    Kaempferia rotunda: Brief Summary
    provided by wikipedia

    Kaempferia rotunda is a plant species in the ginger family. It is native to China (Guangdong, Guangxi, Hainan, Taiwan, Yunnan), India, Nepal, Assam, Bangladesh, Indochina, and widely cultivated elsewhere. It is reportedly naturalized in Java, Malaysia and Costa Rica.

    Kaempferia rotunda (blackhorm, Sanskrit: भूमीचम्पा, in Kannada: nela sampige, Hindi: भूमी चम्पा Malayalam: ചെങ്ങനീർകിഴങ്ങ് / മലങ്കൂവ) is a spicy plant with many medicinal uses in Ayurvedic and allopathic medicinal systems. This plant is also called bhumi champa, Indian crocus, peacock ginger, and round-rooted galangale.

    K. rotunda is found in various parts of India and adjoining regions, but seldom in the wild. The plant is groomed in small herbal nurseries for applications in medicine preparation. As its Sanskrit name bhumi champa (bloom from within earth) implies, the indigo-coloured flower shoots from within the soil. In fact, the flower emerges much in advance of the whitish leafy shoot. The flower and leaf are never seen at the same time.

    The flower contains the toxin benzyl benzoate used to make ointments to treat scabies. It has potential antioxidant effects.[non-primary source needed]
