The GPT is one of the members of the European Scientific Cooperative on Phytotherapy (ESCOP).

The European Scientific Cooperative on Phytotherapy (ESCOP) was founded in 1989 as the European umbrella organization of many national phytotherapy societies. The ESCOP today has members from both European and non-European countries. The main objectives of the ESCOP are the promotion and development of scientific status and the harmonization of the regulatory status (authorization) of herbal medicinal products within Europe.

First and foremost, the ESCOP is engaged in a committee of members with the elaboration of drug monographs, which are discussed with European experts before publication. The monographs of ESCOP are prepared in the structure of a "Summary of Product Characteristics" (SPC) in accordance with EC Directive 65/65 / EEC. These monographs have a high priority because of the cited sources and are documented in a comprehensible way.

The monographs contain detailed information on the drugs used and their ingredients and detail the results of the available pharmacological, kinetic, toxicological and clinical studies. Based on the published data, information on the application, such as the indications, dosages, side effects, Contraindications and interactions listed.

So far, more than 100 monographs have been produced and published: After a multi-volume loose-leaf collection, 80 monographs in 2003 and 27 new and 8 revised in September 2009 in book form and at the beginning of 2012, a first monograph as "online" version or file (available on the ESCOP website). Many more new monographs and updates of earlier monographs are under revision.
