Basil Essential Oil

Basil (Ocimum basilicum L.) is an edible, fragrant leafy herb belonging to the Lamiaceae family, sporting deep green leaves on the upper side and green-gray underneath.7 Hailing from the Greek word basileus meaning ‘king’ basil is popular for its fragrant leaves, and often referred to as ‘king of the herbs’.2

The herb originated in India and was introduced to the Mediterranean on the spice routes during ancient times. Holy basil, or ‘tulsi’, is the most notable of the more than 50 different types of basil now grown in Asia, Africa, Central and South America, Canada and the United States.3

Basil leaves are sweet when picked early and become spicy as they ripen. They produce an aromatic essential oil, that is extracted through steam distillation. This process involves boiling the plant material until the oil is separated and captured in an inhaler.4

Using a personal aromatherapy inhaler, test subjects were randomized into a control group which used rose water, or the experimental group. The mixture was inhaled at home or at work, up to 7 times a day for three weeks.1

Results suggest that while both groups experienced improvements in the perception of mental exhaustion or moderate burnout, the aromatherapy group reported a 21% improvement, compared to 11% in the control group.1

One study looked at the effects of basil essential oil on Giardia lamblia (a parasite in the small intestine), and found that linalool, a pure concentrate of basil, killed 100% of parasites after one hour of incubation.8
