Snake plants can **convert carbon dioxide into oxygen** at night, unlike most plants that do so only during the day. This means they can improve the air quality and oxygen level in your bedroom or living room, especially if you have multiple snake plants.

Snake plants can **absorb harmful toxins** from the air, such as formaldehyde, benzene, xylene, toluene, and trichloroethylene. These toxins can come from paints, varnishes, cleaning products, smoke, and other sources, and can cause health problems such as eye, nose, and throat irritation, headaches, nausea, dizziness, and even cancer.

Toxicity

Snake plants are **toxic** to humans, but only if they are **ingested** in large quantities. Snake plants contain **saponins**, which are natural compounds that help protect the plant from pests and diseases. However, saponins can also cause **nausea, vomiting, diarrhea, numbness, swelling, and skin irritation** in humans who consume or contact the plant's sap. Therefore, you should keep snake plants away from children and pets who may accidentally eat them, and wear gloves when handling them. You should also wash your hands after touching the plant, and seek medical attention if you experience any symptoms of poisoning.
