Many modern insect repellents are made from citronella.
Citronella oil is an essential oil. An essential oil is derived from plant materials by different methods, such as distillation, and carries the "essence" or unique scent, of the plant. Citronella oil, made from from cultivated grasses, has long been used as a natural repellent for mosquitoes and other insects. Known for its minimal environmental impact, citronella oil has many other uses as well. Does this Spark an idea?
Insect Repellent
The most common use of citronella is as an insect repellent. Citronella, when inhaled, gives an initial stimulation before depressing the central nervous system. In humans, the effect is minimal, but it is bad enough for mosquitoes to steer clear of the fumes. Citronella is used in aerosol sprays, patches, pods and candles with the intent of keeping an area clear of mosquitoes. Citronella can also be found in dog collars as a way to repel fleas.
Aromatherapy
Citronella oil is now also commonly being used as an aromatherapy product as well. Though not used extensively due to its connotation with insect repellents, citronella mixes very well with other citrus smells, according to AromaWeb.com. Oil of citronella also has the ability to warm the skin, especially in the hands of a skilled masseuse. Citronella can also help with mental fatigue because of the oil's clarifying properties, which heighten senses and help to wake you up.
Astringent
Oil of citronella has also been used as an astringent -- it helps to remove excess oil from the skin. To test for irritation, rub a drop of citronella on the inner forearm and let it stand for a few hours, to see if any rash occurs. If none does, it is safe to say that the oil can be used on the rest of your skin. Consult a doctor if you believe you are having an allergic reaction or other problem. You can use a few drops on a cotton ball and rub on your face before continuing with your normal facial routine.
Other Uses
Citronella has also been used for various other purposes, although none have been tested extensively. Oil of citronella from the Java species of plant is used as a building block in many perfumes. Some chefs even use citronella to flavor foods. Some aromatic teas use citronella as a diuretic, vermifuge (to expel intestinal worms) or antispasmodic (to suppress muscle spasms), according to Drugs.com. No health risks have been associated with the use of citronella oil, although many attribute this to lack of clinical trials. Use discretion when testing this product.
