General Information

Allantodia aspera is a large, evergreen fern with an erect, robust rhizome that is rather like a trunk[]. The fronds can be up to 4 metres long[].
The leaves are sometimes gathered from the wild for local use as a food.

Known Hazards

Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[].
Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[].
