In a similar case-report study, involving 12 patients with newly diagnosed
type II diabetes, the effect of the crude drug on blood glucose levels
was assessed. Each patient received one of two crude drug preparations.
The first was an aqueous extract prepared by boiling 100 g of the crude
drug in 200 ml of water until the volume was reduced to 100 ml. The second
preparation was dried fruit powder, administered at a dose of 5 g
three times daily. After 3 weeks of treatment the group using the powder
preparation showed a reduced post-prandial blood glucose level of 25%,
but the result was not statistically significant. However, in the group receiving
the aqueous extract, a significant reduction (54%, p < 0.01) in
blood glucose was observed, as well as a reduction in glycosylated haemoglobin
from 8.37% to 6.95% (p < 0.01) (30).
