Kaempferia spp. have traditionally played a role in treating various ailments and are attracting increasing economic and scientific interest. This review evaluates the traditional use, phytochemical compounds, and biological properties of Kaempferia parviflora, Kaempferia galanga, Kaempferia rotunda, Kaempferia pulchra, and Kaempferia angustifolia. The health benefits associated with consuming Kaempferia spp. and their active components, namely flavonoids and other volatile compounds, include antibacterial, anticancer, antidiabetic, cardiovascular protective, immunoregulatory, neuroprotective, and skin-whitening effects, suggesting the use of Kaempferia spp. as a potential health aid for the aging population. As agricultural production is important to ensure consistent quality of Kaempferia produce, resource management techniques related to species identification, cultivation, storage, and processing were also highlighted. It was suggested that the value-added concept in agricultural production may be limited. Investigations into plant biology and physiology are required to provide a solid theoretical basis for the sustainable production of Kaempferia.
