N2 - Problem Statement: Increasing interest from the general public to use herbal remedies, exposes a considerable need to document ancient medical practices, as well as to investigate the efficacy of "ancient" compounds currently reputed to have medicinal benefits for such diseases as diabetes and obesity.Approach: In order to investigate the efficacy of "karkadeh" Roselle-Hibiscus sabdariffa tea as a means of reducing post-prandial blood glucose levels in human subjects, 10g of dried karkadeh was brewed in 500ml of water, allowed to infuse for 60 min and imbibed along with a high glycemic index food.Results: Data show that in one individual, karkadeh tea taken in connection with a carbohydrate based breakfast meal resulted in a significant increase (17%; p<0.01) in blood glucose level cf. an ordinary breakfast tea 60 min after ingestion. Moreover, in a study involving eight individuals, a slower rise to maximum levels and a greater Area Under the Curve (AUC) in terms of blood glucose was noted for the karkadeh tea plus a high glycemic index food cf. that of water imbibition with an identical high glycemic food.Conclusions/Recommendations: Karkadeh tea appears to have an efffect in terms of slowing the rate of rise in blood glucose following consumption of a high glycemic index food, but that ultimately it induces a greater degreee of glucose absorption cf. other types of imbibed fluids.
