Boswellia / Frankincense and cancer

What is boswellia

Boswellia, also known as frankincense, is a resin-like substance extracted from the bark of Boswellia trees [3, 4]. It has been used in traditional medicine for centuries to treat a variety of conditions, including arthritis, inflammation, and asthma. However, boswellia has also shown potential in the treatment of cancer [1, 5].

Effect of boswellia

Anti-inflammatory effect

Boswellia possesses anti-inflammatory, anti-carcinogenic, and immunomodulating properties [5, 9]. The active components, boswellic acids, inhibit the production of leukotrienes—inflammatory substances that promote the growth and spread of cancer cells [1].

Antibacterial

Furthermore, boswellia may also possess antibacterial and antiviral properties.

Application of boswellia

Boswellia is available in capsules, tablets, creams, and ointments. Oral ingestion or topical application to the affected area are possible options.

Advantages

Research suggests that boswellia may offer the following benefits in cancer treatment:

Reducing inflammation

Chronic inflammation is associated with carcinogenic processes. Boswellic acids can dampen inflammation and thereby inhibit cancer growth [5, 9].

Killing cancer cells

Studies have shown that boswellic acids can induce apoptosis (cell death) in various cancer cell lines [8, 11, 12].

Improving the immune response

Boswellia can strengthen the immune system’s ability to recognize and attack cancer cells.

Alleviating side effects of cancer treatment

Boswellia can potentially reduce pain, nausea, and fatigue associated with chemotherapy and radiation therapy [4, 7].

Relieving radiation damage

Boswellia serrata may be a safe and effective treatment for cerebral radiation necrosis (brain tissue death) following stereotactic treatment, with many patients experiencing improvement without major side effects [2, 10]. Further research is needed to confirm its efficacy.

Disadvantages

Side effects of boswellia are mild and include stomach upset, diarrhea, and nausea. In rare cases, allergic reactions may occur.

Important

Research on boswellia in cancer treatment is ongoing, and more evidence is needed to confirm its effectiveness and safety. Consultation with a doctor is essential before starting boswellia supplements, especially if you are undergoing cancer treatment or taking other medication.

The future

Boswellia has been shown to have a range of positive effects that can support cancer treatment. In addition to the mentioned properties, boswellia can also contribute to improving the quality of life in patients by reducing chronic inflammation, which is often associated with carcinogenic processes. Furthermore, its ability to induce apoptosis in cancer cells offers hope that it can be used as a supplementary therapy in future treatment regimens [11, 13]. Research also suggests that boswellia can promote healing by supporting the body’s natural immune response, which can be crucial in fighting the disease. These positive aspects make boswellia an interesting topic in ongoing oncology research.

Conclusion

Boswellia, also known as frankincense, is a resin-like substance with a long history in traditional medicine, particularly for treating inflammation, arthritis, and asthma.

Research suggests that boswellia has promising anti-inflammatory, antibacterial, and immunomodulating properties that may be beneficial in cancer treatment. The active components, boswellic acids, can reduce inflammation, kill cancer cells, and strengthen the immune response [1, 5].

Additionally, boswellia can help alleviate side effects from cancer treatment, such as pain and nausea [7, 14]. Although side effects are generally mild, it is important to note that more research is needed to confirm boswellia’s effectiveness and safety.

About the Author & Professional Background

Portrætfoto af Hanne til forsiden.

This article has been prepared and validated by the undersigned, Hanne Kjær Uhlig. I am a registered nurse (1975, with clinical experience until 2013) and hold an M.Arch. (1983, specializing in industrial design), and I taught at DTU (Technical University of Denmark) for a number of years.

Following the loss of my mother to cancer in 2000 and my own cancer diagnosis in 2024, I founded this non-profit information site “Jeg har Kræft” (I Have Cancer).

The goal is to use my analytical and academic approach to bring clarity, safety, and scientific evidence to the field of integrative, complementary, and alternative cancer treatment. At the same time, my healthcare experience is utilized to make the articles patient-centered and relevant.

Article characteristics:

  • Clinical and personal background: Created from a combination of decades of experience as a nurse and personal experiences as both a patient and a relative.
  • Scientific methodology: The content is based on systematic research of medical databases and clinical trials. The articles are consistently supported by source references under Links.
  • Independent non-profit project: Operations are funded through voluntary donations and memberships through the Support Association Jeg har Kræft. The site is completely independent of commercial manufacturer interests and works solely to improve the quality of life for cancer patients.
