Introduction
Disorders of the gastrointestinal tract are among the most prevalent health concerns worldwide, significantly affecting quality of life and daily functioning. Symptoms such as bloating, indigestion, abdominal discomfort, constipation, diarrhea, and reflux are commonly reported across both developed and developing nations. Gastroesophageal reflux disease (GERD) represents one of the most important chronic upper gastrointestinal disorders, characterized by retrograde movement of gastric contents into the esophagus, leading to symptoms such as heartburn, acid regurgitation, and mucosal irritation. In severe or prolonged cases, GERD may progress to esophagitis, esophageal strictures, or Barrett’s esophagus, increasing long-term complication risk.
Modern management primarily includes proton pump inhibitors and H2-receptor antagonists; however, concerns regarding long-term safety, recurrence of symptoms, and patient compliance have encouraged exploration of plant-based alternatives. Medicinal plants containing bioactive compounds such as flavonoids, tannins, phenolics, and essential oils are increasingly recognized for their antioxidant, anti-inflammatory, mucosal protective, and mild acid-regulatory properties. In this context, a polyherbal powder formulation has been developed and evaluated for its potential anti-GERD activity.
Selection of herbal components and rationale
In a study, a polyherbal approach was adopted based on traditional usage and documented gastroprotective activity.
- Selected ingredients included ginger, turmeric, fennel, fenugreek, cumin, liquorice, amla, and bael fruit. These herbs are known to collectively support digestion, reduce gastric irritation, and strengthen mucosal defenses.
- Ginger and turmeric contribute anti-inflammatory and antioxidant effects, while fennel and cumin provide carminative and antispasmodic activity, reducing gas and abdominal discomfort. Fenugreek offers mucilaginous protection of the gastric lining, and liquorice is known for its mucoprotective and healing properties. Amla contributes potent antioxidant activity, while bael fruit supports bowel regulation and gastric stability.
- The formulation base was prepared using bael fruit powder, serving as a stabilizing and digestive-supporting matrix. The herbal ingredients were dried, powdered, sieved, and blended uniformly to ensure homogeneity.
Phytochemical evaluation and screening
Preliminary phytochemical screening confirmed the presence of key bioactive constituents across the formulation. Phenolic compounds were detected in ginger and fennel extracts, alkaloids were identified in turmeric and fenugreek, tannins were confirmed in amla and bael fruit, and flavonoid-related constituents were observed in liquorice. These compounds are known to contribute to antioxidant, anti-inflammatory, and gastroprotective activities relevant to GERD management.
Formulation development
Each 10 g of polyherbal powder contained standardized proportions of active ingredients, including ginger (0.6%), turmeric (0.2%), fennel (0.6%), fenugreek (1.8%), cumin (0.6%), liquorice (0.6%), amla (1.6%), and bael fruit powder (4.0%). The formulation was designed for oral administration with water, providing a simple, safe, and patient-friendly dosage form intended to reduce gastric irritation and improve digestive efficiency.
Physicochemical and powder evaluation
The developed formulation was assessed for organoleptic and physicochemical properties.
- The powder exhibited a pale-yellow color with a characteristic herbal odor and a slightly sweet taste. A uniform fine powder consistency was observed, indicating effective sieving and blending.
- The pH of the formulation was found to be 7.1, indicating near-neutral compatibility with gastric conditions. Flow properties were evaluated using angle of repose, bulk density, and tapped density measurements.
- Phytochemical profiling confirmed the presence of tannins, flavonoids, saponins, and phenolic compounds, all of which contribute to mucosal protection and reduction of oxidative stress in GERD.
Results and Safety Evaluation
Organoleptic evaluation confirmed acceptable appearance, odour, taste, and uniformity. No microbial contamination was observed during short-term stability assessment, supporting formulation safety. The synergistic interaction of herbal constituents was considered responsible for anti-inflammatory, antioxidant, and antibacterial effects, which collectively support esophageal mucosal protection and acid-related symptom reduction.
Conclusion
The developed polyherbal powder formulation demonstrated satisfactory physicochemical characteristics, stability, and phytochemical richness relevant to GERD management. The combined effects of selected medicinal plants were observed to support gastric protection, reduce irritation, and improve digestive balance. Based on evaluation findings, the formulation may be considered safe and potentially effective for oral use in GERD symptom management. However, extended stability studies and well-designed clinical trials are required to further validate therapeutic efficacy, optimize dosage, and establish long-term safety for clinical application.1
