General Information


Acrostichum aureum is a member of the Pteridaceae family. The crown is erect and very large. The fronds are pinnate, rigid, coriaceous, glabrous, 0.9–1.8m long, 30cm wide, with a rigid naked strip 30–60cm long. The pinnae oblong-lanceolate, the lower shortly stalked and barren, 15–35cm long and 2.5–5.0cm wide; the upper fertile, almost sessile, one 10–15cm long, 1.5–2.5 cm broad, with a recurved margin all rounded and obtuse, or mucronat at the apex, rounded or shortly cuneate at the base and with the margin entire. The mid-rib conspicuous; veinlets often obtuse, anastomosing freely into small irregular areolae, but without any main veins, or any free veinlets. The fertile pinnae wholly occupied with sori except the mid-rib. [1]

Traditional Used:

In Malaysia,  the powdered or grated rhizomes of A. aureum are used to treat wounds, non-healing ulcers and boils.[2] [6]  In India, the frond is applied over venomous snakebites as an antidote.[3] Others, the fertile fronds and roots are used traditionally for syphilitic ulcers.[6]

In Fiji, A. aureum are used to treat sore throat, chest pains, elephantiasis, constipation,purgative and febrifuge. In Bangladesh, the leaves of  A. aureum are used to cure cloudy urine in women.[2]

Pre-Clinical Data


Antifertility activity
It was first reported in 1985 that the ethanolic and acetone extract of A. aureum showed anti-implantation activity in rats. The water soluble fraction of ethanolic (95%) extract was found to have prevented pregnancy in female rats during administered on day 1–7 postcoitus. The fraction does not have neither oestrogenic nor anti-oestrogenic activities. [4]

Cytotoxic activity
In a screening of Bangladeshi medicinal plants extracts of  A. aureum was proved that to have low toxicity against mouse fibroblasts and selective cytotoxicity against different cancer cell lines.[5]

Adverse Effects in Human:

70.8% of patients with allergic rhinitis developed positive skin reaction when provoked with intracutaneous injection of extracts of spores of A. aureum. Of the 20 non-allergic ENT patients, only 20% gave weakly positive skin test and 15% gave mild reactions to nasal provocation test. The result showed that the spores are potentially allergenic.[7]

Used in Certain Conditions

Pregnancy / Breastfeeding

A study reported that the extract of A. aureum prevented pregnancy in rats. Therefore, pregnant women should be cautious when considering its use during pregnancy. [4]
