Thai Black Ginger (Kaempferia parviflora), also known as Krachai Dum, is a plant native to Thailand that has been used in traditional medicine for centuries. It belongs to the Zingiberaceae family — the same family as ginger and turmeric — and is characterised by its dark purple, almost black rhizomes. The plant has been utilised primarily as a tonic for energy and overall vitality, prepared across various regions of Thailand as a brew for stamina and well-being.
The Active Compounds
The active compounds in Thai Black Ginger are primarily flavonoids, with polymethoxyflavones being particularly notable. These compounds — including 5,7-Dimethoxyflavone, 5,7,4'-Trimethoxyflavone, 6-Methoxyflavone, and 7-Methoxyflavone — are thought to be responsible for many of the plant's effects on health.
