Lavender improves fatigue symptoms in multiple sclerosis patients: A double-blind, randomized controlled trial.

BACKGROUND

Fatigue is one of the most common complications of Multiple Sclerosis (MS) patients. Several pharmacological and non-pharmacological interventions have been recommended to control this complication. Lavender is one of the plants considered by Persian Medicine (PM) and recommended by scholars of past centuries in the treatment of neurological diseases. This study aimed to investigate the efficacy of lavender capsule on improving fatigue symptoms in MS patients.

MATERIAL AND METHODS

In a double-blind, controlled trial, using a computer block randomization approach, 48 confirmed MS patients with eligibility criteria of being 18 years or older, Modified Fatigue Impact Scale (MFIS) ≥25, relapsing-remitting MS patients, EDSS ≤6, not pregnant, not breastfeeding, and not suffering from other diseases that cause fatigue, were randomized to receive capsules containing 600mg of lavender flowers as the intervention group or capsules containing 600mg cornstarch as the control group. Patients were randomized after completing the MFIS and were asked to take one capsule three times daily for 60 days. The MFIS again checked to assess the impact of two interventions. Analysis of Covariance (ANCOVA) was used to assess the impact of two interventions.

RESULTS

24 patients included in each group. The mean (standard deviation) of MFIS was 40.56 (7.63) in the intervention and 41.43 (7.89) in the control groups (p=0.706) before the intervention. However, there was a significant reduction (p0.001˂) in the intervention group, 7.04 (4.91) compared to the control group, 38.17 (9.78) after the intervention.

CONCLUSION

In comparison to cornstarch capsules, consuming the capsules of lavender flowers decreased the MFIS in MS patients.
