Mother-in-law’s Tongue or Cow’s Tongue: Know Its Benefits and Properties
Mother-in-law’s tongue, also known as Sansevieria trifasciata, snake plant, or sometimes colloquially referred to as cow’s tongue, is a hardy, low-maintenance houseplant that’s more than just an aesthetic addition to your home. Native to West Africa, this striking plant features long, upright leaves with sharp, sword-like edges — hence the playful names.
But beyond its decorative value, mother-in-law’s tongue is packed with powerful health and environmental benefits that make it one of the best plants to keep indoors.

Top Benefits of Mother-in-law’s Tongue
1. Air Purification
One of the most celebrated qualities of the snake plant is its ability to clean indoor air. According to a NASA Clean Air Study, Sansevieria can filter harmful toxins such as:
- Formaldehyde
- Benzene
- Xylene
- Toluene
- Trichloroethylene
This makes it ideal for bedrooms, offices, and spaces with poor ventilation.
2. Oxygen Production at Night
Unlike most plants that release oxygen only during the day, mother-in-law’s tongue continues to produce oxygen at night through a process called CAM (Crassulacean Acid Metabolism). This makes it excellent for improving sleep quality when placed in the bedroom.
3. Low Maintenance and Drought-Tolerant
This plant thrives on neglect. It requires minimal watering, making it perfect for busy people, beginners, or those who often travel. It tolerates low light and irregular watering — just avoid overwatering!
4. Mood and Productivity Booster
Indoor plants like Sansevieria have been shown to reduce stress, improve mood, and increase productivity. Having greenery around can uplift your space and your spirit.
5. Feng Shui and Energy Balancing
In Feng Shui, the upward-growing leaves of the snake plant are believed to bring positive energy and protect against negative vibes. It’s often placed near entrances or in offices to enhance mental clarity and emotional stability.
How to Care for Your Mother-in-law’s Tongue
- Light: It prefers indirect sunlight but tolerates low-light corners.
