Research is a kind of investment. If its result can be utilized, it will be worth the investment. The objective of this study is to develop the output from the project “Good Agricultural Practice (GAP) for Panjakhan[Gynostemma pentaphyllum (Thunb.) Makino]” which was a cooperative project between the Department for Development of Thai Traditional and Alternative Medicine, Ministry of Public Health and several public organizations. The Panjakhan which were cultivated in four local areas i.e. Chiangrai Horticulture Center, Department of Agriculture; Baan Luang Forest, Mae Kum Me Forest and Mae Jam Forest, The Forest Industry Organization, were further studied. This time the development of Panjakhan was carried out in collaboration with three private organizations i.e. Leo Herbs Co., Ltd., Khaokho Talaypu Co., Ltd. and Green Khelang Co., Ltd. This study makes the private sectors understand the research and development process for herbal products, ensure the quality of crude drug and know how to develop Panjakhan into various health products. Commercialization of the product can be pursued. The collaboration between public and private organizations on this project enable each side to understand each other and enable the government organization to serve the need of the private sector better. Furthermore, this collaboration can be served as a model for future collaboration in research and development in other areas of herb.
