The rhizomes of Alpinia jianganfeng are used as a traditional Chinese medicine, Jian Gan Feng, to cure rheumatism in Guangdong, China. The rhizomes of some other species of the genus Alpinia such as A. japonica, A. suishaensis and A. nanchuanensis are also used as Jian Gan Feng in Southwest China. However, the identification of the original plants of the crude drugs is difficult. The internal transcribed spacers and the 5.8S coding region of nuclear ribosomal DNA of the four species were sequenced and analyzed. The DNA markers have been determined and they can be used for the molecular identification of these medicinal plants.
假益智的根茎在中国广东被用作传统中药“箭杆风”来治疗风湿病。其他一些山姜属植物的根茎，如日本山姜、水山姜和南川山姜，在中国西南部也被用作“箭杆风”。然而，这些药材原植物的鉴定很困难。对这四个物种的核糖体DNA的内转录间隔区和5.8S编码区进行了测序和分析。已确定了DNA标记，它们可用于这些药用植物的分子鉴定。
