Boswellia for Brain Cancer Treatment Side Effects?

study PMID: 39993542

Quick Summary: A recent study suggests that Boswellia serrata, a natural supplement, may help reduce swelling and improve symptoms in people who have brain problems after radiation therapy for cancer that has spread to the brain.

What The Research Found

This study looked at how Boswellia serrata (also known as frankincense) affected people with radiation necrosis (RN). RN is a side effect that can happen after radiation therapy for brain tumors. The study found:

Reduced Swelling: 70% of patients had less swelling in their brains, as seen on MRI scans.

Symptom Relief: 65% of patients reported feeling better, with fewer headaches and improved thinking.

Less Steroid Use: 55% of patients were able to reduce or stop taking steroid medications, which are often used to treat this condition.

Study Details

Who was studied: 20 adults who developed RN after radiation treatment for brain tumors that had spread from other cancers.

How long: Patients took Boswellia for 6 weeks.

What they took: Patients took 400mg of Boswellia serrata three times a day (1200mg total), in capsule form with meals.

What This Means For You

If you've had radiation therapy for brain tumors and are experiencing side effects like swelling or headaches, Boswellia serrata might be a helpful option. This study suggests it could reduce swelling and improve symptoms. It may also help you reduce your reliance on steroids, which can have side effects of their own. Always talk to your doctor before starting any new supplement, especially if you are already taking medications.

Study Limitations

It's important to know that this study has some limitations:

Small Study: Only 20 people were in the study, so more research is needed.

No Comparison Group: The study didn't compare Boswellia to a placebo (a "dummy" pill) or another treatment.

Short-Term Results: The study only looked at results for 6 weeks, so we don't know the long-term effects.

Different Cancers: The patients had different types of cancer, which could affect the results.

More Research Needed: Larger studies are needed to confirm these findings.

Key Findings

This 2025 study found that Boswellia serrata (BS) supplementation reduced cerebral edema and symptoms in patients with radiation necrosis (RN) following stereotactic radiosurgery (SRS) for brain metastases. A 70% response rate (14/20 patients) was observed for edema reduction on MRI, with 65% (13/20) reporting symptom improvement. Additionally, 55% (11/20) of patients reduced or discontinued corticosteroid use. The supplement was well-tolerated, with no significant adverse events reported.

Study Design

The study was a prospective, open-label, single-arm trial involving 20 adults diagnosed with RN after SRS for brain metastases. Participants received BS for 6 weeks, with outcomes assessed via MRI volumetric analysis of edema and patient-reported symptom scales. The median follow-up period was 6 weeks post-treatment initiation.

Dosage & Administration

BS was administered orally at 400 mg three times daily (total 1,200 mg/day), standardized to contain 65% boswellic acids. Capsules were taken with meals to enhance absorption. Compliance was monitored via pill counts, and adverse events were tracked throughout the study period.

Results & Efficacy

Edema reduction: MRI showed a median decrease of 35% in edema volume (range: 15–60%) after 6 weeks (p < 0.05).
Symptom improvement: 65% of patients reported reduced neurological symptoms (e.g., headaches, cognitive deficits) on standardized scales (p = 0.02).
Corticosteroid sparing: 55% of patients tapered or stopped corticosteroids without worsening symptoms.
Safety: No grade ≥3 toxicities or treatment-related adverse events were recorded.

Limitations

Small sample size: Only 20 patients were enrolled, limiting statistical power.
Lack of control group: Open-label design without a placebo or comparator arm introduces potential bias.
Short duration: Outcomes assessed over 6 weeks; long-term efficacy/safety unknown.
Heterogeneous population: Varied primary cancer types (e.g., lung, breast, melanoma) and RN severity at baseline.
Need for validation: Results require confirmation in larger randomized controlled trials (RCTs).

Clinical Relevance

For patients experiencing RN after SRS, BS may offer a safe, natural alternative to corticosteroids for managing edema and symptoms. The 70% radiographic response rate and 65% symptom improvement suggest potential utility, though the absence of a control group warrants caution. Supplement users should consult healthcare providers before discontinuing steroids or starting BS, as individual responses may vary. Future research should prioritize RCTs to establish definitive efficacy and optimal dosing.
