OBJECTIVE: To evaluate the efficacy of topical chamomile oil in patients with mild and moderate carpal tunnel syndrome (CTS).
METHOD: Eighty six patients with electrodiagnostic criteria of mild and moderate CTS were enrolled in this randomized double-blind placebo-controlled clinical trial and received wrist splint plus topical chamomile oil or placebo for 4 weeks. They were evaluated at the baseline and end of the study regarding functional and symptomatic scores, dynamometry, and electrodiagnostic indexes.
RESULTS: Dynamometry, functionality, and symptom severity scores of the patients were significantly improved in the chamomile oil group compared with the placebo group (P = 0.040, P = 0.0001, P = 0.017, respectively). Additionally, compound latency of the median nerve in the chamomile oil group significantly decreased (P = 0.035) compared to the placebo group. Other electerodiagnostic measurements did not change significantly.
CONCLUSION: Complementary treatment with topical chamomile oil may have some benefits for patients with mild and moderate CTS, both subjectively and objectively.
