Dapong-kahoi is a bushy parasitic shrub. Branchlets and leaves beneath are densely covered with a tomentum of long- and short-branched hairs. Leaves are opposite, and shortly petioled, usually roundish-elliptical, 5 to 10 cm long, 2 to 5 cm wide, and smooth above when old. Inflorescence is usually 2- to 5-flowered. Flowers are 1.2 to 2.5 cm long, in axillary, stalkless or short-peduncled fascicles. Calyx tube is obovate or pear-shaped, 2.5 to 3.5 mm long, with the limb entire. Corolla is slender, 7 to 17 mm long, with the tube split, and with 4 lobes. Fruit is clavate, 8 to 10 mm long, 3 to 4 mm thick, and hairy.
– A parasitic on miscellaneous trees in many islands, in open forests only a low altitudes in Palawan.
– Occurs in the Malay Peninsula, Sumatra, Java, Borneo, and India.
Plant decoction used for malaria.

• Vascular Relaxation / Anti-Hypertensive: Study of n-butanol fraction of methanol extract of Loranthus ferrugineus showed it induced vascular relaxation by stimulating muscarinic receptors, activating the endothelium-derived nitric oxide-cGMP-relaxant pathway, promoting prostacyclin release. Results support its traditional use as anti-hypertensive agent.
• Cholinomimetic Effect: Study of a methanol extract of L. ferrugineus in isolated guinea pig ileumshowed a spasmogenic effect probably mediated through a direct action on intestinal muscaric receptors.
• Antihypertensive / Vasocontriction Modulation: Study investigated the mode by which LF methanol extract antagonizes or modulates norepinephrine-induced vasoconstriction in rat aortic rings. Results showed LF ME exerted its vascular effect by reversible noncompetitive antagonism of norepinephrine-induced vasoconstriction, providing a mechanism for its antihypertensive effect.
