Quisqualis indica also known as the Chinese honeysuckle, Rangoon Creeper, and Combretum indicum is a vine with red flower clusters and is found in Asia. It is found in many other parts of the world either as a cultivated ornamental or run wild. Other names for the plant include Quiscual (in Spanish), Niyog-niyogan (in Filipino), Madhu Malti or Madhumalti (in Hindi), Akar Dani (in Malay) and Radha Manoharam (in Telugu). The genus translates into Latin for What is that?.
The Rangoon Creeper is a ligneous vine that can reach from 2.5 meters to up to 8 meters. The leaves are elliptical with an acuminate tip and a rounded base. They grow from 7 to 15 centimeters and their arrangement is opposite. The flowers are fragrant and tubular and their color varies from white to pink to red. The 30 to 35 mm long fruit is ellipsoidal and has five prominent wings. The fruit tastes like almonds when mature. The niyog-niyogan is usually dispersed by water.
The plant is used as an herbal medicine. Decoctions of the root, seed or fruit can be used as antihelmintic to expel parasitic worms or for alleviating diarrhea. Fruit decoction can also be used for gargling. The fruits are also used to combat nephritis. Leaves can be used to relieve pain caused by fever. The roots are used to treat rheumatism.
The seeds of this and related species, Q. fructus and Q. chinensis, contain the chemical quisqualic acid, which is an agonist for the AMPA receptor, a kind of glutamate receptor in the brain. The chemical is linked to excitotoxicity (cell death).
