Botany
Climbing bird's-nest fern is a robust ground fern. Rhizomes are shortly creeping, thick, about 8 millimeters in diameter. Leaves are attractive, bright green, elongated, tufted, more or less ruffled at the margins and forking in various segments at the apex.

Distribution
- Recently introduced; not widespread in the Philippines.
- Cultivated as an indoor plant.
- Widespread in the Old World.
- Reported in the Pacific islands, Malesia, tropical Asia, from southern China to India, Madagascar and Africa.

Constituents
- Ethanol extract yielded alkaloids, flavonoids, terpenes, phenols.

Properties
- Vulnerary, antibacterial.

Parts used
Leaves

Uses
Folkloric
- No reported medicinal folkloric use in the Philippines.
- Decoction of plant used for coughing fits.
-
Leaf juice used as purgative or enema.
- Leaf juice also used as diuretic and for healing wounds
.
- Used in traditional medicine of Nicobarese tribes.

Others
- Apong: Leaves are used in the preparation of Apong (a kind of rice beer) in Dhemaji and Lakhimpur district. The Misings offer Apong in different rituals to pacify the spirits.

Studies
Antibacterial:
Ethanol extract of whole plant showed inhibition zones towards various bacterial strains viz. E. coli, Micrococcus lutea, Serratia marcesens, Pseudomonas aeruginosa. (2)
Antimicrobial: Study evaluated the antimicrobial activity of Microsorum punctatum and M. scolopendria against 11 bacterial and 8 fungal strains. Ethanol and aqueous extracts of both plants showed comparable antimicrobial activity. (3)
Cytotoxicity / Glucosidase Inhibitory Activity: Study evaluated the cytotoxic activity of six edible and medicinal ferns. All the fern extracts investigated, which included M. punctatum, all showed cytotoxicity toward K562 cells . Concentration-dependent increase in antiglucosidase activity was observed in all fern extracts, except C. interruptus. The EC50 for antiglucosidase activity ranked in ascending order: C. dentata < P. irregularis < N. acutifolia < C. arida < M. punctatum. The EC50 of M. punctatum was 25-fold higher than that of myricetin. EC50 values of cytotoxic activity was 399.68±48.60 µg/mL while antiglucosidase activity was 1345.73 ±139.44 µg/mL. (5)

Availability
- Wildcrafted.
- Ornamental cultivation.
