Blechnum underwoodianum
Blechnum underwoodianum, also known as the Underwood's chain fern, is a species of fern in the family Blechnaceae.
It has been traditionally used for its medicinal properties, particularly in treating respiratory issues such as bronchitis and asthma due to its expectorant and anti-inflammatory properties.
The plant is believed to offer health benefits such as reducing inflammation, relieving coughs, and easing congestion, making it a popular choice for herbal remedies.
Blechnum underwoodianum can be prepared as an herbal tea, infusion, or tincture, although more research is needed to confirm its effectiveness and optimal preparation methods.
