You might walk past a white mulberry tree without paying much attention—but this modest-looking plant has been valued for thousands of years in traditional medicine systems. Today, modern scientific research is beginning to validate what ancient cultures long believed: white mulberry may help support healthy blood sugar levels, cardiovascular function, inflammation control, and antioxidant protection.

Below is a clear, science-informed overview of what white mulberry offers, what current research actually supports, and how it has traditionally been used.

A Plant With Deep Historical Roots

White mulberry (Morus alba) has a rich and fascinating history. It was introduced to the United States during colonial times as part of an ambitious effort to establish a domestic silk industry, since silkworms rely almost entirely on its leaves for nourishment. Although the silk trade never became economically successful, the tree adapted extremely well to its new environment and now grows widely across North America, Europe, and Asia.

In addition to its role in silk production, white mulberry wood has long been valued for its strength and durability. Historically, it has been used to make furniture, agricultural tools, boats, and even sports equipment.

In recent years, scientific focus has shifted from the wood to the leaves and berries, which contain a diverse range of bioactive compounds associated with multiple health-supporting effects.

Key Health Benefits of White Mulberry

1. Supports Healthy Blood Sugar Levels

White mulberry is best known for its ability to help regulate blood sugar.

Its leaves contain 1-deoxynojirimycin (DNJ), a naturally occurring compound that slows the digestion of carbohydrates. By inhibiting enzymes responsible for breaking down starches into glucose, DNJ delays sugar absorption in the intestines and helps reduce sharp post-meal blood sugar spikes.

Because of this unique mechanism, white mulberry has been widely studied for its potential role in supporting people with prediabetes, insulin resistance, and type 2 diabetes. Several studies suggest it may improve insulin sensitivity and help stabilize glucose levels when used alongside a healthy diet.

2. Supports Heart and Circulatory Health

White mulberry contains antioxidants and plant-based compounds that may help:

• Lower LDL (“bad”) cholesterol

• Improve blood vessel elasticity

• Support healthy blood pressure levels

Together, these effects may reduce strain on the cardiovascular system and contribute to long-term heart health when combined with regular physical activity and balanced nutrition.

3. Antioxidant Activity and Cancer-Related Research

White mulberries naturally contain resveratrol, a well-known antioxidant also found in grapes and red wine.

Laboratory and early-stage research suggests resveratrol may:

• Protect cells from oxidative damage

• Reduce inflammation

• Interfere with abnormal cell growth pathways

While these findings are promising, human clinical studies remain limited. White mulberry should not be viewed as a cancer treatment but rather as a supportive dietary source of protective antioxidants that may help reduce cellular stress.

4. Immune Support and Anti-Inflammatory Effects

Thanks to its vitamin C content and high levels of polyphenols and flavonoids, white mulberry may help:

• Strengthen immune defenses

• Reduce chronic low-grade inflammation

• Protect cells from oxidative stress associated with aging

These properties make white mulberry attractive for general wellness, seasonal immune support, and long-term vitality.

5. Traditional Support for Respiratory and Joint Comfort

In traditional herbal systems—especially in Chinese medicine—white mulberry leaf tea has been used to:

• Ease coughs and sore throats

• Support lung function

• Help reduce mild fever

• Relieve muscle stiffness and joint discomfort

Although these uses are largely based on traditional practice rather than large-scale clinical trials, they remain popular in modern herbal medicine.

6. Digestive Health Support

White mulberry provides dietary fiber and pectin, which may:

• Promote regular bowel movements

• Support healthy gut bacteria

• Aid nutrient absorption

Organic acids in the fruit may also stimulate digestive enzymes and improve gastrointestinal comfort, making white mulberry beneficial for overall digestive balance.

7. Skin, Hair, and Scalp Wellness

In traditional Chinese medicine, white mulberry has been associated with:

• Supporting hair strength and scalp health

• Reducing dizziness and ringing in the ears

• Helping maintain youthful-looking skin

Its antioxidant compounds may help limit oxidative damage that contributes to premature skin aging and loss of skin elasticity.

Nutritional Highlights

White mulberry leaves and berries contain:

• Vitamin C – immune support and tissue repair

• B vitamins – energy metabolism and nervous system health

• Fiber and pectin – digestive function

• Polyphenols and flavonoids – antioxidant protection

• Resveratrol – cellular and cardiovascular support

• Carotene and organic acids – metabolism and skin health

What Research Suggests

• Multiple studies support white mulberry’s ability to reduce fasting blood sugar and improve insulin sensitivity

• Research confirms the presence of resveratrol and links it to antioxidant and cardiovascular benefits

• Cholesterol-lowering and anti-inflammatory effects have also been observed

Overall, the strongest scientific evidence supports its role in metabolic and blood sugar health, while other potential benefits continue to be explored through ongoing research.

Safety Considerations

White mulberry is generally considered safe when consumed in moderate amounts. However:

• People taking diabetes medications should consult a healthcare professional, as blood sugar may drop too low

• Pregnant or breastfeeding individuals should avoid high-dose supplements due to limited safety data

• Teas and food forms are typically gentler than concentrated extracts

How to Use White Mulberry

• Tea: Brew dried leaves for a mild, earthy herbal drink

• Capsules or extracts: For standardized intake (follow product instructions)

• Fresh or dried berries: Eat as a snack or add to yogurt, oatmeal, smoothies, or salads

Final Thoughts

Often overlooked, white mulberry is a remarkably versatile plant with deep historical roots and growing scientific support. From blood sugar balance to antioxidant protection and immune wellness, it offers meaningful benefits when used thoughtfully and consistently.

While it is not a cure-all, incorporating white mulberry into a balanced lifestyle may provide a simple, natural way to support long-term health and overall well-being.
