The World Health Organization extends its appreciation of the generous support provided by the Government of the Grand Duchy of Luxembourg for the development and publication of these guidelines.
WHO also acknowledges its indebtedness to the more than 240 reviewers, including experts and national authorities, in over 105 countries who provided comments and advice on the draft texts. Preparation of these guidelines benefited, in addition, from technical support received from relevant United Nations agencies, international organizations and nongovernmental organizations.
Special thanks are due to participants of the WHO Consultation on Good Agricultural and Field Collection Practices for Medicinal Plants, held in Geneva, Switzerland in July 2003 to review the draft guidelines (see Annex 6), and to the experts who participated in the WHO Working Group Meeting held in Geneva, Switzerland in October 2003, to review and revise the draft guidelines.
Acknowledgement of their preparation of the original text is also due to: Professor Harry H.S. Fong of the WHO Collaborating Centre for Traditional Medicine, College of Phamacy, University of Illinois at Chicago, Chicago, Illinois, USA; Professor James E. Simon of the New Use Agriculture and Natural Plant Products Program, Cook College, Rutgers University, New Brunswick, New Jersey, USA; and Dr. Jacinto Regalado of the Missouri Botanical Garden, St. Louis, Missouri, USA.
Finally, WHO thanks Health Canada of the Government of Canada, especially the Natural Health Products Directorate, Health Products and Food Branch, which hosted and supported the WHO Informal Meeting on Methodologies for Quality Control of Finished Herbal Products, in Ottawa, Canada in July 2001. It was at this meeting that the idea of developing these guidelines was first discussed and recommended.
