Orange Essential OilOrange Essential Oil (Citrus sinensis) has a rich, fruity scent that lifts the spirit while providing a calming influence on the body. Orange oil brings peace and happiness to the mind. Orange oil is rich in the powerful antioxidant d-limonene and aids in maintaining normal cellular regeneration.* Orange may also be used to enhance the flavor of food and water. Orange has an approximate ORAC of 18,898 (TE/L). TE/L is expressed as micromole Trolox equivalent per liter.

Key Constituents:
Limonene — 85-96%
Myrcene — 0.5-3%

Applications: Orange essential oil can be used for arteriosclerosis, hypertension, cancer, insomnia and complexion (dull and oily), fluid retention and wrinkles.

Orange Essential Oil Research: Orange is rich in limonene which has been extensively studied for its ability to combat tumor growth in over 50 clinical studies.

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 Red every 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 following is a document scanned by Vicki from the Young Life Research Clinic newsletter from 2002 which has the limonene research in it!!! Please click on the link to download this file, so that you will have it in your computer from now on!!! You are welcome to print it out and share it with EVERYONE!

More from Vicki: We can help a LOT of people, educating them about using orange oil which is 95% limonene. 

To replicate the studies showing regression of cancer would require that someone ingest 10ml of orange oil every day. This is about 12 capsules.

Yes, 10 ml is about 12 capsules a day. That's a lot of essential oil, and yet, from an economic perspective, if it helps, it's probably the cheapest treatment available. 

Many people won't want to try it because when someone gets a diagnosis that may be terminal, they become very afraid, and I don't blame them. They will want to do exactly what their oncologist tells them to do, which is perfect. This information is simply intended to give people information which they can discuss with their oncologist, and perhaps the doctor will encourage them to use this treatment in addition to what he/she is prescribing. 

I have also been hearing from downline leaders that taking 6 caps a day encourages weight loss.

Vicki says: "I have now seen 7 cases.... out of 7.... who recovered from cancer using orange oil (some late stage)... The last 2 cases, which were both terminal, were kidney and uterine cancer. That's 7 out of 7 not 7 out of 100... Amazing!"

Please make sure that everyone knows about this research and order your therapeutic grade essential oils here!
