Health Benefits of Fern

The Samambaia is a favorite decoration plant in the 1970s and 80s that came back with everything. The scientific name of the fern is Phlebodium decumanum. Its ancestors are between 359 and 299 million years old and are from the Carboniferous Period, belonging to the Paelozoic era.

The name comes from the Tupi-Guarani sama-mbae, which means “the one who twists in a spiral”. A common plant in tropical areas of Latin America, the fern grows in shaded areas of forests, rocks and by the sea. The plant is formed by the following elements:

  • Rhizoids: thin and resistant, the rhizoids are at the base of the leaves;

The fern is a pterodophyte, the same group as the fern, mackerel and tree fern. The word pterodophyta comes from the Greek pteridon, “fetus” and “plant”. The name refers to the position of the baby-like buds in the womb. Proliferation is not by seeds but by seedlings, especially deer antler, you can use seedlings. Transplanting should be done when long leaves appear. Take them out with the help of a penknife, put them in the vase and fix this seedling with a piece of wire.

Many species of ferns no longer exist. There are 9 main species that cover between 9 and 15 thousand types. The shapes of the leaves look like fish bones, horns and lace. Most of them come from tropical areas and are used in decoration.
