Effect of chamomile on chemotherapy-induced neutropenia in pediatric leukemia patients: A randomized triple-blind placebo-controlled clinical trial

OBJECTIVE

Chemotherapy-induced neutropenia is one of the main side effects of acute lymphoblastic leukemia (ALL) treatment. In this trial, we evaluated the efficacy of chamomile in management of neutropenia.

MATERIALS AND METHODS

This randomized triple-blind placebo-controlled clinical trial was carried out in 2-18-year-old children with ALL. Participants in each group daily received 2.5 ml of either chamomile syrup or placebo syrup for a period of 30 days. Participants' white blood cell (WBC), and absolute neutrophil count (ANC), as well as their quality of life were evaluated.

RESULTS

The study was completed with a total of 40 patients. An increasing trend of ANC was observed in the treatment group despite the decreasing trend in placebo group, which was statistically significant between the two groups (P Interaction=0.019, 95% confidence intervals=15.076-171.324). No serious side effects were reported.

CONCLUSION

Using chamomile syrup as a complementary therapy in children with leukemia could improve their immunity (as it increased WBC) by minimizing chemotherapy-induced neutropenia.

A pilot randomized double-blind placebo-controlled trial on topical chamomile (Matricaria chamomilla L.) oil for severe carpal tunnel syndrome

OBJECTIVE

To assess the effectiveness of standardized topical Chamomile (Matricaria chamomilla L.) oil in patients with severe carpal tunnel syndrome, as a complementary treatment.

METHOD

A pilot randomized double-blind placebo-controlled trial was conducted. Twenty six patients with documented severe carpal tunnel syndrome were treated in two parallel groups with a night splint plus topical chamomile oil or placebo. They were instructed to use their prescribed oil for 4 weeks, twice daily. Symptomatic and functional status of the patients and their electrodiagnostic parameters were evaluated when enrolled and after the trial period, as our outcome measures.

RESULTS

A significant improvement of symptomatic and functional status of patients in the chamomile oil group was observed (p = 0.019 and 0.016, respectively) compared with those in the placebo group. However, electrodiagnostic parameters showed no significant changes between the two groups.

CONCLUSION

Chamomile oil improved symptomatic and functional status of patients with severe carpal tunnel syndrome.
