Botany
Pagong-pagoñgan is a climbing epiphyte
with slender rhizomes covered with peltate scales, creeping on
trunks and branches. Fronds are of two kinds: sterile and fertile.
Sterile fronds vary from elliptic to round. 1 to 5 cm long, 1
to 2 cm wide, with a rounded apex and a cuneate base. Fertile
variety is narrower, 3 to 5 cm long, 3 to 10 mm wide, on stipes
up to 2 cm long. Sori are arranged in a broad and submarginal
line, not rarely filling the whole surface of the fertile frond.

Uses
Folkloric
• Ground leaves are used
as styptic for coagulating blood and arresting cappilary hemorrhages.
• Also used for eczema, for conditions referred to as 'agihap.'
• Leaves also applied to " bukol" areas, ie, small subcutaneous
lumps and nodes.
• In Malaysia, used for treatment of superficial bacterial infections, cough, gonorrhea.
Studies
• Antibacterial: Study was done on the antibacterial activity of water, ethanol and chloroform extracts of Dp against E coli, S pneumoniae and S aureus. Antibacterial activity against gram-positive bacteria was detected only in the water extract.
• Antifungal: Study showed the chloroform and ethanol extract of Dp possessed mild activity against Trichophyton spp. The water extract was devoid of antifungal activity. The antifungal activity was less potent than griseofulvin, fluconazole and itraconazole. Future studies may produce a potential for the treatment of Athlete's foot.
