Diverticulitis is a digestive condition that arises from inflammation or infection of small pouches, known as diverticula, which develop in the walls of the large intestine (colon). While these pouches are usually harmless, they can become inflamed or infected, leading to painful symptoms such as lower abdominal pain, fever, nausea, and changes in bowel habits. This discomfort often occurs when food particles get trapped in the diverticula, triggering an infection. Although the precise cause of diverticulitis remains unclear, it is commonly associated with a low-fiber diet, which can contribute to constipation and increased pressure inside the colon.
While treatment for diverticulitis typically involves dietary changes, lifestyle adjustments, and, in severe cases, antibiotics or surgery, there has been growing interest in natural remedies like Manuka honey. Known for its potent antibacterial properties, Manuka honey may offer benefits in managing infections related to diverticulitis. But how realistic are these claims? Let’s explore the potential role of Manuka honey in managing diverticulitis symptoms.
Understanding Diverticulitis and Its Challenges
Diverticulitis presents a range of symptoms, most notably abdominal pain (usually on the lower left side), but it can also involve fever, digestive changes, and sometimes severe complications. When food particles or waste material become lodged in the diverticula, bacteria can multiply, causing infection. One of the common culprits in diverticulitis-related infections is Clostridium difficile (C. difficile), a bacterium that thrives when the balance of healthy gut bacteria is disrupted, especially during inflammation or after antibiotic use.
In mild cases, diverticulitis may be treated with rest, dietary changes, and antibiotics to control infection. However, given the increasing concerns over antibiotic resistance, alternative therapies have become a subject of significant interest. This is where natural substances like Manuka honey, with its antimicrobial properties, might have potential as a complementary therapy.
Manuka Honey’s Antibacterial Properties
Manuka honey, derived from the Manuka tree in New Zealand, has potent antibacterial effects due to its high concentration of Methylglyoxal (MGO). Studies have shown that Manuka honey is effective against various bacteria, including E. coli, Salmonella, and Staphylococcus aureus, which are known to cause gut infections. Laboratory research has also demonstrated that Manuka honey can kill C. difficile, although it does not completely eliminate the spores.
These findings suggest that Manuka honey could be beneficial in reducing the bacterial load in the gut during diverticulitis flare-ups. However, these results are primarily based on lab studies, and more clinical research is needed to confirm its effectiveness in people with diverticulitis.
Supporting Gut Health with Manuka Honey
In addition to its antibacterial properties, Manuka honey may support gut health by promoting the growth of beneficial bacteria. Research shows that it acts as a prebiotic, fostering the growth of probiotics like Bifidobacterium spp. and Lactobacillus spp., which are crucial for maintaining a healthy gut microbiome. A balanced gut microbiome can help prevent recurring infections and inflammation that lead to diverticulitis symptoms.
This prebiotic effect may support long-term gut health, but further studies are necessary to determine how Manuka honey specifically impacts those with diverticulitis.
Can Manuka Honey Relieve Symptoms of Diverticulitis?
Though there is no direct evidence linking Manuka honey to treating diverticulitis, its antibacterial and prebiotic properties suggest it could help manage related symptoms. For instance, by reducing harmful bacteria and supporting beneficial ones, it may help lower the risk of infection during flare-ups.
Some anecdotal evidence suggests that Manuka honey can soothe digestive discomfort, and reputable sources, such as Stanford Health Care, recommend honey during diverticulitis flare-ups. Many individuals report that consuming one tablespoon of Manuka honey daily, either directly or mixed with warm water, may help alleviate symptoms.
However, responses to natural remedies vary, and Manuka honey should not be seen as a substitute for medical treatment. It is best used as a complementary therapy under a doctor’s supervision.
Synergistic Effects with Antibiotics
An interesting aspect of Manuka honey is its potential to work synergistically with antibiotics. Research has shown that methylglyoxal in Manuka honey can enhance the effects of antibiotics like Piperacillin, which is used to treat diverticulitis-related infections. This synergy could allow for lower antibiotic doses, reducing the risk of antibiotic resistance.
For individuals already undergoing antibiotic treatment, using Manuka honey as a complementary therapy may offer additional benefits, but it is crucial to consult a healthcare provider before combining treatments.
Safely Incorporating Manuka Honey into a Diverticulitis Diet
For those interested in trying Manuka honey, it’s important to introduce it gradually and ensure that it’s part of a broader, balanced approach to managing diverticulitis. Here are some ways to safely incorporate it into your diet:
- Start Small: Start small: Begin with 1-2 teaspoons per day to assess your body’s response, and gradually increase to 1 tablespoon if tolerated.
- Add to Herbal Teas: Manuka honey can be mixed into herbal teas like ginger or chamomile, both of which may also help soothe the digestive tract.
- Use High-Quality Honey: Opt for raw, unpasteurized Manuka honey with a Unique Manuka Factor (UMF) rating of 15+ to ensure it contains effective levels of MGO.

Important Considerations
While Manuka honey shows promise for managing symptoms of diverticulitis, it’s crucial to remember that this is not a cure. Diverticulitis is a complex condition that often requires medical intervention, particularly in severe cases. Manuka honey can potentially serve as a complementary treatment, supporting infection control and gut health, but it should not replace prescribed antibiotics, dietary changes, or other treatments recommended by your healthcare provider.
Conclusion: A Promising Complementary Treatment
Manuka honey may offer benefits in managing diverticulitis symptoms due to its antibacterial and prebiotic properties. Although research suggests that it can reduce the presence of harmful bacteria like C. difficile and support the growth of beneficial gut bacteria, much of the evidence comes from laboratory studies rather than clinical trials involving people with diverticulitis. Its potential to work alongside antibiotics could make it a valuable addition to treatment plans, especially given the growing issue of antibiotic resistance.
However, it’s important to approach these findings with caution. Diverticulitis is a serious condition, and while Manuka honey may help manage symptoms or reduce the risk of infection, it should always be used under medical supervision and in conjunction with conventional treatments.
