Promising pain-relieving activity of an ancient Persian remedy (mixture of white Lily in sesame oil) in patients with chronic low back pain

Abstract

Background and Objectives: Chronic low back pain (CLBP) is one the frequent musculoskeletal issues among adults mostly without a specific etiology. In this study, we investigated a traditional Persian remedy for back pain which is based on topical application of a mixture of sesame oil (SO) and white lily (LSM). Materials and Methods: The chemical profile, phenol content, and antioxidant activity of the herbal samples were determined using GC-MS, total phenol content (TPC) assay, and DPPH assay, respectively. Clinical efficacy of the herbal samples by a double-blind placebo was examined. Results: TPC of SO and LSM was 45 ± 5.7 and 68.3 ± 11.2 mg GAE/g oil mixture, respectively. The SO could inhibit 59.7% of free radicals, whereas LSM showed a radical inhibition rate of 74.7% in DPPH assay. LSM could reduce the pain feeling and obtained the lowest pain scores (Oswestry disability index and numeric rating scale) in weeks 4 and 8 of therapy in comparison to other treatment groups (diclofenac gel and SO) and placebo control (Vaseline). Conclusions: The results implicate the LSM as a novel therapeutic alternative for the therapy of the CLBP.
