Does Spathiphyllum (Peace Lily) Have Toxicity?
As an indoor green plant with both ornamental and purification functions, Spathiphyllum has long been favored by gardening enthusiasts. However, discussions about its toxicity and cultivation taboos have never ceased. This article will systematically analyze the plant's characteristics and provide a scientific cultivation guide.
Toxic Components and Risk Prevention of Spathiphyllum
Calcium Oxalate Crystal Poisoning Mechanism
The transparent liquid exuded by the leaves contains calcium oxalate needle crystals, which can cause redness, swelling, and itching when in contact with the skin. Ingesting it can lead to a burning sensation in the mouth and difficulty swallowing. Experimental data shows that adults can experience poisoning symptoms after ingesting 5 grams of stems and leaves.
Three Principles of Safe Contact
① Wear rubber gloves when pruning ② Place it out of reach of children ③ Rinse with water for 15 minutes immediately after contact with the juice. People with special conditions, such as pregnant women and those with allergic constitutions, are advised to maintain a safe distance of more than 1 meter.
Home Care Guide for Spathiphyllum
Space Adaptation Plan
Recommended to be placed in a living room window sill or阳台 corner with sufficient lighting, ensuring 3-4 hours of scattered light daily. A 1.5-meter-tall plant requires a ceramic pot with a diameter of 35cm or more.
Air Purification Efficiency
NASA clean air research shows that a single Spathiphyllum plant can absorb formaldehyde at an efficiency of 1.23μg/h and increase the concentration of negative oxygen ions by 18% at night, making it especially suitable for newly decorated rooms.
Special Home Protection Measures
Households with pets are recommended to use a transparent acrylic protective cover, and hanging cultivation devices for children's rooms. Emergency plans should include reserves of medical activated carbon and physiological saline.
Rationally utilizing the ecological value of Spathiphyllum, through scientific arrangement and standardized operations, it is entirely possible to achieve a dual balance of safety and aesthetics. It is recommended to replace the cultivation substrate every 2 years and regularly rotate the pot to ensure symmetrical growth of the plant.
