Antifungal agent

Several studies have found that citronella oil has certain antifungal properties that may help weaken or destroy certain types of fungi that can cause health problems.

A 2013 study evaluated the antifungal activity of citronella oil against a strain of fungus known as Aspergillus niger. This common fungus is thought to cause lung và sinus infections in people with weakened immune systems.

The study found that citronella oil had the ability khổng lồ destroy the cell wall of the fungus và kill the organisms within the cell that can cause infection. This led the researchers khổng lồ suggest citronella oil may have the potential lớn be used as a safe and environmentally friendly fungicide.

An earlier study looked at the antibacterial and antifungal activity of ten essential oils và found that citronella oil was effective against all 12 fungi that were tested. The same study found that citronella oil managed to inhibit 15 of 22 bacteria, while eucalyptus, lemongrass, peppermint, và orange oils were effective against all 22 bacterial strains.

A publication from 2016 looked at the effectiveness of citronella và cinnamon oil in fighting Candida albicans, a fungus that can cause infections in the mouth và other parts of the body.

Both essential oils initially reduced the number of viable microorganisms. However, after 48 hours the effect wasn’t significant. The authors suggest that a daily application of a solution of either oil may be effective in reducing this fungus.


Wound healing

Based on recent research, citronella oil may have the potential khổng lồ speed up the healing of wounds. This may be of particular importance for people with diabetes, as wounds tend khổng lồ heal more slowly with this condition.

In a năm 2016 animal study, researchers looked at the effect that citronella oil had on the healing of Candida-infected wounds in a diabetic mouse model. The citronella oil had both an antifungal và anti-inflammatory effect. The researchers suggested that the combination of these two factors led to lớn accelerated wound healing.
