"Clinical Summary
Derived from the peels of citrus fruits, D-limonene is used by patients to prevent and treat cancer and has been promoted as a treatment for gastroesophageal reflux. Following oral administration, D-limonene is rapidly metabolized to limonene-1,2-diol, perillic acid, dihydroperillic acid, and uroterpenol (1) (2) (3).
In vitro and animal studies suggest that D-limonene has anti-inflammatory (13), bactericidal (19) and anticancer effects (14) (16) (17) (18). It was also shown to enhance the activity of docetaxel against prostate cancer cells (15).
An epidemiological study reported an inverse relationship between citrus peel consumption and squamous cell carcinoma (4), but an early clinical trial in breast cancer patients failed to support the observations (5) (6).
Further research is necessary to determine if D-limonene has a role in the prevention or treatment of cancer."
