This randomized controlled clinical trial is designed to evaluate the efficacy and safety of Bosinji on low back pain and radiating pain of lumbar herniated intervertebral disc (L-HIVD) by assessing pain, function, and quality of life.

Seventy-four patients between the ages of 19 and 70 with L-HIVD will be recruited by eligibility criteria and randomly allocated to the experimental group and the control group. In the experimental group, 2.5g of Bosinji granule (Tsumura & Co., Tokyo, Japan) will be orally administered three times a day at 30 minutes after the meal for 6 weeks. In the control group, Loxonine tab. (loxoprofen 60mg, Dong Wha Pharm Co., Ltd, Seoul, Korea) will be orally administered in the same usage and period with the experimental group. In addition, both group will receive the same acupuncture treatment on 20 acupoints once a week for 6 weeks. 100 mm visual analogue scale (VAS) for low back pain will be assessed as a primary outcome at baseline and treatment end. Also, 100mm VAS for radiating pain, Oswestry disability index (ODI), Rolland Morris disability questionnaire (RMDQ), EQ-5D-5L and global perceived effect (GPE), Deficiency Syndrome of Kidney Index (DSKI) will be measured as secondary outcomes at baseline, 3 weeks after screening, treatment end (6 weeks, primary endpoint) and follow-up sessions (10 weeks).
