Pure emu oil of oral grade quality

Blend of shea butter medium chain triglycerides, almond oil and carrot oil

Level 2

No statistical difference between the control and emu oil group for joint pain as assessed by VAS (p = 0.042) and BPI (p = 0.76)

Adults with histologic evidence of primary invasive breast carcinoma or ductal carcinoma in situ, who were to undergo a panned course of continuous, definitive or adjuvant external beam radiation therapy to the whole breast or to the chest wall.

2-arm, double blinded, randomized pilot study

No significant statistical difference. The Skindex 16 area and the curve scores were decreased in the emu oil patients (AUC = 7.2) when compared to placebo (AUC = 10.4), however p = 0.29.
