摘要：
An extract for treating hepatitis extracted from the roots or stems of Urticaceae by organic solvents is disclosed. The Urticaceae used in the present invention has a unique sequence of internal transcribed spacer of rDNA, which is at least 70% sequence similarity with that of Boehmeria frutescens, Boehmeria zollingeriana, Urlica thunbergiana, Pilea spp., Boehmeria nivea or Boehmeria densiflora. The extract of the present invention can inhibit the DNA replication of both the wild type hepatitis B virus and the lamivudine-resistant hepatitis B virus.
