Grapefruit Essential OilGrapefruit Essential Oil (Citrus paradisi) has a fresh, citrus aroma that is energizing and uplifting. Rich in the powerful antioxidant d-limonene, it is nourishing to the skin. Grapefruit essential oil is a popular oil to use in conjunction with weight management programs like many coldpressed citrus oils. Grapefruit may also be used to enhance the flavor of food and water. Grapefruit has an approximate ORAC of 226,234 (TE/L). TE/L is expressed as micromole Trolox equivalent per liter.

Fragrance: Grapefruit essential oil is refreshing and uplifting. A 1995 Mie University study found that citrus fragrances boosted immunity, induced relaxation and reduced depresssion.

The Scent of Grapefruit

By David Stewart, Ph.D., R.A.

The major portion of any essential oil (99.99%) is composed of only three elements—Carbon, Hydrogen, and Oxygen—but Sulfur and Nitrogen also sometimes contribute key roles.

For example, the distinctive fragrance of grapefruit oil (Citrus paradisi) is due to a sulfur compound (1-p-menthen-8-thiol) in a tiny trace amount—less than one part per billion. That is an infinitesmal 0.0000001%. Yet its presence dominates the scent of grapefruit. While grapefruit oil is 95% d-limonene, that is not what we smell.

d-Limonene, in any concentration, is experienced as a faint orange-like aroma. Amazing as it seems, that one molecule in a billion of the sulfur compound is so strong that it overcomes the d-limonene and is easily picked up and distinguished by our sensitive noses. (Strong odors are a characteristic of most sulfur compounds, which are also found in garlic and the oil of garlic.)

Check it out. If you have a bottle of Young Living grapefruit essential oil handy,take a wiff and experience a molecule or two of that sulfur compound. You can impress your friends by saying, “Hmmm . . . I believe there is a trace of 1-p-menthen-8-thiol in this oil.”

While all of the citrus rind oils (orange, lemon, tangerine, mandarin, and lime) are mainly composed of d-limonene, they each have different fragrances and different therapeutic properties determined by their minor and trace constituents. Grapefruit, for example, can dissolve fat tissue and can be used to assist in weight loss and reduce cellulite. However, this property is not due to its main ingredient, but due to its minor and trace compounds in conjunction with the d-limonene. 

This is another illustration of why an essential oil needs to be harvested and produced as close to nature as possible without tampering with even the least of the ingredients.

Dear Ara,

You are funny! I appreciate your vote of confidence, and you must realize that we are pioneering this work together. I have been blessed to be in YL for 15 years, and have seen, firsthand, like you have, what works, and what does not...

I'm going to paste, below, three paragraphs out of an email I recently sent to some of the leaders in my group. I hope that it will be helpful to many.

Our group has been pioneering many concepts in Young Living. The most important is the use of orange oil for helping the body release cancer. When people are willing to ingest 10ml of orange oil every day (in capsules), this replicates the amount of limonene in the studies that were done which showed regression of cancer.

Share Nature's Healing and Open Your Young Living Account Today!Just recently while in Japan, a young woman of about 45 told me that she had been told last summer that her uterine cancer had spread throughout her body and she only had a month to live. The doctors said that due to her condition, they were not able to offer surgery or chemotherapy. After speaking with a Young Living leader there, she took 10ml of orange oil every day, in capsules. She also rubbed orange oil, frankincense, myrtle,sandalwood, and tsuga all over her belly every day, and she drank 4-6 oz. of NingXia Red each day, as well. She is now cancer free! These kinds of stories are starting to surface, and even though they are anecdotal, they will help us help others in the future! This is what keeps me going every day!

A personal story from one of the leaders in my organization:

"My Mother-in-law had a grapefruit-sized tumor on her only remaining kidney. Her other kidney had been taken to cancer 5 years earlier. The doctors could not treat her because of her deteriorating health so she began to take 10 ml of orange oil in capsules. She took 2 full capsules every 2 hours for eight hours a day. After 3 months the tumor was gone. She continues to take 1-4 capsules of orange oil and also drinks 2-4 oz. Ningxia Redevery day. Her cancer has not returned." C.D. Westwood, NJ

I am not a trained medical doctor, and I am not making any recommendations to anyone about anything. I am simply passing along what I have seen and heard. People need to use the best of both worlds - allopathic and natural medicine. If someone calls me and says that they have a lump in their breast, my response is, "Hang up the phone and call your gyn and make an appointment. Then call me back and let's talk about what we can do while you're waiting to see your doctor." PLEASE - let's NOT be irresponsible!

I cannot advise anyone about anything either. All I can share is what we know:

  1. Limonene has been shown through research to not only inhibit cancer, but also to regress it.
  2. Orange oil is 95% limonene. (This is why it is in our Longevity supplement)
  3. In order for us to replicate the amount of limonene used in the studies, we would have to ingest 10 ml of orange oil every day. For how long? I don't know. Until it was gone, I guess.

Other studies have shown that frankincense (which is 12% limonene), myrtle, sandalwood, and tsuga all have excellent inhibition of cancer cells. If I were using those oils, rubbed on my breasts (for prevention, which is what I do from time to time) or over an area of concern, I would use them neat (without dilution) and liberally (6-8 drops of each...), and often, perhaps even several times a day if I thought I had a problem.

Note: Grapefruit therapeutic grade essential oil contains the highest level of limonene: at 95.12%!

That's about all I can say. I think it's absolutely amazing that something as simple as orange oil, which is very inexpensive, might hold the key to the challenges with cancer...

Hope you all are healthy, happy, and taking Longevity morning and night, like I do.


The cancer process is swift and often goes unnoticed until drastic measures must be taken. the key is prevention with agents like the essential oil constiuent, limonene of which the highest concentrations are found in Grapefruit, Tangerine, Orange and Lemon therapeutic grade essential oils. Ingesting 10ml of therapeutic grade essential oil every day (in capsules), replicates the amount of limonene in the studies that were done which showed regression of cancer. "The phytonutrient limonene has been found in numerous animal and human studies to help stop cancer in its three stages: initiaion, promotion/progression and metastasis."

The Antidote to Lifestyle Suicide
A key constituent in citrus oils has been shown to prevent DNA damage linked to cancer and accelerated aging.
