Trapa natans (water chestnut), commonly known as singhara in India, belonging to family Trapaceae, is a free-floating plant which grows in shallow water fields, ponds or swampy land. The water chestnut is native to Europe, Asia and Africa where it is well kept in check by native insect parasites. It favours nutrient-rich water with a pH range of 6.7 to 8.2 and an alkalinity of 12 to 128 mg/l of calcium carbonate. The kernels are delicious to eat and contain carbohydrates, proteins and essential minerals and are reported to be used in many ayurvedic preparations as diuretic, aphrodisiac, nutrient, appetizer, astringent, coolant, antidiarrhoeal & tonic. They are also useful in lumbago, sore throat, bilious affections, bronchitis, fatigues & inflammation. The fruits are a good source of nutrition having 16% starch and 2% protein. Stem is used in eye disorders in the form of juice. The plant Trapa natans has also been evaluated for various activities such as analgesic, anti-inflammatory, anti-diabetic and anti-microbial. The literature reveals the use of kernels as diuretic, aphrodisiac, nutrient, appetizer, astringent, coolant, antidiarrhoeal & tonic, fruits as good source of nutrition having 16% starch and 2% protein, plant as analgesic, anti-inflammatory, anti-diabetic and anti-microbial and stem in form of juice in eye disorders.
