Citronella oil, derived from the distillation of the Asian grass plant in the Cymbopogon genus, has a floral, citrus-like aroma. While it’s best known as a natural insect repellent, its uses extend beyond keeping bugs at bay. Let’s explore the benefits and how to use citronella oil:

1. Insect Repellent:

   • Citronella oil is commonly used as an insect repellent.

   • When combined with vanillin (found in vanilla beans), it provides mosquito protection for up to three hours.

   • However, it’s not as effective as DEET for long-lasting protection.

2. Antifungal Properties:

   • Citronella oil has antifungal activity against certain fungi, including Aspergillus niger, which can cause infections in people with weakened immune systems.

3. Other Uses:

   • Citronella oil has been historically used for wound healing, mood enhancement, and flavoring in food and perfumes.
