This beautiful pineapple plant is not only hip and trendy, but it also has a useful effect. The plant is known as an anti-snoring plant. The pineapple plant releases oxygen at night unlike other houseplants which release oxygen during the day. The scent of the plant contains the anti-inflammatory enzyme bromelain, which dilates the airways. The pineapple is a type of bromeliad and mainly grows in tropical rainforests. The plants grow as so-called epiphytes, which means that they grow in trees without taking food from them.
