Effects of Glucoscare Tea

In herbal management, the geographic location, age, season of harvest and the active components of the herbs all play an important role in yielding the best results. Glucoscare tea is recommended by the Polish Diabetic Society, which states that it is a ‘natural way to reduce the blood sugar level for diabetics and people who do not tolerate glucose.

How is Glucoscare herbal tea beneficial in Type 2 Diabetes?

Comprising of a blend of different herbs with major constituents being green tea (camellia sinesis) and Gymnema herb, Glucoscare tea has been scientifically proven to be useful in diabetes as it has two-fold benefit of increasing the secretion of insulin (a regulatory hormone which helps to reduce excess sugar in blood) and reducing sugar absorption thereby proving itself useful for the weight-conscious.

It has been found in a study conducted by King’s College, London, that Gymnema extracts consisting of gymnemic acids have stimulatory effects on insulin release by increasing cell permeability, rather than by stimulating exocytosis by regulated pathways.

Using about 500 rat islets of Langerhans, the experiment showed that the extract (standardised Gymnema GS4) had stimulatory effects that differed from those of other insulin secretagogues as it was able to stimulate insulin release at temperatures as low as 4˚C, whereas regulated physiological insulin secretion only occurs at temperatures in excess of 30˚C.

A study was conducted by the University of Sydney, the University of Queensland and the German institute for Physical Biology showed that a polypeptide extracted from Gymnema leaf, Gurmarin, has been found to selective inhibit the neural response to sweet-taste stimuli in rats such as glucose, sucrose, glycine and saccharine without affecting responses to other taste stimuli including the taste of salty, sour or bitter items.

This may lead to patients avoiding food that contains sugar, thus lowering the chances of exceeding their daily restricted sugar intake.

A toxicity test on 40 rats was conducted by SGS Healthcare and Pharmaceutical Services, in Hong Kong. There was no death or moribundity (lack of vitality) that occurred in Glucoscare Tea- treated mice after a single dose of 250g/kg body weight (equivalent to 3000 times the recommended human daily dose) was orally administered. It was concluded that it exerted no adverse toxic effect.

A randomised non-blind open label clinical study was also conducted for 3 months in the Department of Dietetics and Department of Endocrinology, Osmania General Hospital, Hyderabad. The study was on the effect of Glucoscare Heabal Tea (prepared from the standardized extract derived from Gymnema leaf blended with green tea) in the control of hyperglycemia and its associated complications in primary care Type 2 Diabetes Mellitus.

However, more studies need to be done and it has to be documented closely in these patients over a long time with the estimation of insulin levels.


The study concluded that there is/are:

  • No adverse effects.
  • No side effects even on using long-term.
  • Hope of generation of Beta Cells (indirect evidence).
  • Possibility of arrest of further destruction of residual Beta cell function.
  • Improvement in blood sugar values (both fasting and post-lunch).
  • Improvement in Lipid parameters, glycosylated haemoglobin (HbAlc) levels and reversal of microalbimininuria.
  • Beneficial effects on weight control.
  • Improved glucose uptake by peripheral tissue.
  • Persistent hypoglycemic effects which are not observed on withdrawal of tea.
