The findings of one 2015 study suggest that breast cancer cells may stop growing and die off when exposed to frankincense oil. The researchers concluded that their approach is cost-effective and less time consuming than other methods.
Researchers in a 2009 study looked exclusively at frankincense oil derived from the Boswellia carteri species and assessed its anti-tumor activity on bladder cancer. Researchers concluded that, when administered, the oil appears to differentiate between healthy and cancerous cells. The oil can also suppress cancer cell viability.
Similar results were found in a 2011 study assessing the effects of oil from B. sacra on breast cancer cells.
