Citronella is credited with having therapeutic properties as an antiseptic, deodorant, insecticide, parasitic, tonic and as a stimulant. Nonetheless, most people will associate it with its insecticide properties. Many commercial repellents contain Citronella and it is often used in combination with Cedarwood to produce a pleasant smelling natural insect repellent. This oil can also help with minor infection, but is more commonly known for its ability to assist in combating colds and flu. Citronella can also be used for excessive perspiration and for conditioning oily skin and hair.
