Is honey an effective treatment for acute cough in children?
¿Es la miel un tratamiento efectivo para la tos en población pediátrica?
Abstract
Cough represents one of the most common reasons for pediatrician consultations. There are many available treatments for symptomatic relief, including honey. Despite its wide availability, there is little knowledge about its benefits. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including three randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded the use of honey probably decreases the severity and frequency of cough, improves the quality of parent's and patient's sleep, and does not have side effects.
Problem
Cough is a complex physiological event consisting of a violent expiration in order to release secretions, foreign material or bronchospasm airway driving and protect the respiratory system from chemical, infectious, mechanical and thermal agents. Acute cough lasts less than four to eight weeks (depending on the definition used). It is not a disease in itself but a symptom related to many respiratory diseases. Depending on the intensity and frequency of the cough, it often leads to a negative impact on the quality of life for both the child and his family, generating a high number of medical consultations.
It has been suggested that honey, due to its antioxidant properties and the release of cytokines, could be used as treatment.
Despite of being a widely available treatment, there is little information about its effects.
Methods
We used Epistemonikos database, which is maintained by screening more than 30 databases, to identify systematic reviews and their included primary studies. With this information we generated a structured summary using a pre-established format, which includes key messages, a summary of the body of evidence (presented as an evidence matrix in Epistemonikos), meta-analysis of the total of studies, a summary of findings table following the GRADE approach and a table of other considerations for decision-making.

Key messages

About the body of evidence for this question
|
What is the evidence. |
We found three systematic reviews [1],[2],[3] including three [4],[5],[6], randomized controlled trials. Another systematic review [7] was identified in the search, but without included trials, so it is not analyzed in this summary. |
|
What types of patients were included |
One study [4] included patients between 1 and 5 years. The second study [5] included patients between 2 and 18 years. The third study [6] included patients between 2 and 5 years. The three studies included patients with upper respiratory tract infections and nighttime cough of less than 7 days. |
|
What types of interventions were included |
All of the studies [4],[5],[6] evaluated a single dose of honey 30 minutes before sleep. One study compared against placebo [4] and the other two versus no treatment [5],[6]. |
|
What types of outcomes |
The outcomes analyzed were:

Summary of findings
The information about the effects of honey for the treatment of acute cough is based on three randomized trials [4], [5], [6] including 568 patients. All of the studies reported frequency and severity of cough, and parent’s and children’s quality of sleep. Only one study reported the side effects of honey versus placebo [4].
- Honey probably decreases the severity of cough. The certainty of the evidence is moderate.
- Honey probably decreases the frequency of cough. The certainty of the evidence is moderate.
- Honey probably allows patients to sleep better at night. The certainty of the evidence is moderate.
- Honey probably allows parents to sleep better at night. The certainty of the evidence is moderate.
- The use of honey probably leads to little or no difference in adverse effects, in comparison with placebo. The certainty of the evidence is moderate.

How we conducted this summary
Using automated and collaborative means, we compiled all the relevant evidence for the question of interest and we present it as a matrix of evidence.

Notes
The upper portion of the matrix of evidence will display a warning of “new evidence” if new systematic reviews are published after the publication of this summary. Even though the project considers the periodical update of these summaries, users are invited to comment in Medwave or to contact the authors through email if they find new evidence and the summary should be updated earlier. After creating an account in Epistemonikos, users will be able to save the matrixes and to receive automated notifications any time new evidence potentially relevant for the question appears.
