Mother-in-Law’s Tongue or Cow’s Tongue: Know Its Benefits and Properties

By Vitia

Commonly known as Mother-in-Law’s Tongue or Snake Plant, Sansevieria trifasciata is a hardy, striking houseplant admired for more than just its unique appearance. Some people also refer to it as Cow’s Tongue due to the sharp, upright nature of its leaves. But beyond its aesthetic value, this plant has a range of impressive benefits — from purifying air to supporting overall wellness in your indoor space.

1. Natural Air Purifier

One of the most well-known properties of Mother-in-Law’s Tongue is its air-cleansing ability. NASA studies have shown that the plant can absorb toxins like:

  • Formaldehyde
  • Benzene
  • Xylene
  • Trichloroethylene

Unlike most plants, it also converts CO₂ into oxygen at night, making it ideal for bedrooms to improve air quality while you sleep.

2. Easy to Care For

If you’re not blessed with a green thumb, this plant is your best friend. It thrives in low light, survives infrequent watering, and adapts well to varied indoor environments. Its resilience makes it one of the easiest houseplants to maintain — perfect for busy households or beginners.

3. Symbol of Positive Energy and Protection

In many cultures, especially in Feng Shui and traditional African beliefs, Mother-in-Law’s Tongue is considered a protector plant. It’s thought to:

  • Wards off negative energy
  • Bring prosperity and luck
  • Strengthen emotional stability in the home

Placing it near the entrance or in living rooms is believed to create a protective energy barrier.

4. Potential Medicinal Properties (With Caution)

While this plant isn’t typically consumed, in some traditional medicine practices it’s used externally to soothe skin inflammation or wounds. However, it’s toxic when ingested, especially to pets and small children. Always keep it out of reach and consult a healthcare professional before any use.

5. Enhances Indoor Aesthetics

With its tall, upright leaves and bold patterns, Mother-in-Law’s Tongue adds a modern, elegant touch to any indoor space. It blends well with minimalist, boho, or contemporary décor and creates a fresh, green corner with little effort.


Whether you call it Mother-in-Law’s Tongue or Cow’s Tongue, this plant is more than a decorative piece — it’s a functional, symbolic, and air-purifying powerhouse.
