Mulberry leaves are commonly known in
Vietnam,
particularly among those who raise silkworms for silk production. Beyond this, mulberry leaves have long been
used in traditional Eastern medicine for making beverages and treating ailments. What exactly are the benefits of mulberry
leaves? Let’s explore the eight health
benefits of mulberry leaves in this article!
Fresh
or dried mulberry leaves are frequently brewed into tea by Vietnamese people. These leaves contain numerous nutrients,
including free amino acids (phenylalanine, alanine, leucine, sarcosine, etc.),
proteins, vitamins (C, B1, D), and organic acids. With these nutrients,
mulberry leaves provide the following eight benefits:
1.
Blood Sugar Control
Mulberry leaves contain compounds that help lower
blood sugar levels and combat diabetes.
Among these, deoxynojirimycin (DNJ) is the most potent
glucose-lowering compound. DNJ, which has a similar structure to glucose,
blocks the absorption of starches and sugars—substances that contribute to high
blood sugar levels.
Additionally, DNJ helps reduce high blood sugar and
insulin levels, the hormone responsible for regulating blood sugar.
2. Lipid Reduction
Lipid metabolism disorders increase blood viscosity
and hinder blood flow through capillaries, potentially leading to blockages,
heart attacks, and strokes. Mulberry
leaves contain flavonoids, which reduce blood viscosity and enhance
capillary function. These compounds also improve lipid profiles, helping to
prevent strokes.
Extracts from mulberry leaves, rich in DNJ, quercetin,
and kaempferol, promote the oxidation of free fatty acids and lipids.
3.
Anti-Obesity Properties
Mulberry leaf extract reduces triglycerides,
significantly lowers the number of fat cells, and decreases the size of lipid
droplets in cells.
Moreover, prolonged consumption of mulberry leaves has
been shown to gradually increase circulat so I ing levels of adiponectin,
a cytokine that combats fat accumulation, reduces obesity, and inhibits the
maturation of fat cells.
4.
Blood Pressure Regulation
Mulberry leaves may help lower blood pressure by
inhibiting the production of angiotensin-converting enzyme (ACE), which regulates
blood pressure.
Research has found that mulberry leaf extract reduces
ACE activity by up to 95%, helping to lower blood pressure. While these studies have primarily been
conducted on animals, further research is needed to confirm these effects
in humans.
5.
Antioxidant Effects
Mulberry leaves are rich in flavonoid antioxidants,
which combat free radicals—compounds that increase cancer risk. Studies show that mulberry leaves reduce
inflammatory markers like C-reactive protein and oxidative stress markers like
superoxide dismutase.
Additionally, in vitro studies on human white blood
cells reveal that mulberry leaves reduce inflammatory proteins and
significantly mitigate DNA damage caused by oxidative stress.
6.
Atherosclerosis Prevention
Mulberry leaves contain polyphenols, flavonoids,
carbohydrates, proteins, and lipids that combat atherosclerosis. Regular use improves liver function, reduces
plaque burden, and lowers serum cholesterol, triglycerides, and low-density
lipoprotein (LDL) levels. The leaves also enhance endothelial function and
reduce arterial plaque.
7.
Cardiovascular Protection
In addition to preventing atherosclerosis, mulberry
leaf extracts improve heart health by lowering cholesterol and blood pressure. A study involving 23 individuals with high
cholesterol showed that after 12 weeks, LDL (bad cholesterol) decreased by
5.6%, while HDL (good cholesterol) increased by 19.7%.
8.
Improved Sleep
Mulberry leaf tea can help combat insomnia due to its
beneficial compounds, such as carotene, tannins, choline, trigonelline,
pentosan, calcium, and adenosine. These
active ingredients relax the body, reduce stress and fatigue, and promote
restful sleep.
Conclusion
These are the eight remarkable health benefits of
mulberry leaves. We hope this article helps you better understand their
advantages and inspires you to incorporate them into your lifestyle to protect
your health and that of your loved ones.
