[Research progress on pharmacological effects and their differences among the flowers, stems and leaves of Lonicera japonica].

It's a common phenomenon that two kinds or more than two kinds of herbs belong to different parts of the same plant. Lonicera Japonica Flos, Lonicera Japonica Caulis and Lonicera Japonica Folium are the typical representative of this phenomenon. They belong to different parts of the Lonicera japonica Thunb. This paper reviewed the research progress on pharmacological effects and their differences among them. It was found that the research mainly concentrated on Lonicera Japonica Flos, and the others were ignored. However, some pharmacological effects in leaves are stronger than that of flowers and stems, such as antibacterial, anti-bird flu and antioxidant activity.Lonicera Japonica Flos is mainly used for the treatment of respiratory tract virus infection while Lonicera Japonica Caulis is mainly used for the treatment of hepatitis virus infection, respectively. Finally, main problems and suggestions on pharmacological effects among them were also discussed.
