Generally, the benefits and effects of mulberry leaf tea include lowering blood glucose, clearing liver heat and improving vision, promoting weight loss and reducing lipids, antioxidant activity, and diuretic and anti-edema effects. Contraindications typically include caution for individuals with cold body constitution, pregnant and breastfeeding women, those allergic to mulberry leaves, controlled intake quantity, and avoiding consumption on an empty stomach. If discomfort occurs after drinking, it is recommended to seek medical attention promptly and receive treatment under a doctor's guidance. Specific analysis is as follows:

I. Benefits and Effects

1. Lowering Blood Glucose

Mulberry leaves contain 1-deoxynojirimycin (DNJ), which can inhibit intestinal absorption of sugar, thereby reducing postprandial blood glucose levels. Additionally, mulberry leaves contain various amino acids and trace elements that help improve insulin sensitivity, offering certain auxiliary therapeutic benefits for diabetic patients.

2. Clearing Liver Heat and Improving Vision

Mulberry leaves are rich in vitamin A and beta-carotene, both of which benefit eye health by promoting retinal cell regeneration and preventing night blindness and vision deterioration. Meanwhile, mulberry leaves have heat-clearing and detoxifying properties, helping the liver eliminate toxins, reducing hepatic burden, protecting vision, and supporting liver health.

3. Weight Loss and Lipid Reduction

The DNJ component in mulberry leaves not only lowers blood glucose but also reduces fat accumulation in the body, exerting positive effects on individuals with obesity or hyperlipidemia. Furthermore, flavonoids in mulberry leaf tea accelerate fat breakdown and metabolism, aiding in weight management and obesity control.

4. Antioxidant and Anti-Aging

Mulberry leaf tea is rich in antioxidants such as catechins, flavonoids, and polyphenolic compounds, which neutralize free radicals in the body, prevent cellular aging, and delay the aging process. Long-term consumption helps maintain skin elasticity and luster, preventing age spots and wrinkles.

5. Diuretic and Reducing Edema

Mulberry leaves have notable diuretic properties, promoting the elimination of excess fluid from the body and alleviating edema. For swelling caused by excessive fluid retention or mild hypertension, mulberry leaf tea may provide some relief.

II. Contraindications

1. Caution for Individuals with Cold Body Constitution

Mulberry leaf tea is cooling in nature; prolonged and excessive consumption may increase internal coldness, leading to symptoms such as cold hands and feet or diarrhea. Individuals with a cold constitution, especially those with spleen and stomach deficiency-cold, should avoid excessive consumption to prevent worsening of cold-related symptoms.

2. Caution for Pregnant and Breastfeeding Women

Certain components in mulberry leaf tea may adversely affect the fetus or infant. Notably, mulberry leaf tea may stimulate uterine activity, potentially increasing the risk of miscarriage in pregnant women.

3. Prohibited for Those Allergic to Mulberry Leaves

Individuals allergic to mulberry leaves must strictly avoid consuming mulberry leaf tea to prevent allergic reactions, which may include symptoms such as skin itching and difficulty breathing, posing risks to health.

4. Controlled Consumption Quantity

Mulberry leaf tea should be consumed in moderation. Excessive intake may lead to adverse effects on the body. Long-term, high-volume consumption may cause side effects such as inhibition of digestive enzymes or irritation of the gastrointestinal tract.

5. Avoid Drinking on an Empty Stomach

Drinking mulberry leaf tea on an empty stomach allows the tea to directly affect the kidney meridian, which may be detrimental to kidney health. Therefore, it is advisable to avoid consuming mulberry leaf tea before meals to protect overall health.

If choosing to drink mulberry leaf tea, individuals should consume it in appropriate amounts according to their personal health condition to achieve optimal benefits.
