1. It’s the Best Air Purifying Plant

Aloe vera’s effectiveness as an air-purifying plant can be attributed to its unique ability to absorb and break down indoor air pollutants. This includes VOCs such as formaldehyde and benzene, which are commonly released by household products.

The leaves contain specialized cells called “parenchyma cells” that have a high surface area, allowing them to absorb these chemicals efficiently. Once absorbed, the plant converts them into harmless compounds, thus improving indoor air quality.

2. Soil Conditioner

Aloe vera can improve soil structure as it contains compounds called “polysaccharides” that help increase soil porosity and water-holding capacity.

You can mix 1 part aloe vera gel in 10 parts soil, try it in one of your container plants, and see the results.

3. Aloe Vera as Rooting Hormone

Aloe vera can be a great natural rooting hormone,  helping you propagate plants from cuttings successfully.
