Preliminary studies indicate that the limonene contained in orange essential oil is associated with a decreased risk of several types of cancer, including squamous cell carcinoma of the skin, colon, and breast cancer . Although researchers are still studying how limonene does this, they do know it decreases the expression of tumor markers by 22%, particularly cyclin D1, which occurs with over half of invasive breast cancers .
Limonene has also been found to help alleviate the often painful symptoms associated with gastro-esophageal reflux disorder (GERD), although researchers have yet to determine exactly what makes it so effective .
