Turns out frankincense, an aromatic tree oil burned as incense and used frequently in Christian church services, may be helpful in treating bladder cancer, a study finds.

Scientists tested an enriched extract of frankincense — believed to be one of the gifts presented to baby Jesus from the three wise men — on human bladder cancer cells and normal bladder cells in laboratory experiments, according to a study published this month in the British Medical Council journal Complementary and Alternative Medicine.

The oil suppressed cancer growth and activated the mechanisms that worked to kill the cancerous cells, according to researchers from the University of Oklahoma, French news agency Agence France-Presse reports.

"Frankincense oil may represent an inexpensive alternative therapy for patients currently suffering from bladder cancer," lead researcher Doctor Hsueh-Kung Lin told AFP.
