What Is Bromelain? Other Names: Bromelaine, Bromelainum, Pineapple Enzyme

What is Bromelain?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Bromelain is a group of proteolytic enzymes predominantly found in the pineapple plant (Ananas comosus). It has garnered significant attention due to its wide range of therapeutic properties, including anti-inflammatory, immunomodulatory, antioxidant, and anticancer effects. This article delves into the various aspects of bromelain, from its sources and mechanisms of action to its potential applications in medicine. Other names include: Bromelaine, Bromélaïne, Bromelains, Bromelainum, Bromelin, Bromelina, Broméline, Enzyme d’Ananas, Pineapple Enzyme, Pineapple Fruit Bromelain.

Sources of Bromelain

Bromelain is derived from various parts of the pineapple plant, including the fruit, stem, leaves, and peel. The term “bromelain” originally referred specifically to the enzyme extracted from the stem, but it now encompasses the enzymes found in other parts of the plant as well3 9. The extraction and purification processes for bromelain have evolved over time, with modern techniques such as gel filtration, ion exchange chromatography, and recombinant DNA technology enhancing its production and purity10.

Therapeutic Applications of Bromelain

Anti-Inflammatory and Antioxidant Effects

Bromelain has been shown to reduce inflammation and oxidative stress in various conditions. For instance, it significantly alleviates the symptoms of periodontitis by reducing oral inflammatory parameters and improving hepatic steatosis4. It also mitigates oxidative stress and nephrotoxicity induced by aluminum chloride in rats, highlighting its potential as a nephroprotective agent7.

Anticancer Properties

Bromelain’s anticancer effects are well-documented. It induces apoptosis, inhibits angiogenesis, and enhances the immune response against cancer cells. Studies have shown that bromelain can be effective against various types of cancer, including breast, lung, and colon cancers1 8. However, more clinical studies are needed to validate its efficacy in human cancer treatment1.

Cardiovascular and Antidiabetic Benefits

Bromelain has shown promise in treating cardiovascular diseases by improving blood coagulation and fibrinolysis. It also exhibits antidiabetic properties by enhancing glucose metabolism and reducing insulin resistance. In a study on STZ-induced diabetic rats, bromelain significantly decreased fasting blood glucose levels and improved wound healing5.

Potential in COVID-19 Treatment

Recent research suggests that bromelain could be a complementary therapy for COVID-19 and post-COVID-19 patients due to its antiviral, anti-inflammatory, and cardioprotective properties2. Its ability to modulate the immune response and reduce inflammation could help in managing the symptoms and complications associated with COVID-19.

Bromelain Mechanisms of Action

Bromelain exhibits its therapeutic effects through multiple mechanisms. It modulates the arachidonate cascade, inhibits platelet aggregation, and interferes with malignant cell growth. Additionally, it has fibrinolytic activity, which helps in the breakdown of blood clots, and skin debridement properties, which aid in wound healing3 7. Bromelain’s anti-inflammatory action is particularly noteworthy, as it reduces the levels of pro-inflammatory cytokines and enzymes such as NF-κB, IL-1β, IL-6, and TNF-α6.

Adverse Effects of Bromelain

Gastrointestinal Issues

Bromelain can cause mild gastrointestinal disturbances such as nausea, vomiting, and diarrhea. These effects are generally mild and transient5 6.

Allergic Reactions

Some individuals may experience allergic reactions to bromelain, including skin rashes, itching, and difficulty breathing. These reactions are rare but can be severe in sensitive individuals5 6.

Increased Bleeding Risk

Bromelain has anticoagulant properties, which can increase the risk of bleeding, especially in individuals taking blood-thinning medications or those with bleeding disorders5 6.

Interaction with Medications

Bromelain may interact with certain medications, such as antibiotics and anticoagulants, potentially altering their effects. It is important to consult a healthcare provider before combining bromelain with other treatments5 6.

How has Bromelain Improved Patient Outcomes?

Pain and Swelling Reduction

Postoperative Pain and Swelling: Bromelain significantly reduces postoperative pain and swelling in patients undergoing mandibular third molar surgery, with effects comparable to diclofenac sodium1 6. It also shows a trend towards less inflammation and improved oral aperture post-surgery, although not statistically significant3.

Knee Osteoarthritis: Bromelain effectively reduces symptoms of knee osteoarthritis, including pain, stiffness, and physical function, with improvements observed in both short-term (4 weeks) and long-term (16 weeks) treatments2 4. It also shows a dose-dependent improvement in well-being and reduction in symptoms in otherwise healthy adults with mild knee pain4.

Quality of Life Improvements

Mandibular Surgery: Patients treated with bromelain report significant improvements in quality of life measures post-surgery, similar to those treated with diclofenac1.

Hematologic Tumors: In patients with hematologic tumors undergoing third molar extraction during chemotherapy, bromelain improves quality of life by reducing pain, swelling, and limited mouth opening, and by enhancing tissue repair pathways8.

Wound Healing

Gingival Grafting: Bromelain significantly reduces pain at the donor site following free gingival grafting and may enhance wound healing without increasing the risk of postoperative bleeding5.

Firearm Wounds: Topical bromelain accelerates wound healing by improving blood perfusion, oxygenation, and controlling inflammatory responses in firearm wounds10.

COVID-19

Mild to Moderate COVID-19: Bromelain improves clinical symptoms such as respiratory parameters and certain biochemical markers in hospitalized COVID-19 patients, suggesting potential benefits in managing the disease7.

Common Complaints Associated with Bromelain Use

Gastrointestinal Issues

Bromelain can cause gastrointestinal discomfort, including nausea, vomiting, and diarrhea. These symptoms are often mild but can be bothersome for some users.

Allergic Reactions

Some individuals may experience allergic reactions to bromelain, particularly those with allergies to pineapples. Symptoms can include itching, rash, difficulty breathing, and swelling of the mouth or throat.

Increased Bleeding Risk

Bromelain has anticoagulant properties, which can increase the risk of bleeding, especially in individuals taking blood-thinning medications or those with bleeding disorders.

Interactions with Medications

Bromelain can interact with certain medications, such as antibiotics and anticoagulants, potentially altering their effectiveness or increasing the risk of side effects.
