Buckwheat is divided into sweet buckwheat and bitter buckwheat. Tartary buckwheat (also known as bitter buckwheat) is produced in Inner Mongolia's Kulun, known as China's Buckwheat Hometown, and in the high-altitude plateaus of Yunnan, Guizhou, and Sichuan at 3,000 meters. It is rich in large amounts of rutin (also known as VP or rutoside) and niacin (vitamin PP), which are 13.5 times higher than in ordinary buckwheat. Rutin can maintain collagen levels in the body, beautify the skin, reduce fine wrinkles; promote stomach health and detoxification, helping with weight loss. It can also prevent "three highs" (hypertension, hyperlipidemia, hyperglycemia) in the elderly.
Main Nutritional Components of Buckwheat Tea
Rutin: Maintains capillary permeability, suitable for preventing and treating hyperlipidemia, hypertension, and diabetes.
Dietary Fiber: Helps prevent obesity, aids fat digestion, and has positive effects on hypertension, hyperlipidemia, and constipation.
Trace Elements: Increase essential elements in the body, protecting the liver and kidneys, aiding hematopoiesis, and boosting immunity. Also benefits intelligence, maintains cardiovascular health, and lowers cholesterol. For example, copper helps prevent nutritional anemia, and selenium helps prevent cancer.
Amino Acids: Especially cystine and cysteine, which have significant radioprotective effects.
Chlorophyll: Balances body nutrition and improves overall immunity.
Benefits of Buckwheat Tea
1. Prevents Gallstones and Lowers Cholesterol
The soluble fiber in Tartary buckwheat tea can also reduce bile accumulation to prevent gallstone formation. Consuming large amounts of dietary fiber lowers the risk of gallstones.
Dietary fiber, mainly composed of colloidal glucan, slows the rapid rise of glucose levels in the body after meals, effectively preventing diabetes.
Additionally, dietary fiber helps control cholesterol levels in the body.
2. Protects Capillaries, Lowers Blood Lipids, and Prevents Stroke
Prevents blood vessels from becoming fragile, especially capillaries. It also strengthens blood vessels, reducing the incidence of bruising, varicose veins, and hemorrhoids. It can also lower blood pressure and lipids, preventing stroke.
3. Prevents Diabetes Complications
Acts similarly to insulin, effectively lowering blood sugar. Tartary buckwheat can prevent or inhibit aldose reductase activity, helping delay or prevent diabetes complications.
4. Cleanses the Body and Aids Weight Loss
The soluble fiber content in Tartary buckwheat tea is much higher than in other cereals—4 times that of rice, 2.7 times that of wheat, 1.1 times that of corn, and 1.6 times that of sweet buckwheat.
Dietary fiber in bitter buckwheat promotes the excretion of toxic substances and lowers total serum cholesterol and LDL cholesterol levels.
Dietary fiber intake provides a feeling of fullness and slows digestion to reduce appetite, preventing overeating. Thus, it helps with weight loss.
How to Distinguish the Quality of Buckwheat Tea
Appearance: High-quality bitter buckwheat tea should have a yellow-green color, uniform size, and no color variation. Conversely, a whitish color or uneven shades indicate inferior quality. Pill-shaped tea is best because spherical shapes have the largest surface area, making it easier to release active components during brewing. Also, do not assume black buckwheat is named for its black shell—the inner part is still yellow-green. The market is flooded with inferior buckwheat products, which may suffer from sulfur fumigation, heavy metal超标, or bacterial超标. It is recommended to choose知名 brands like Chen Zhiqian Bitter Buckwheat Tea to avoid quality issues. Ordinary black buckwheat tea processed from buckwheat is tan-yellow, while whole-germ black buckwheat tea is slightly darker,呈棕褐色.
Taste: Good tea should retain the natural buckwheat aroma through processing本身, rather than using additives or chemical agents to create香味. High-quality bitter buckwheat tea has a pure buckwheat fragrance, while other types of scents or off-flavors indicate inferior quality. The production process involves roasting, which, when done适度, promotes the conversion of flavonoids in black buckwheat and increases rutin content. Top-quality black buckwheat tea has a fresh, wheat-like aroma but must not have a "burnt" taste, which indicates over-roasting and makes it unsuitable for consumption.
Raw Materials: Some buckwheat teas are made from bitter buckwheat, while others use black buckwheat. The active components in black buckwheat are 3–5 times higher than in ordinary bitter buckwheat. Therefore, "black buckwheat tea" made from black buckwheat is superior to "bitter buckwheat tea" made from ordinary buckwheat. Black buckwheat tea can be further categorized into whole-grain black buckwheat, bran black buckwheat, germ black buckwheat, and whole-plant black buckwheat. However, "rutin" and "selenium" are highest in the bran, while amino acids and dietary fiber are highest in the germ. Whole-plant tea uses discarded parts like the roots, stems, and leaves of buckwheat, which can easily rot if not processed及时 and are only available during harvest. Thus, black buckwheat tea made from bran and germ is of better quality.
