Due to its similarity to the actual grains such as wheat, it is often used in bread and pasta. Buckwheat tea is produced from the seeds of the plant. Its taste is light and subtle, it is drunk for enjoyment apart from health purposes. Some studies suggest that it aids in weight loss, provides nutrition, improves the health of the blood vessels, and reduces blood cholesterol. The preliminary research on Buckwheat tea is promising and suggests that the nutrients and chemicals in the tea can serve as a nutritional supplement.

Buckwheat Tea Benefits

Following are the incredible health benefits of buckwheat tea:

1. May Treat And Prevent Edema

According to a study published in the European Journal of Pharmacology, Buckwheat tea is highly effective in treating the edema swelling caused due to Chronic Venous Insufficiency (2). The study was carried out on human patients in whom one group was given the buckwheat tea while the other patients received placebo tea. The researchers noted a considerable improvement in the patients who received the Buckwheat tea than the patients in the other group. The study says that the tea was safe and had favorably influenced the edema patients with the CVI problem and can prevent its further progress.

2. May Have Significant Cardiovascular Benefits

Research suggests that increased intake of buckwheat may lower risk markers for cardiovascular diseases, such as glucose, total cholesterol and triglycerides (3), (4).

3. May Reduce Blood Glucose

A paper published in The Journal of Agricultural and Food chemistry states that Buckwheat tea or the concentrate reduced the level of blood glucose in diabetic rats (5). However, the process of preparation of Buckwheat tea or concentrates, in this case, is different from the regular method. Human studies have also linked buckwheat consumption with reduced risk of hyperglycemia, or high blood glucose (6).

4. May Improve Renal Function

Buckwheat concentrate, or the high-density tea, when given to rats inflicted intentionally with kidney damage showed significant improvement in the renal function and slowed down the kidney disease progression (7). However, the experiment is yet to be tried on human beings, but is expected to deliver similar results in people suffering from renal problems.

5. May Be Beneficial In Treating Diabetes

In a study, it was found that the ingredients present in the Buckwheat tea were beneficial in lowering blood sugar levels in diabetic mice. The rutin found in Buckwheat is extremely helpful in preventing type 2 diabetes when used with novel strategies. Another placebo-controlled studyi  XA method of testing a drug where one group receives the drug and the other group receives an inactive drug or placebo. has concluded that the Buckwheat seed extract or tea lowers the levels of blood glucose by 12 to 19% at 90 and 120 minutes after administration when given to laboratory animals with intentionally inflicted diabetes. On the other hand, the placebo group of animals did not show any glucose reduction (5).

According to a survey conducted on 58186 US adults about 9.7% (6317) were diagnosed with diabetes. While type 1 diabetes in the US population was 0.5%, type 2 diabetes affected more people about 8.5%. Type 1 diabetes was more prevalent among young adults belonging to the age group of 20 to 44 years and well-educated non-Hispanic people with low BMI. Type 2 diabetes on the other hand was higher among the elderly aged above 65 years, and non-Hispanic Asians with high BMI levels. With such a high prevalence of diabetes among the US population, the inclusion of foods that help control glucose levels is advised.

The scientists believe that the glucose lowering effect is caused due to the presence of a chiro-inositol compound that has been found to play a pivotal role in cell signaling and glucose metabolism in both animals and human beings. The researchers believe that the chiro-inositol may act as an insulin mimic and increase the sensitivity of the body cells to insulin.

6. May Improve Ovulatory Function

According to a human study published in the New England Journal of Medicine, buckwheat seeds and grains are loaded with D-Chiro-Inositol that increases the insulin actions in patients suffering from polycystic ovary syndrome. (8). Thus, it may contribute to improving the functioning of the ovulation, reducing blood pressure levels, decreasing the concentrations of serum androgen and plasma triglyceride.

It is rich in tocotrienolsi  XA type of chemical found in the Vitamin E family that promotes healthy brain function and has antioxidant properties. , vitamin E, flavonoids, minerals, phenolic acids, selenium, and phytic acid.
