I read a very interesting article recently and wanted to share it with you.

Interest in essential oils and their healing ability is at an all-time high. The more we learn about the amazing benefits of essential oils, the more it seems we want to learn. Nature has provided us with a potent array of natural anti-cancer compounds in common citrus fruits. Lime, lemon, orange, grapefruit, and tangerine all possess plenty of healing plant nutrients − and the essential oils derived from the rinds of these fruits are no exception.
Citrus essential oil has been used for centuries for relief from colds and flu. These oils have also been used for cleansing, purification, digestion, skin complaints, disinfecting and so much more.
Ancient healers might not have known it, but modern science confirms that citrus essential oil contains an interesting array of natural phytochemicals (plant-based chemicals) that have anti-cancer properties. Scientists have been studying the phytochemicals found in citrus essential oils for decades.
It’s All About Limonene
At first it was thought that the anti-cancer activity of citrus essential oil was mainly due to the high levels of antioxidants they contained. Closer inspection found that it had mainly to do with one special phytochemical found in citrus known as limonene. There are now over 200 research studies on limonene discussing its anti-cancer benefits.
The limonene content in citrus essential oil depends a little upon the growing conditions of the fruit trees and many other factors, but generally speaking, citrus oils contain significant quantities of limonene.
Limonene Content in Citrus Essential Oils
Lemon essential oil: 59-73% limonene
Lime essential oil: 50-60% limonene
Orange essential oil: 85-96% limonene
Tangerine essential oil: 85-93% limonene
Grapefruit essential oil: 88-95% limonene
There is plenty of scientific research on citrus essential oils, and especially on limonene. One 1984 study found that rats fed limonene had a 72% reduction in mammary tumors as well as regression of existing mammary tumors − with no toxicity.
A 1994 study (also on rodents), found that limonene helped not only to prevent mammary carcinomas but also had anti-tumor effects.
How much limonene was necessary for the animals to experience tumor regression and prevention? One interesting 1992 study found that a diet containing 7.5% limonene was sufficient for mammary tumors to completely regress.
That’s all very well and good for animals, but does limonene work for humans?
A 2015 study on human pancreatic cancer cells in vitro (in test tubes) found that limonene inhibited the growth of the cancer cells. It also inhibited cellular proliferation (rapid reproduction of a cell). Limonene also promoted apoptosis (programmed cell death cancer cells). Researchers noted that limonene had “cancer specific toxicity.”
