It is an approved commercial product in China, specifically listed as an exclusive formulation by the company. The medication is intended for oral administration to treat gastrointestinal conditions. As a traditional herbal product, its therapeutic effects are attributed to the synergistic action of its constituent herbs according to TCM principles, rather than a single defined molecular target.
