However, the anticancer characteristics of BCP and its derivative Beta-Caryophyllene oxide (BCPO) have been documented in several recent reports where BCP was found to directly inhibit cancer cells proliferation, induce cell cycle arrest, and enhance apoptosis in various types of cancers (listed in Table 1) including lung cancer [2,3,4,5] colorectal cancer [6], ovarian cancer [7], bladder cancer [8], liver cancer [9,10], pancreatic cancer [11], and breast cancer [12,13]. This evidence concerns the gene OPN1SW and breast carcinoma.
