Lignin in Treatment of Helicobacter Pylori Infection

The goal of this clinical trial is to learn if drug hydrolyzed lignin works to treat H pylori infection in adults. It will also learn about the safety of drug lignin n the sitting of H pylori infection, and if it halts the side effects associated with H pylori triple therapy. The main questions it aims to answer are: * Does drug hydrolyzed lignin improve the H pylori eradiation rate when it is added to the standard triple therapy used in treatment of H pylori? * What medical problems do participants experience when taking drug hydrolyzed lignin? Researchers will compare drug hydrolyzed lignin to a placebo (a look-alike substance that contains no drug) to see if drug hydrolyzed lignin works to treat H pylori. Participants will: * Take drug hydrolyzed lignin or a placebo every day for 2 weeks beside the standard triple therapy * Visit the clinic once every 1 week for checkup and questionnaire filling * Check for H pylori eradication after treatment
