Citronella Grass
True citronella, cybopogon nardus or citronella winterianus, is a perennial, clumping grass, which grows five- to six-feet tall. Citronella is closely related to lemon grass. Many people confuse citronella with the commercially sold "mosquito plant," citronella geranium, which is actually a scented geranium. The aromatic, gray-green grass originated in China, which exports the majority of the essential oil on the market.
Citronella Oil
Steam-distilled leaves, dry or fresh, produce thin, yellow/tan oil with a fresh, lemony smell. Citronella oil is considered volatile -- organic compounds that easily evaporate and are regulated by government agencies. The length of potency varies with the amount of citronella oil in a product. The oil contains alcohols -- geraniol and citronellal -- as well as citronellic acid, camphor and limonene.
Uses
By spraying or scattering the leaves in recreational areas or around trees and shrubs, the aromatic scent deters insects by hiding the smell of the human host. The topical antiseptic qualities constitute a "green" household disinfectant. Citronella softens the skin and aids in combating perspiration, especially on the feet. The oil mixes well with carrier oils or lotions for skin applications, such as muscle rubs. An essential oil vaporizer or burner diffuses the aroma for a therapeutic uplifting effect.
Risks
According to the Environmental Protection Agency (EPA), oil of citronella presents no threat of toxicity to laboratory animals. The EPA also states there are no adverse effects on the environment, so it's safe for home use. The only adverse reaction was skin irritation. Due to the application to human skin, manufacturers must label citronella oil with a precautionary warning.
