The objective of this research was studied indigenous knowledge of Zingiberaceae by the Phu Thai ethnic group in Nakhon Phanom province, Thailand. A field survey was performed through observation, participation and interview with local healers and general villagers. The data was analyzed by using Independent-samples t-test, One Way ANOVA, indices of informant consensus factor (ICF), fidelity level (FL%) and use value (UV). The results found that Phu Thai ethnic group continues to use Zingiberaceae for their life, and they got form home garden and forest around the village. A total of 21 species were utilized. They were used as edible about 16 species. Five species was cultural used. And two species was other plant used. Some species used more than one ethnobotanical uses but some use only one ethnobotanical uses. The many parts of plant were used; there were rhizome, leaf, shoot and inflorescence, respectively. The most part used was rhizome. Alpinia galanga is the highest use value or UV (0.41) and follow by lower use value. Kaempferia marginata is the lowest use value (0.04). The Informants’ consensus index factor (ICF) was found to range between 0.93 (Injuries) and 1.00 (each for Blood system disorders, Circulatory system disorder and Pregnancy/Birth/Puerperium disorders). The highest fidelity level (FL%) values were calculated for Zingiber officinale (80.83), showing the important species which most use for medicine in Phu Thai. While, the lowest fidelity level values were calculated for K. rotunda (10.67) which is less used for medicine Phu Thai. Older informants had highly significant knowledge on plant uses than the younger. Knowledge on plant uses was significant higher in the women. Ethnobotany of Zingiberaceae used by the Phu Thai ethnic group effects the interaction of their life style, beliefs, and rituals. Unfortunately, such knowledge is being lost, thus, these should be promoted and conserved.
