Frankincense oil derived from Boswellia carteri induces tumor cell specific cytotoxicity
While promising, additional research, including human clinical trials, are necessary.
While many attribute the anticancer activity of frankincense resin solely to the presence of boswellic acids, research suggests that the volatile compounds within the resin are also active. Laboratory research has found that frankincense essential oil kills breast, pancreas, and bladder cancer cells.
