Edible Guizijiang, also known as Yangjiang and Chrysanthemum Ginger, is an edible root vegetable. Because of the poor taste, Chinese people seldom use it for cooking, but mostly for pickling pickles, which may be the reason why Yangjiang's "popularity" is not high.

In recent years, it has been found that ginger has a special effect-it has a two-way regulation effect on blood sugar, that is, on the one hand, it can reduce the blood sugar of diabetic patients, on the other hand, it can increase the blood sugar of hypoglycemia patients. Studies have shown that Alpinia officinarum contains a substance whose structure is very similar to insulin produced by human pancreas. When urine sugar appears, eating Alpinia officinarum can control urine sugar, which shows that Alpinia officinarum has the effect of lowering blood sugar. However, when people's pancreatic function is abnormal and hypoglycemia occurs, taking ginger can raise blood sugar and stabilize blood sugar.

So both hyperglycemia and hypoglycemia can be treated with ginger.

Ginger has the function of regulating blood sugar in both directions, which is rare among other vegetables.
