Please read before use: the information below describes traditional and informational uses — it does not replace advice from a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

The fronds must be thoroughly cooked before consumption; raw use is not documented as safe and should be avoided. As with many ferns, excessive or repeated consumption is not recommended in the absence of sufficient data on long-term safety. Avoid harvesting near polluted or treated areas, as the plant tends to absorb substances from the surrounding soil and water. Consult a healthcare professional before any medicinal use, particularly during pregnancy or breastfeeding.
