Basil Cultivars and Essential Oil Production
Basil is a herbaceous plant belonging to the Lamiaceae family, which is native to tropical regions of central Africa and Southeast Asia. There are several cultivars of basil, each with unique characteristics in terms of aroma, flavour, and essential oil composition. Some of the most popular cultivars used for essential oil production include sweet basil (Ocimum basilicum), holy basil (Ocimum tenuiflorum), and African basil (Ocimum gratissimum).
Steam distillation is the most common method used for the extraction of essential oils from basil plants. During this process, steam is passed through the plant material, which causes the essential oil to evaporate and then condense into a liquid. The resulting liquid is a mixture of water and essential oil, which is then separated using a separator or decanter.
The yield and quality of essential oil depend on several factors, including the basil cultivar, the plant’s age, and the time of day when the plant is harvested. For instance, sweet basil harvested in the morning has been found to contain higher levels of essential oil than those harvested in the afternoon. Furthermore, the essential oil composition of basil can vary depending on the geographical location, soil type, and climate conditions.
Studies have shown that basil essential oil contains several bioactive compounds, including eugenol, linalool, methyl chavicol, and geraniol. These compounds possess antimicrobial, anti-inflammatory, and antioxidant properties, which make basil essential oil a promising candidate for various therapeutic applications.
In conclusion, basil essential oil is extracted from different cultivars of basil using steam distillation. The yield and quality of essential oil depend on several factors, including the cultivar, the age of the plant, and the time of day when the plant is harvested. Basil essential oil contains several bioactive compounds that have potential therapeutic benefits.
Clinical Trials and Research Studies
Over the years, several clinical trials and research studies have explored the potential benefits and uses of basil essential oil. Here are some of the most notable ones:

Basil essential oil has been found to have a significant repellent effect against a variety of insects, including mosquitoes, ticks, and flies.
A laboratory trial by Amer et al. found that a 20% oil solution of basil essential oil had a mean percentage repellency of 66.7% and provided 100% protection against Anopheles stephensi for 3.5 hours. Phasomkusolsil et al. used basil essential oil at 0.02, 0.10, and 0.21 mg/cm2 concentrations against Anopheles dirus. The percentage repellency was dose-response, and the results showed that basil essential oil has a significant effect in repelling insects, especially at higher concentrations.
Petitgrain oil was found to be the most effective against Aedes aegypti, with a repellent activity of 270 minutes, according to a study by Trongtokit et al. However, basil essential oil also showed a significant repellent effect against Aedes aegypti, with a mean percentage repellency of 96.5% at a concentration of 10%.
Plant-based repellents have gained increasing popularity due to their natural and safe properties. Basil essential oil is a promising natural insect repellent due to its significant repellent effect against a variety of insects. However, further research is needed to explore its effectiveness in different settings and against different species of insects.
In conclusion, basil essential oil has shown significant potential as an insect repellent in various studies. Its natural properties make it a promising alternative to chemical insect repellents.
