Imperata Cylindrica Root Extract


Imperata cylindrica root extract is extracted from the roots of the Imperata cylindrica, also known as cogongrass, native to Asia, Oceania, and Australia. The roots and leaves are used to treat wounds and sores in Indonesian traditional medicine.

According to the patent holder, the extract contains significant amounts of potassium and sulfur-containing proteins, which are claimed to have humectant moisturizing and anti-wrinkle properties. No scientific study exists that can support or disprove this claim, however.

An interesting fact unrelated to skincare is that cogongrass is highly flammable and causes rapid and extremely hot wildfires. After the fire, the plant is able to regenerate from its root system.
