Clinical research on the effectiveness and safety of Uchasingihwan for low back pain with radiculopathy caused by herniated intervertebral disc of the lumbar spine: A multicenter, randomized, controlled equivalence trial.

If you've ever dealt with a herniated disc in your lower back, you know how debilitating the combination of back pain and shooting leg pain can be. Researchers in a recent clinical trial explored whether a traditional herbal medicine formula could work just as well as a common pain reliever — and the results are encouraging for those seeking natural treatment options.

The study focused on a traditional Korean herbal formula called Uchasingihwan (UCSGH), which has been used historically for musculoskeletal conditions. Researchers wanted to find out if this herbal granule could match the effectiveness of loxoprofen, a widely used anti-inflammatory pain medication, for people suffering from lumbar disc herniation with radiating nerve pain (radiculopathy).

Seventy-four participants were divided into two groups. One group took the herbal formula three times daily, while the other took loxoprofen three times daily. Importantly, both groups also received weekly acupuncture treatments for six weeks. Patients were assessed at the start of the study and again at 3, 6, and 10 weeks.

The findings were striking: the herbal formula performed equivalently to the pharmaceutical drug in reducing both low back pain and radiating leg pain at the six- and ten-week marks. Improvements in physical function and quality of life were also similar between the two groups. Perhaps most notably, patients taking the herbal formula experienced fewer adverse side effects compared to those taking loxoprofen.

For patients exploring integrative approaches to disc-related back pain, this study suggests that combining acupuncture with herbal medicine may offer a viable, gentler alternative to conventional pain medications — without sacrificing effectiveness.

If you're considering this type of treatment, speak with a licensed acupuncturist or Traditional Chinese Medicine practitioner who is qualified to recommend and oversee herbal medicine protocols.

This multicenter, randomized, controlled equivalence trial (NCT03386149) evaluated Uchasingihwan (UCSGH), a traditional Korean herbal granule, against loxoprofen 60 mg for lumbar herniated intervertebral disc (LHIVD) with radiculopathy. Seventy-four participants were randomized to receive either UCSGH 2.5 g TID or loxoprofen 60 mg TID for six weeks, with both arms receiving standardized acupuncture once weekly. Primary outcomes measured VAS changes for low back and radiating pain at weeks 6 and 10. Mean differences fell within the pre-specified equivalence margins at both timepoints for low back pain (95% CI: −9.26 to 8.37 at week 6; −9.03 to 9.62 at week 10) and radiating pain (95% CI: −1.70 to 15.69 at week 6; −4.72 to 13.75 at week 10). Secondary outcomes including functional indices and quality-of-life measures showed no statistically significant between-group differences. Notably, the incidence of intervention-related adverse events was lower in the UCSGH group. Clinical takeaway: UCSGH combined with acupuncture represents a clinically equivalent and potentially safer alternative to NSAID therapy for LHIVD management.
