Krachai Plant Information
Also popular as Finger root, Kachai, Chinese keys, and Kunci, Krachai (Boesenbergia rotunda) is a relative of turmeric and ginger. Its rhizomes are used as a spice and give mild ginger and citrus-like flavor.
It grows slowly and reaches up to 2-4 feet in height. This plant looks like an Iris and produces beautiful pale pink blossoms. Unavailable fresh in most parts of the world, it makes a lot of sense to grow it in the garden.
According to research, the plant possesses anti-allergic, antibacterial, anticancer, anti-inflammatory, antioxidant, and antiulcer activities and has wound-healing properties. Its common phytochemical components include alkaloids, essential oils, flavonoids, and phenolics. This plant is rich in boesenbergin, krachaizin, panduratin, and pinostrobin, all of which have been reported to contribute to its remedial properties, including aphrodisiac properties.
