a) As Food: In foods and beverages, citronella oil is used as a flavoring. 
b) As Medicine: 
In addition to antibacterial properties, Citronella serves as an anti-fungal and antiviral agent. The anti-fungal properties found in citronella make it a popular herb for treating intestinal parasites when used under the supervision of a certified herbalist or health professionals. In Chinese medicine, Citronella is prescribed to treat aches and pains in muscles and joints. When added to a carrier oil, three drops of citronella oil massaged into the muscle will help alleviate aches.Citronella oil can help treat oily skin. After washing the face with a mild cleanser, add a dab of oil to a cotton ball and gently swipe it across the problem areas. The antibacterial properties present in citronella will also help to clear up blemishes and remove dirt and debris clogging the pores. For sweaty feet, a swipe from a citronella cloth or a spritz of spray will alleviate perspiration and leave the feet feeling cool and refreshed.

c) Other Uses: Citronella oil is a widely used ingredient in natural insect repellents. Although commonly used as a spray, these repellents also come in pure oils and cream form. A cotton ball soaked in citronella oil and placed on a windowsill can help keep mosquitoes and other insects from entering the home. Citronella oil diffusers work well when placed outside on a dining table. Citronella-based collars also protect pets from fleas and ticks, as does spraying the oil directly on an animal’s coat.

3) Growing Instructions

a) Growing: Citronella grass can also be grown as an annual grass where the growing season is both warm enough and long enough. As it grows, the grass forms a clump often as wide as it is tall, and can reach from 5 to 6 feet (1.5 to 1.8 m) in optimal growing conditions. Citronella grass typically requires at least 30 inches (76 cm) of water per year to thrive.
