The goal of this clinical trial is to evaluate whether holy basil extract can reduce gastric inflammation and improve symptoms in adult patients with dyspepsia.
The main questions it aims to answer are:
* Does holy basil extract reduce gastric mucosal inflammation as measured by histopathology?
* Does holy basil extract improve dyspeptic symptoms, endoscopic findings, gastric pH, duodenal eosinophil counts, and systemic inflammation (serum IL-6)?
Participants will:
* Take 300 mg of holy basil extract orally once daily for 28 days
* Complete symptom questionnaires and diaries during treatment
* Undergo upper endoscopy with biopsy and intragastric pH monitoring before and after treatment
* Provide blood samples for inflammatory marker measurement
* Be monitored for safety and adverse events
