You’ve probably walked past it a hundred times — its broad leaves rustling in the breeze, its fruit staining sidewalks with purple splashes each summer.
It’s the white mulberry tree (Morus alba ), a common sight in backyards, parks, and city streets across the U.S. and beyond.
But what most people see as just another shade tree, traditional healers and modern researchers see as a powerhouse of natural medicine .
Recent studies reveal that white mulberry — from its leaves, fruit, and bark — may help:
✅ Lower blood sugar in diabetics
✅ Reduce high blood pressure
✅ Support heart health
✅ Fight tumor growth and cancer cells
✅ Boost immune function and liver health
And the best part? This medicinal marvel is likely growing just blocks from your home.
Let’s dive into the science-backed health benefits of white mulberry — and why this overlooked plant deserves a spot in your wellness routine.
What Is White Mulberry?
The white mulberry (native to China but now widespread in North America) has been used for thousands of years in traditional Chinese medicine .
While its leaves were originally cultivated to feed silkworms , healers soon discovered their therapeutic potential .
Today, modern science confirms what ancient practitioners knew: white mulberry is loaded with bioactive compounds like:
1-Deoxynojirimycin (DNJ) – A powerful compound that slows sugar absorption
Resveratrol – The same antioxidant found in red wine
Flavonoids and polyphenols – Potent anti-inflammatory and antioxidant agents
These compounds are found in the leaves, fruit, and root bark , making nearly every part of the tree useful.
7 Science-Backed Health Benefits of White Mulberry
1. Helps Control Blood Sugar & Manage Diabetes
One of the most studied benefits of white mulberry is its anti-diabetic effect .
The compound DNJ blocks an enzyme in the gut (alpha-glucosidase ) that breaks down carbohydrates — slowing sugar absorption and preventing blood sugar spikes .
✅ A 2020 study in Phytomedicine found that mulberry leaf extract significantly reduced fasting blood glucose in type 2 diabetics.
✅ Another study showed it improved insulin sensitivity and HbA1c levels.
💡 Many people take mulberry leaf tea or supplements as a natural support for blood sugar balance.
2. May Help Prevent or Slow Tumor Growth
Emerging research suggests white mulberry has anti-cancer properties .
Studies show that mulberry extracts :
Inhibit the growth of breast, liver, and colon cancer cells in lab studies
Trigger apoptosis (programmed cell death) in tumor cells
Reduce inflammation and oxidative stress , which contribute to cancer development
While more human trials are needed, the results are promising — especially for preventive nutrition .
3. Lowers High Blood Pressure & Supports Heart Health
White mulberry helps relax blood vessels and improve circulation thanks to its antioxidant and anti-inflammatory effects .
It may:
Reduce LDL (bad) cholesterol
Increase HDL (good) cholesterol
Lower triglycerides
Improve endothelial function (blood vessel health)
This makes it a natural ally for cardiovascular wellness — especially when combined with a healthy diet and lifestyle.
4. Rich in Antioxidants That Fight Aging
The fruit and leaves are packed with antioxidants that neutralize free radicals — molecules that damage cells and accelerate aging.
Regular consumption may:
Protect brain health
Support liver function
Slow skin aging
Reduce chronic inflammation
🍇 Mulberry fruit has more antioxidants than blueberries by weight!
5. Supports Weight Management
Because it slows carbohydrate digestion, white mulberry may help:
Reduce cravings
Prevent fat storage
Support healthy metabolism
It’s often included in natural weight-loss supplements for this reason.
6. Boosts Immune Function
Polysaccharides in mulberry leaves have been shown to stimulate immune cells , helping the body fight off infections more effectively.
7. Improves Liver Health
Animal studies suggest mulberry extract can protect the liver from fatty buildup and toxin damage — making it a potential aid for fatty liver disease .
