Increasing role of the WHO monographs on selected medicinal plants
Over the past two decades, there has been a tremendous increase in the use of herbal medicine; however, there is still a significant lack of research data in this field. Therefore since 1999, WHO has published three volumes of the WHO monographs on selected medicinal plants: volume 1 includes 28 monographs; volume 2 contains an additional 30 monographs; and volume 3 provides 31 monographs. Including the 28 new monographs published in this volume, a total of 118 monographs in four volumes are now available on the WHO web site (http://www.who.int/medicinedocs/ en/m/abstract/Js14213e/).
