The Bodos of Assam use it as a flavoring herb and add it to soups,
chicken, curries, and also as a side dish with chillies and native soda
ash water called
kharwi. Ngai Camphor is found in dry fields,
thickets, grasslands, mountain slopes, riverbanks; below 1200 m,
throughout the Indian subcontinent, including lower Himalayas, and SE
Asia. Flowering: November-December.
Medicinal uses: In Philippines, Ngai Camphor
is primarily used as a diuretic (or "water pill") and to treat symptoms
of the common cold. As a diuretic, it is a herb used to treat urinary
tract or kidney stones and urinary tract infections, and thus reduces
high blood pressure.
