The Lotus is revered as India’s most sacred plant. Like the rose in the west, it is a symbol of love and compassion. As a medicinal herb, it has been used in the Orient for over 1,500 years.
Lotus is a perennial, aquatic herb with creeping rootstocks. Leaves are raised above the water, large, rounded, peltate, and 50 to 90 centimeters wide. Flowers are attractive, pink, red, or white, and 15 to 25 centimeters in diameter, standing out of the water. Flower has about 20 pink petals, 7 to 15 centimetersin length. Center of the flower is a large structure shaped like an inverted cone, on top of which are located ovules which later become seeds. Around the inverted cone are numerous yellow stamens. Mature fruit is formed by the enlargement of the spongy, cone-shaped structure in the center of the flower. Rich carpel (fruit and seed in one) is about 13 millimeters long, with a black, bony and smooth pericarp.
– Abundant in marshes and shallow lakes, from northern Luzon to Mindanao.
– Cultivated as pond ornamentals.
– Probably prehistoric introduction to the Philippines.
– Native of Asia.

– Dried seeds contain nelumbine, protein 15.9%, carbohydrates 70%, ash 3.9%, vitamin C2 and CuO 0.59%.
– Rhizomes contain starch 9.7%, ash 1.1%, vitamin C1, asparagin 2%, protein 1.7%, and fat 0.1%.
– Study of stamen extract isolated kaempferol, kaempferol 3-O-D-glucopyranose, sitosterol 3-O-D-glucopyranoside and 2 flavanoids.
– A methanol extract of leaves yielded five norsesquiterpenes, four flavonoids, two triterpenes and one alkaloid: (E)-3-hydroxymegastigm-7-en-9-one, (3S,5R,6S,7E)- megastigma-7-ene-3,5,6,9-tetrol, dendranthemoside B, icariside B2, sedumoside F1, luteolin, quercetin 3-O-β-D-glucuronide, quercetin 3-O-β-D-glucoside, isorhamnetin 3-O-rutinoside, alphitolic acid, maslinic acid, and N-methylasimilobine.

– Used as astringent, cardiotonic, immunomodulator, antiviral, antitumor.
– Seeds are demulcent and nutritive.
– Filaments and flowers are cooling, sedative, astringent, bitter, refrigerant, and expectorant.
– Roots are mucilaginous, demulcent, and emmenagogue; considered by some as aphrodisiac.
