ABSTRACT
In order to promote the standardization of traditional medicines in Laos， China and Laos jointly formed a census team to conduct resource survey， market survey， species identification and others of medicinal plants in Laos. According to the principles of nationality， tradition， effectiveness and commonness， 160 medicinal materials and 40 prescriptions were selected and collected into Lao Herbal Pharmacopoeia after recommendation， examination of experts and review by the established expert committee. Moreover， quality standards of traditional medicine and scientific and clear translation methods were formulated in line with the national conditions of Laos， and the contents were finally compiled according to the 2010 edition of Chinese Pharmacopoeia. The promulgation and implementation of Lao Herbal Pharmacopoeia is a successful example of cooperation in the field of health care between China and Laos， which is conducive to promoting mutually beneficial cooperation between China and Association of Southeast Asian Nations （ASEAN） countries in the field of traditional medicine， and making traditional medicine play a greater role in the medical and health services of ASEAN countries.
