This clinical study aimed to assess the effectiveness and safety of Vuong Hoat (VH) natural health supplement for reducing the negative impact of low back pain, improving the quality of life, and enhancing functional activities in patients with lumbar degenerative disc disease (LDD). The open-label, randomized, controlled clinical trial involved 60 patients suffering from low back pain caused by LDD. The participants were randomly assigned to either a study group (SG) comprising 30 subjects or a control group (CG) comprising 30 subjects. Patients in the CG received treatment with electro-acupuncture, while those in the SG were administered VH in conjunction with the same electro-acupuncture protocol for 28 days. The clinical progression and tolerability of both groups were compared based on seven objective measurements: visual analog scale index, Schober test, fingertip-to-floor distance, spinal flexion, spinal extension, spinal tilt, and spinal rotation. After 14 days of treatment, the SG showed a significant improvement in overall outcomes compared to the CG. Specifically, 43.3% of SG patients achieved very good results, 53.3% had good results, and 3.4% had moderate results, whereas corresponding figures for the CG were 6.7%, 76.7%, and 16.6%, respectively (
