Drinking buckwheat tea does not cause internal heat. Buckwheat tea is not a traditional tea (green tea, black tea, floral tea, dark tea, white tea, etc.), but strictly speaking, it is a type of roasted grain tea. It is made by processing buckwheat seeds through steps such as screening and roasting. Modern clinical observations have shown that buckwheat flour and its products can help lower blood sugar and blood lipids, and enhance the body’s immune function. They have an auxiliary therapeutic effect on diabetes, hypertension, hyperlipidemia, coronary heart disease, stroke, and other conditions.
According to scientific research, buckwheat tea contains flavonoids, the main component of which is rutin. Rutin accounts for 70–90% of the total flavonoids. Rutin, also known as rutoside or vitamin P, can reduce capillary fragility and improve microcirculation. It is mainly used clinically as an auxiliary treatment for diabetes and hypertension. Rutin is almost absent in other grains.
Researchers have also studied the nutritional components of buckwheat and its anti-aging and health benefits. The results show that buckwheat tea is rich in protein, chlorophyll, fat, carbohydrates, crude fiber, minerals, and trace elements. It also contains 18 natural amino acids, with a total content of 11.82%, and 9 fatty acids. These promote growth and development in children and help prevent coronary heart disease in adults.
