The medicinal value and health benefits of Stevia rebaudiana
Stevia rebaudiana (scientific name: Stevia rebaudiana), also known as "stevia leaves" or "sugar chrysanthemum", is a natural sweet plant with a sweetness 200-300 times that of sucrose, but almost no calories. In addition to being used as a sugar substitute, stevia also has various medicinal and health benefits, especially outstanding in regulating blood sugar, lowering blood pressure, and antioxidation.

1. Core medicinal value and scientific basis
(1) Natural zero calorie sugar substitute, suitable for diabetics
Sweet source: Stevioside, Rebaudioside A and other steviol glycosides, which do not participate in metabolism and do not affect blood sugar.

Research support: WHO (World Health Organization) and FDA approve its safety, and it is an ideal sucrose substitute, especially suitable for patients with diabetes and obesity.

(2) Regulate blood sugar and improve insulin sensitivity
Mechanism of action: Stevioside may promote insulin secretion by pancreatic beta cells and enhance peripheral tissue utilization of glucose.

Clinical evidence: some studies have shown that fasting blood glucose and postprandial blood glucose in patients with type 2 diabetes who take stevia extract have decreased (but the effect varies from person to person and cannot replace hypoglycemic drugs).

(3) Assist in lowering blood pressure
Vasodilatory effect: Stevioside can inhibit calcium ion channels, help relax vascular smooth muscle, and thus lower blood pressure.

Target audience: Mild hypertension patients can be used as an auxiliary conditioning method (blood pressure monitoring is required and cannot replace medication).

(4) Antioxidant&Anti inflammatory
Active ingredients: Stevia contains polyphenols and flavonoids (such as quercetin and kaempferol), which can scavenge free radicals and reduce oxidative stress.

Potential benefits: delay aging and reduce the risk of chronic inflammation (such as atherosclerosis).

(5) Protect the liver and regulate blood lipids
Animal experiment: Stevia extract can reduce liver fat accumulation and improve non-alcoholic fatty liver disease (NAFLD).

Regulating cholesterol: may reduce low-density lipoprotein (LDL, "bad cholesterol") and increase high-density lipoprotein (HDL).

(6) Antibacterial&Oral Health
Inhibition of bacteria: Stevioside has an inhibitory effect on Streptococcus mutans (a cariogenic bacterium) and can be used for natural oral care.

Sugar free anti decay: Stevioside does not cause tooth decay and is suitable for making sugar free chewing gum, toothpaste, etc.
