Anti-diabetic effect of dandelion leaves and roots in type two diabetic patients: A systematic review

Abstract

Purpose

The purpose of this paper was to synthesis all primary evidence relevant to the anti-diabetic effect of dandelion. Dandelion leaf and root have been used extensively for its medicinal and health benefits since hundreds of years ago. This systematic review was conducted to gather scientific evidence that are available with regards to the anti-diabetic effect of dandelion leaf and root.

Design/methodology/approach

A systematic search was conducted using PubMed, BioMed, PLUSONE and Cochrane databases between June 6, 2013 and June 30, 2013. Manual search was also done on books and journals in the KNUST library and its electronic database for possible documented effects of dandelion leaf or root on diabetic patients. Key words “dandelion”, “Taraxacum”, “dandelion and diabetes”, “Taraxacum officinale”, “Taraxacum and diabetes”, “dandelion and hypoglycemia” and “dandelion and hyperglycemia” were used in the search.

Findings

The search yielded 713 papers, and after the removal of duplicates and papers not relevant to this review, 20 papers were accepted for the review. These included studies conducted in humans and animals (rats and mice). Among the 20 studies reviewed, only 1 study examined and reported a positive hypoglycemic effect of dandelion on diabetic rats.

Research limitations/implications

The review only considered published papers and might have left out some unpublished research works.

Practical implications

The results of this review suggest paucity of data available on the use of dandelion in the treatment/management of diabetes. There is the need for well-designed clinical trials to ascertain the anti-diabetic effect of dandelion.

Social implications

The consumption of dandelion by type 2 diabetic patients to treat or manage their blood glucose has not been clinically proven to be effective, as shown by the review.

Originality/value

The paper provides a clear picture of the evidence available in the use of dandelion as an anti-diabetic herb, and this provides some preliminary data for the conduct of a clinical research on it.
