The short answer
Frankincense (from boswellia trees) is promoted online as a natural cancer cure. Some laboratory studies of concentrated boswellia extracts show effects on cancer cells in a dish or in animals, but this is not the same as the essential oil sold in shops, and there is no reliable evidence it cures cancer in people. Using it instead of proven treatment is the real risk.

The full explanation.
The claim
Frankincense essential oil — from the resin of boswellia trees — is widely promoted online as a natural cancer treatment or cure, often with references to laboratory studies as proof. It is sold in health shops and marketed for many conditions.
What the lab research shows
Some laboratory studies have found that concentrated boswellia extracts, and compounds such as AKBA, can affect cancer cells grown in a dish or in animal models. These early findings are why researchers are interested. But effects on cells in a dish frequently do not carry over to people, and studies like these cannot show that a product cures cancer in humans.
Why this is not proof
There is an important gap between the research and the products for sale. Much of the lab work uses purified plant extracts or specific compounds, not the essential oil found on store shelves. And there is no completed, reliable human evidence showing frankincense treats or cures cancer. Interest in the laboratory is not the same as an effective, proven therapy.
The bottom line
Based on current evidence, frankincense oil is not a proven cancer cure. Early laboratory research is a reason to study it further, not a reason to rely on it. The real danger is using it instead of, or to delay, treatment that is known to work. If you are considering any complementary product, tell your care team first.

Common questions
▸Does frankincense oil cure cancer?
No reliable human evidence shows it cures cancer. Lab studies of concentrated extracts are not the same as the oil sold in shops treating people.
▸But aren't there studies showing it kills cancer cells?
Some lab studies show effects on cancer cells in a dish or in animals, but those results often do not carry over to people.
▸Is the oil in shops the same as what was studied?
Usually not. Much research uses purified plant extracts or specific compounds, not the commercial essential oil.
▸What is the main risk?
Using frankincense instead of, or to delay, proven cancer treatment.
