In Thailand, the plant is known as “Kwao Krua Kao”, the 'Kao' meaning white which distinguishes Pueraria mirifica from other plants with tuberous roots also sharing the 'Kwao Krua' designation such as Butea superba, commonly called Kwao Krua Deng (Red) and the 'black' and 'dull grey' Kwao Krua plants. The species was definitively identified as Pueraria mirifica in 1952. Dried and powdered, the tuberous root of Pueraria mirifica has a history of domestic consumption in Thailand in traditional folk medicine as a rejuvenating herb to promote youthfulness in both women and men and is used widely within the now government-regulated practice of traditional Thai medicine.
Boesenbergia rotunda, commonly known as Chinese keys, fingerroot, lesser galangal or Chinese ginger, is a medicinal and culinary herb from China and Southeast Asia. In English, the root has traditionally been called fingerroot, because the shape of the rhizome resembles that of fingers growing out of a center piece.
Kaempferia parviflora, the Thai black ginger, Thai ginseng or krachai dum, is an herbaceous plant in the family Zingiberaceae, native to Thailand. Kaempferia parviflora has been the subject of increased scientific interest in recent years. In a systematic review in 2016, 683 records and 7 studies were analyzed, with a reference that krachai dum significantly increased hand grip strength and enhanced the response to sexual erotic stimuli. An earlier study found that acute dosing did not have an effect on sprint and endurance exercise in humans, but indicated that chronic effects or actions in other populations cannot be excluded.
