According to Chinese legend, Empress His Ling Shi in the 27th century BC was sipping tea under a mulberry tree when a cocoon fell into her cup. The Empress tried to pull the cocoon out of her tea but found that only a thin strand slowly unwound itself from the cocoon. In amazement, she had discovered the very strong fiber known as silk. From that time on, silken garments became popular throughout Asia. There are records of the cultivation of mulberry tress in China dating back 3,000 years when the ancient Chinese used the mulberry tree for raising silkworms, papermaking, food, and the leaf was brewed as tea for its medicinal qualities.

The dried leaf used as tea or in soup was used to expel wind and clear heat, reduce liver inflammation, and improve vision. Other uses in TCM include relieving cough and cold symptoms, curing dizziness, strengthening the eyes, promoting healthy blood, curing dysentery, treating stomachache, supporting liver function, and sustaining youthful skin.

Mulberry Leaf for Diabetes

         Meanwhile, in Japan, records showed that mulberry leaf was used to treat diabetes. The Central Institute of Silkworm Industry in Japan developed the mulberry tea for health care, due to its content rich in protein, minerals, and vitamins. When drunk, the Japanese noted that it is a very convenient way to quickly absorb nutritive elements, along with promoting metabolism and removing fatigue. In Japan today, there are still many products which incorporate mulberry leaf, including rice noodles, sweet cake buckwheat noodles.

Mulberry Tea and Infections

         According to modern research, it helps to clear fever, headache, sore throat, cough, and red or painful eyes. Mulberry tea can also inhibit the development of bacterial strains, including streptococcus, the cause of strep throat. Asians drink mulberry tea to prevent and recover from common cold symptoms.

Mulberry Leaf and Carbs

         Mulberry tea naturally inhibits carbohydrate absorption. This is a
result of the compound moranoline (1-deoxynojirimycin). Moranoline inhibits an enzyme in the intestinal tract (alpha-glucosidase) involved in the digestion of carbohydrates. This means the starchy, carbohydrate-rich foods you eat, like bread, rice, pasta and potatoes, do not turn to glucose in your body and are simply flushed out. The lack of glucose in your system lowers your blood sugar levels, making you less hungry. Used as
part of a sensible diet, mulberry tea helps improve weight loss.

Mulberry Leaf and Circulation

         Mulberry tea reduces the oxidization of cholesterol in the blood vessels, resulting in reduced risk of atherosclerosis (blocked blood vessels). This is due to quercetin and additional flavonoids contained in
mulberry leaves. These antioxidants inhibit oxidative stress reactions that produce atherosclerosis. For healthy blood vessels, drink mulberry tea as a regular supplement to a healthy lifestyle.

Mulberry Leaf and Blood Sugar

         Mulberry leaf tea can balance blood sugar and aids in carbohydrate absorption according to a 2008 study. According to Medical News Today, the herb lowers post-meal blood sugar spikes and stabilizes blood sugar levels. As a result, drinking mulberry tea results in more sustained energy levels throughout the day.

For centuries, mulberry tea has been used as a treatment for diabetes mellitus in Asia. One of the most unique qualities of the mulberry leaf tea is its ability to prevent sugars from entering your bloodstream. Researchers in Japan found that mulberry leaves contain compounds that inhibit intestinal enzymes from passing sugars into the bloodstream. This inhibitor compound known as 1-deoxynojirimycin (DNJ), can only be extracted from the mulberry leaf. By preventing large amounts of monosaccharide from entering into circulation, mulberry tea helps prevent and fight diabetes. Persons using prescription drugs to treat pre-diabetes should monitor blood sugar by consulting their health care provider.

Medication Interactions

Those who are already taking medications for diabetes should avoid the mulberry tea. The medication may interact with the mulberry tea to increase the chances of low blood sugar or hypoglycemia.

Allergic Reactions

Kidney Effects

Kidney disease patients may feel discomfort when drinking mulberry leaf tea due to its high presence of potassium. So it would be better to avoid the mulberry tea by kidney patients.


Those who are breast feeding, pregnant or are undergoing surgery within the next two weeks should avoid drinking the mulberry tea.

Side effects are possible with higher doses and may include mild diarrhea, dizziness, constipation, and bloating. Because of its effect on blood glucose, white mulberry should be used with guidance in people on diabetic medications, including insulin.
