following complaints: Gastrointestinal diseases, diseases of the respiratory tract, diseases of the urogenital tract, cardiovascular complaints, nervous disorders, sleep disorders, gynaecology, diseases of the musculoskeletal system and skin diseases.
