Research
Three species of Kaempferia, i.e., K. galanga, K. rotunda, and K. angustifolia, are well studied for their essential oils along with other important phytochemical and medicinal properties. The micropropagation procedures of K. galanga and K. rotunda have been studied by many groups for more than two decades, but  in vitro propagation of Kaempferia angustifolia was the first reported in 2018.
