White Mulberry: A Comprehensive Guide to its Uses, Side Effects, Precautions, and Dosing


White mulberry (Morus alba), a deciduous tree native to China, has been employed for centuries in traditional medicine. Its leaves and fruit are particularly renowned for their therapeutic properties, owing to their rich content of bioactive compounds, including flavonoids, alkaloids, and vitamins. This article delves into the versatile uses, potential side effects, and essential precautions associated with white mulberry supplementation.

Uses of White Mulberry

  • Blood Sugar Regulation: White mulberry leaves contain compounds known as 1-deoxynojirimycin (DNJ) and flavonoids, which have been shown to inhibit the enzymes involved in carbohydrate digestion, resulting in slower absorption of sugar into the bloodstream. This property makes white mulberry a potential adjunct therapy for managing type 2 diabetes.
  • Weight Management: By delaying carbohydrate absorption, white mulberry may also promote satiety and reduce overall calorie intake, potentially aiding in weight loss efforts.
  • Cardiovascular Health: The flavonoids and antioxidants present in white mulberry leaves possess anti-inflammatory and antioxidant properties, which may help protect against oxidative stress and inflammation associated with cardiovascular diseases. Some studies suggest that white mulberry supplementation may reduce cholesterol levels and improve blood pressure.
  • Antioxidant Activity: White mulberry is a potent source of antioxidants, including resveratrol and flavonoids, which combat free radicals and protect cells from damage. This antioxidant activity may contribute to the tree’s potential role in preventing age-related diseases and certain types of cancer.
  • Immune System Support: Some research indicates that white mulberry leaves may possess immune-modulating properties, potentially enhancing the body’s response to pathogens.
  • Anti-Inflammatory: The anti-inflammatory compounds in white mulberry may be beneficial in reducing inflammation associated with conditions such as arthritis, asthma, and inflammatory bowel disease.

Side Effects of White Mulberry

While generally well-tolerated, white mulberry supplementation can cause some adverse effects, especially at high doses:

  • Gastrointestinal Problems: Consumption of large amounts of white mulberry leaves or fruit may cause mild gastrointestinal distress, such as nausea, vomiting, or diarrhea.
  • Allergic Reactions: Individuals allergic to mulberry or related plants may experience allergic reactions, such as skin rashes, hives, or difficulty breathing.
  • Drug Interactions: White mulberry may interact with certain medications, including blood thinners and antidiabetic drugs. It is essential to consult a healthcare provider before using white mulberry supplements if you are taking any medications.
  • Hypoglycemia: White mulberry can lower blood sugar levels, which may lead to hypoglycemia (low blood sugar) in individuals with diabetes or those taking blood sugar-lowering medications. It is crucial to monitor blood sugar levels closely while using white mulberry.
  • Kidney Problems: Excessive consumption of white mulberry may put stress on the kidneys, potentially leading to kidney stones or other kidney issues.

Precautions and Warnings

  • Pregnancy and Breastfeeding: Safety during pregnancy and breastfeeding has not been established for white mulberry supplementation. Therefore, it is best to avoid its use during these periods.
  • Children: The appropriate dosage and safety of white mulberry supplements for children have not been determined. Parents should consult a healthcare provider before giving white mulberry to their children.
  • Liver Disease: Liver disease may impair the metabolism of white mulberry compounds, potentially increasing the risk of side effects. Consult a healthcare provider before using white mulberry if you have liver disease.
  • Allergic Reactions: As mentioned earlier, individuals with allergies to mulberry or related plants should avoid white mulberry supplements.

Dosing Recommendations

The appropriate dosage of white mulberry supplements varies depending on the form (e.g., leaves, extract) and intended use. It is essential to follow the manufacturer’s instructions and consult a healthcare provider for personalized guidance.

  • Leaf Powder: 5-10 grams of dried white mulberry leaves per day
  • Extract: 100-200 mg of white mulberry extract standardized for DNJ content per day
  • Tea: 1-2 cups of white mulberry leaf tea per day


White mulberry is a versatile natural supplement with various potential health benefits, including blood sugar regulation, weight management, and antioxidant activity. However, it is essential to exercise caution when using white mulberry, as excessive intake or use with certain conditions or medications may cause side effects. By following appropriate dosing guidelines, paying attention to precautions, and consulting a healthcare provider, individuals can safely benefit from this natural remedy’s therapeutic properties.
