Ayurvedic practitioners treat diabetes with diet modification, Panchkarma, herbal preparations, yoga and breathing exercises. This review set out to identify all published evidence about the effectiveness of this approach to treatment.
In diabetes, does Ayurvedic medicine, as compared with usual care, improve glycemic control or quality of life?
The reviewers searched key bibliographic databases, including Medline, EMBASE, AMED and grey literature. They also hand searched a range of relevant journals.
They found seven studies, comprising 354 participants. These were evaluated and found to be of low methodological quality. They all focused on type 2 diabetes.
The trials showed evidence of effectiveness in improving glycemic control (reducing HbA1c and fasting blood glucose).
- Publication bias may be an issue with this review: negative trials may exist that have not have been published. There was not enough data for the reviewers to assess this statistically. However, the reviewers do state that “greater beneficial response was found in the pharmaceutical company funded studies of proprietary Ayurvedic drugs”, suggesting that publication bias was an issue.
- The studies used different preparations.
- Consider the types of patient that were included in the individual studies.
- There is not enough evidence here to rule in or rule out Ayurvedic. Larger trials are needed.
