Effect of guava leaf extract in combination with acarbose or voglibose on increased blood glucose level in sugar-loaded normal mice. According to an article published in Nutrition and Metabolism, guava leaf tea inhibits several different enzymes that convert carbohydrates in the digestive tract into glucose, potentially slowing its uptake into your blood. Study on the hypoglycemic activity of different extracts of wild Psidium guajava leaves in Panzhihua Area. Moreover, GvEx did not induce chromosomal aberrations in a micronuclear test using peripheral blood erythrocytes, which were prepared from mice by a single oral administration of GvEx (2000 mg/kg).

In addition, the improvement of diabetes symptoms, such as hyperglycemia, nephropathy (Table ​ (Table1) 1) and insulin resistance, has been reported with the consecutive ingestion of GvEx in diabetic animal models [ 15]. Several test-tube and animal studies found that guava leaf extract improved blood sugar levels, long-term blood sugar control, and insulin resistance ( 1, 2, 3, 4, 5). This review describes the active component of the aqueous guava leaf extract and its inhibition of alpha-glucosidase enzymes in vitro, safety of the extract and Guava Leaf Tea, reduction of postprandial blood glucose elevation, and improvement of hyperglycemia, hyperinsulinemia, hypoadiponectinemia, hypertriglycemia and hypercholesterolemia in murine models and several clinical trials.Effects of an alpha-glucosidase inhibitor, acarbose, on blood glucose and serum lipids in streptozotocin-induced diabetic rats. In particular, the enrolment of patients who received anti-hypertensive drugs and other commercial drugs is important to obtain more information on the absence of interaction between Guava Leaf Tea and these drugs. Guava leaf tea comes from a small tree in the myrtle family, the same tree that grows pink guava fruit.

Renew the image of guava tea that is hard to drink, and it has an appearance that stimulates willingness to drink, and can provide guava tea in an unprecedented form. It is suggested that the chronic suppression of postprandial blood glucose elevation is important in preventing type 2 diabetes mellitus, and that Guava Leaf Tea is considered useful as an alimentotherapy for chronic treatment. To determine the effect of GvEx on postprandial blood glucose elevation, normal mice were immediately given GvEx or saline (control) following overnight fasting. Voglibose for prevention of type 2 diabetes mellitus: a randomised, double-blind trial in Japanese individuals with impaired glucose tolerance.

According to a third aspect of the present invention, the guava tea leaf production method is characterized in that after twisting is performed to such an extent that the fibers are not cut, the leaves are opened and shaped, and then dried for eight minutes. The re-drying process is to dry the wrapped guava tea leaves in the same shape, and any suitable drying means such as natural drying, hot air drying, low temperature drying, and freeze drying can be used. Most people choose to drink guava leaf tea for its high vitamin C content and antioxidant properties. In contrast, there were no significant effects on weight gain, food and water intakes of the diabetic mice. Treatment with thiazolidine derivatives, one type of anti-diabetic drugs, ameliorates insulin resistance and increases serum adiponectin level in T2DM patients with hypoadiponectinemia [ 5].
