The roots of monstera plants have been used to make a remedy for snakebite in Martinique, and parts of the plant have also been used as a topical treatment for arthritis.
Don’t try to replicate any of these treatments on your own, however. All parts of monstera plants contain insoluble calcium oxalate crystals, which cause extreme irritation to the soft tissues inside and outside the body. Handling them without gloves results in irritated and swollen skin, and ingesting them will cause severe gastrointestinal upset.
