Known for its tangy taste and sweet and energizing scent, grapefruit is a fruit of an evergreen citrus tree. Grapefruit essential oil, also known as Shaddock, is derived from the rind of this citrus fruit.
The stimulating and energizing aroma of this oil makes it a popular ingredient in lotions, shampoos, body washes, and even scented candles.
However, this is not the only benefits that this citrus-scented oil offers. The diuretic, antiseptic, stimulant, antidepressant and disinfectant properties of grapefruit oil provide numerous health benefits.
Read on to learn more about what is grapefruit essential oil and what health benefits it offers.
What is grapefruit essential oil?
Grapefruit essential oil (Citrus Paradisi) is extracted from the glands located on the peels of the grapefruit through cold pressing.
The oil glands in grapefruit are located deeper in the peel as compared to other citrus fruits, so it is more difficult to extract this oil.
When compared to other citrus fruits like orange and lemon, grapefruit produces much lesser essential oil, which is the reason why it is more expensive.
This orange-tinted, citrus-scented oil is rich in antioxidants and phytochemicals that reduce oxidative stress and inflammation.
This essential oil is composed of limonene, sabinene, alpha-pinene, myrcene, geraniol, linalool, citronellal, decyl acetate, neryl acetate, and terpineol.
Its main chemical component, limonene, is known for its tumor-fighting and cancer-preventive properties.
