What Is Emu Oil? Other Names: Aceite de Emu, Bush Chook, Dromiceius Nova-Hollandiae

What is Emu Oil?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Emu oil is a natural oil derived from the fat of the emu, a flightless bird native to Australia. It has gained attention for its potential health benefits, particularly due to its rich composition of fatty acids, including monounsaturated and polyunsaturated fats. Other names include: Aceite de Emu, Bush Chook, Dromiceius Nova-hollandiae, Dromiceius novahollandiae, Émeu, Emu, Huile d’Émeu.

Composition and Properties

Emu oil is predominantly composed of fatty acids, with a high content of oleic acid, a monounsaturated fatty acid. It also contains linoleic and linolenic acids, which are essential fatty acids known for their health benefits. These components contribute to emu oil’s anti-inflammatory and moisturizing properties, making it a popular choice in both traditional and alternative medicine1 4 8.

Health Benefits of Emu Oil

Anti-Inflammatory Effects

Emu oil has been studied for its anti-inflammatory properties. Research indicates that it can reduce inflammation in various conditions. For instance, it has been shown to decrease acute inflammation in a rat model of mucositis, a common side effect of chemotherapy, by reducing neutrophil activity and improving intestinal health3. Additionally, emu oil has demonstrated potential in reducing inflammation in inflammatory bowel diseases, such as ulcerative colitis, by improving colonic tissue health4 9.

Skin Health

Emu oil is also used for its skin-healing properties. It has been tested in the treatment of radiation dermatitis, where it showed a trend towards reduced skin toxicity, although further studies are needed to confirm its efficacy2. In burn wound healing, emu oil was found to delay the healing process but increased the number of hair follicles and collagen synthesis, suggesting a complex role in skin repair5.

Cardiovascular Health

The oil’s high oleic acid content is believed to contribute to its potential cardiovascular benefits. Studies on diet-induced obese rats have shown that emu oil supplementation can lower inflammation and prevent atherosclerosis, a condition characterized by the buildup of plaques in the arteries1 8. This suggests that emu oil might help in managing cholesterol levels and reducing the risk of heart disease.

Potential Uses

Emu oil is used both topically and orally. Topically, it is applied to the skin for its moisturizing and anti-inflammatory effects, while oral consumption is explored for its potential benefits in reducing inflammation and improving gut health6 10. It is also being investigated for its role in managing joint pain, particularly in conditions like osteoarthritis10.

Adverse Effects of Emu Oil

Radiation Dermatitis: In a study evaluating emu oil for preventing radiation dermatitis, patients using emu oil showed a trend towards reduced skin toxicity compared to a placebo. However, the study noted that patients using emu oil appeared slightly worse on maximum toxicity grades, though this difference was not statistically significant, suggesting that emu oil is generally safe for skin application during radiation therapy1.

Joint Pain: Another study assessed the use of emu oil for joint pain in postmenopausal women using aromatase inhibitors. The study found no statistically significant adverse effects from emu oil, indicating its safety for topical use in this context2.

Atherosclerosis: In animal studies, emu oil supplementation was associated with positive effects, such as decreased atherogenic plaque formation and improved lipid profiles, without reported adverse effects. This suggests that emu oil may be safe for consumption in controlled doses3.

How has Emu Oil Improved Patient Outcomes?

Skin and Radiation Therapy

Emu oil may reduce skin toxicity in patients undergoing radiation therapy. A pilot study indicated a trend towards reduced skin-related side effects, such as rash and redness, in patients using emu oil compared to a placebo, although the difference was not statistically significant. Quality of life measures were slightly better in the emu oil group1.

Joint Pain and Osteoarthritis

For joint pain, particularly in postmenopausal women using aromatase inhibitors, emu oil showed a significant improvement in pain and functional interference scores, although it was not statistically superior to placebo2. In osteoarthritis of the hands, emu oil was suggested to help manage pain, with improvements potentially observable after three weeks of treatment5.

Seborrheic Dermatitis

Emu oil has been effective in improving symptoms of seborrheic dermatitis, such as itching and erythema, although it was less effective than standard treatments like hydrocortisone and clotrimazole for certain symptoms3.

Inflammatory Bowel Disease and Colitis

In animal models, emu oil has demonstrated the ability to reduce inflammation and improve intestinal health. It decreased acute inflammation and improved mucosal architecture in a rat model of chemotherapy-induced mucositis6. Additionally, it reduced colonic damage severity and increased crypt depth in a model of ulcerative colitis, suggesting potential benefits for inflammatory bowel diseases7.

Cancer and Colitis-Associated Tumors

In combination with Saireito, emu oil reduced disease activity and tumor development in a mouse model of colitis-associated colorectal cancer, indicating its potential therapeutic role in such conditions4.

Emu Oil Mechanisms of Action

Anti-Inflammatory Effects

Emu oil has demonstrated significant anti-inflammatory properties in various models. It reduces acute inflammation in the intestine, as seen in a rat model of mucositis, by decreasing activated neutrophil activity and improving mucosal architecture3. It also reduces auricular inflammation in mice, indicating its potential to alleviate acute inflammatory responses7.

In models of inflammatory bowel disease, emu oil has been shown to reduce colonic damage and improve tissue architecture, suggesting its utility in managing conditions like ulcerative colitis6 8.

Lipid Modulation and Hormonal Effects

Emu oil supplementation in diet-induced obese rats has been shown to lower lipid profiles and modulate hormonal profiles, which contributes to its anti-atherosclerotic effects. This is likely due to the high oleic acid content, which may upregulate testosterone biosynthesis and prevent atheromatous plaque formation1 2.

Wound Healing and Tissue Regeneration

While emu oil may delay the initial healing process of burn wounds, it positively affects fibrogenesis and collagen synthesis, enhancing hair follicle activity and maturity in the wound margins5.

Potential in Cancer Models

In a mouse model of colitis-associated colorectal cancer, emu oil, especially when combined with Saireito, reduced disease severity and tumor development, indicating its potential therapeutic role in cancer-related inflammation4.

Common Complaints Associated with Emu Oil Use

Findings from Studies

Safety in Radiation Therapy: A pilot study on the use of Ultra Emu Oil for patients undergoing radiation therapy found it to be safe, with a trend towards reduced skin toxicity compared to a placebo. There were no significant adverse effects reported, although patients using emu oil showed slightly worse maximum toxicity grades, which were not statistically significant1.

Anti-Atherosclerotic Effects: In a study on obese rats, emu oil supplementation was found to decrease atherogenic plaque formation, suggesting its potential in reducing inflammation and preventing atherosclerosis. The study did not report any adverse effects related to emu oil use in this context2.

Colitis-Associated Colorectal Cancer: Emu oil, alone or in combination with Saireito, was shown to reduce disease severity and tumor development in a mouse model of colitis-associated colorectal cancer. The study highlighted its therapeutic potential without mentioning any negative side effects3.
