Participants are randomly assigned in a 1:1 ratio to receive either Tri Thien Duoc pills or Diosmin (Daflon). Participants: A total of 172 participants with grade II internal hemorrhoids with bleeding were enrolled in the study and allocated as follows: Intervention Group: 86 participants received Tri Thien Duoc pills at a dosage of 8 capsules per day for 28 days, with follow-up conducted for 35 days from the initiation of treatment. Control Group: 86 participants received Diosmin (Daflon) at a dosage of 4 pills per day for 28 days, with follow-up conducted for 35 days from the initiation of treatment. Study Procedures: All participants in this Phase III study adhered to the dietary and lifestyle recommendations outlined by the American Gastroenterological Association for hemorrhoid management, including: Maintaining a high-fiber diet rich in vegetables and soft foods. Ensuring adequate hydration (1.5-2 litres of water per day). Engaging in regular physical activity. Avoiding prolonged sitting. Assessments and Monitoring: Participants underwent clinical evaluations and monitoring throughout the study. Key clinical parameters were assessed at four-time points: Baseline (Day 0, D0) Mid-treatment (Day 14, D14) End of treatment (Day 28, D28) Post-treatment follow-up (Day 35, D35) Laboratory tests, including liver and kidney function assessments, complete blood count, urinalysis, and colonoscopy, were conducted at baseline (D0) and treatment's end (D28).
