Greek clover is an annual herb with aromatic seeds having medicinal properties. It is also known as fenugreek, and is largely used in curry. Greek clover has properties to lower down the levels of glucose in the body, which, in turn, controls diabetes. Also, when given in changeable doses of 25 gm to 100 gm on a daily basis, it was found to diminish reactive hyperglycemia in diabetic patients. Furthermore, levels of glucose, serum cholesterol, and triglycerides were also appreciably reduced. Alternatively, one can just stir two teaspoons of Greek clover seeds in powder form in warm milk and consume on a regular basis; it will control the levels of blood sugar and keep diabetes at bay. In case one does not want to have the powder in milk, seeds can be eaten wholly, too.
Several types of plants are referred to as ginseng, but most studies have used American ginseng. They've shown some sugar-lowering effects in fasting and after-meal blood sugar levels, as well as in A1c results (average blood sugar levels over a 3-month period). But we need larger and more long-term studies. Researchers also found that the amount of sugar-lowering compound in ginseng plants varies widely.
