“THE SANSEVIERIA IS AN ECO-FRIENDLY PURIFYING PLANT”
NASA reportedly revealed that Sansevieria has an excellent ability to absorb up to 107 atmospheric pollutants, including carbon monoxide and nitrogen oxides.
As if this were not enough, another study conducted by the Wolverton Environment Service found that Sansevieria absorbs formaldehyde, chloroform, benzene, xylene and trichlorethylene, thus earning a reputation for regenerating air, for the sick building syndrome.
The Sansevieria cylindrica, uses the metabolism process of Crassulacean acid, which absorbs carbon dioxide and releases oxygen at night.
This supposedly makes them suitable bedroom plants. However, since the leaves are potentially poisonous if swallowed, it is generally not recommended for children’s rooms.
In addition to ornamental and decorative plants, they are very healthy, for the air we breathe in our homes.
