In order to explore the correlation between the medicinal properties，efficacy and application in the same genetic relationship，explain the scientific connotation of the medicinal properties and effects of traditional Chinese medicines(TCM)，promote the academic development of the theory of traditional Chinese medicines，and provide reference for the research and development of the traditional Chinese medicines of a same genus. In this paper, a literature study of ancient and modern works of Chinese herbal medicine was conducted to investigate the correlation between the properties, meridians tropism, efficacy and application of Alpinia officinarum， A. katsumadai， Galangae Fructus and Alpinae Oxyphyllae Fructus, four kinds of Alpinia Chinese medicines．The results showed that the similar properties of these four kinds of Alpinia Chinese medicines included that they were acrid, warm,and mainly getting into the spleen and stomach channels; the similar efficacies included that dispelling cold，relieving pain，warming stomach，anti-nausea，anti-diarrheal，reinforcing spleen to promote digestion and other effects; in application aspects, the similarities were that they were all mainly used in treatment of catching cold or spleen deficiency induced by abdominal pain，vomiting，diarrhea,diet indigestion, etc. indicating that phylogenetic relationship was closely related with the herbal properties, efficacy and application. It is an effective way to explore，collate and research traditional Chinese medicine by using plant phylogenetic relationships in exploring the internal relations and laws of TCM theories，material bases, pharmacological effects and clinical applications, also with a strong maneuverability to explain their scientific connotation.
