Anti-inflammatory and Antioxidative Potential of Herbs and Fruits in the Management of Inflammatory Bowel Disease Beyond Medications

Inflammatory Bowel Disease (IBD), a chronic inflammatory condition of the gastrointestinal tract, primarily encompasses ulcerative colitis and Crohn's disease. Characterized by recurring inflammation, IBD is marked by its unpredictability and complexity. Crohn's disease may impact any part of the digestive system, causing significant ulcerations, whereas ulcerative colitis is mainly restricted to the colon, leading to persistent damage and ulcers. The intermittent nature of IBD, alternating between remission and active flare-ups, presents continuous challenges in patient care and treatment. Its etiology is multifaceted, involving a combination of genetic susceptibility, environmental triggers, and immune system malfunctions. Symptomatically diverse, IBD can manifest as abdominal discomfort, diarrhea, weight loss, and fatigue, complicating the establishment of uniform treatment protocols. Traditional pharmacological treatments often offer limited relief and may introduce side effects, necessitating frequent adjustments in therapy. This disease profoundly impacts not only the physical well-being of individuals but also their overall quality of life, calling for a comprehensive and individualized management approach. This review delves into the potential of herbs and fruits in IBD management, examining their proximate composition and the roles their anti-inflammatory and antioxidant properties play in enhancing gut health


INTRODUCTION
Inflammatory Bowel Disease (IBD) is a complex and chronic group of inflammatory disorders that predominantly affect the gastrointestinal tract, encompassing two major forms: ulcerative colitis and Crohn's disease (1).Characterized by persistent inflammation, IBD manifests in symptoms such as diarrhea, abdominal pain, fatigue, and weight loss (2).The pathogenesis of IBD is understood to be an inadequate immune response to gut microbiota in genetically predisposed individuals, although its exact etiology remains elusive (3).Crohn's disease, distinct in its ability to affect any segment of the gastrointestinal tract, often leads to deep ulcerations and complications like strictures or fistulas (4).Conversely, ulcerative colitis is restricted to the colon, causing continuous inflammation and ulcer formation there (5).The chronic and relapsing nature of IBD presents considerable management challenges, aiming for symptom control and prevention of complications.Conventional medications have played a significant role in managing IBD, but not without their drawbacks (6).Long-term pharmacological treatments often lead to a range of side effects, from minor discomforts to severe complications.Corticosteroids, commonly prescribed for their anti-inflammatory effects, may lead to mood swings, hyperlipidemia, gastrointestinal and hepatic disorders, weight gain, hyperglycemia, diabetes, and an increased susceptibility to infections (7).Additionally, prolonged use of certain medications can lead to drug resistance, prompting the exploration of alternative management approaches for IBD (8).In light of the limitations of traditional medications, the use of herbs and fruits has emerged as a promising alternative approach in managing IBD (8).These natural sources are rich in bioactive compounds like antioxidants and anti-inflammatory agents, offering therapeutic benefits without the side effects commonly associated with pharmaceutical interventions (9).The natural and holistic properties of herbs and fruits, including pomegranate, strawberries, pineapple, kiwi, turmeric, ginger, amla, and mint, contribute significantly to their therapeutic potential.These substances are particularly effective in neutralizing oxidative stress, a key factor in exacerbating inflammation in IBD (12)(13)(14)(15)(16). Thus, incorporating these organic interventions into IBD management strategies presents a viable, complementary approach to conventional treatments, emphasizing their role in enhancing overall patient well-being and quality of life.
