The leaves contain saponins, flavonoids and polyphenols, while the roots contain saponins, flavonoids and tannins. This plant contains Cyanidin-3-glucoside as the main anthocyanin found in flowers. The leaves exhibited strong free radical scavenging activity and the highest tyrosinase inhibitory activity among 39 tropical plant species.

Light wood, quite dense, fine structure and not too hard. Bluish gray or pseudo purple or purplish brown or greenish. Tough and durable survive in the soil. Commonly used as building materials, boats, cartwheels, tool handles, carving and firewood. Bark is soaked and beaten to obtain fiber and rope for further use as the basis for making nets and bags.

Gadis perindu ( Sphagneticola calendulacea ) is a species of flowering plants, spread using seeds, living near water in an open place, getting lots of sunlight, growing fast in the rainy season and strong in all weather conditions in tropical climates. S. calendulacea is commonly found wild in Indonesia, especially in habitats around irrigation channels and rice fields that live together with grass. Plants grow wild and quickly spread during the rainy season on agricultural lands and farmers consider them weeds. These wild grasses have fiber roots, green woody stems, grow to as high as 0.5 meters, green leaves and yellow flowers. The stem generally spreads sideways and grows on the ground, although some stalks go upwards. The leaves grow along the stalk, green, the upper surface has hair and have wavy contours following the arterial lines. The tip of the leaf is pointed, the sides are jagged and has two wings on the left and right. The bottom surface is light green. Flowers c...
