Researchers in the United Arab Emirates studied two types of mulberry plants to see what healthy nutrients and germ-fighting powers they have. They tested leaves, branches, and roots from both native black mulberry and white mulberry plants. The black mulberry was packed with calcium and other minerals, while the white mulberry had more protein and fiber. Both plants showed impressive ability to kill harmful bacteria and fungi, especially the white mulberry. These findings suggest mulberry plants could be valuable for natural medicine and food supplements, supporting their traditional use in Middle Eastern folk medicine.

The Quick Take

  • What they studied: Whether two different mulberry plants grown in the UAE have different amounts of healthy minerals and whether they can kill harmful bacteria and fungi
  • Who participated: The study examined plant samples (leaves, branches, and roots) from black mulberry and white mulberry plants found in Fujairah, UAE. No human participants were involved.
  • Key finding: Both mulberry types showed strong germ-fighting abilities, with white mulberry being particularly effective. Black mulberry leaves contained extremely high calcium (1,514 mg per 100g), while white mulberry had more protein and fiber. Neither plant contained dangerous heavy metals.
  • What it means for you: Mulberry plants appear to be safe and nutritious foods that may help fight infections naturally. However, more research in humans is needed before using them as medicine replacements. They could be a healthy addition to your diet.

The Research Details

Scientists collected samples from two mulberry species growing wild in the UAE and analyzed them in a laboratory. They tested different parts of each plant (leaves, branches, and roots) separately to see what minerals and nutrients each contained. They used specialized equipment to measure calcium, potassium, magnesium, and other important minerals. They also tested whether the plants could stop the growth of common bacteria and fungi that cause infections in humans.

The researchers used standard scientific methods to measure nutrients like protein, fiber, and special plant compounds called flavonoids and tannins. They tested the plants against six different types of harmful germs: four bacteria species and two fungal species. They measured how well each plant part stopped the germs from growing by looking at clear zones around the plant material.

This research is important because it’s the first study to scientifically test mulberry plants from the UAE, even though people there have used them in traditional medicine for centuries. By measuring exactly what’s in these plants and testing their germ-fighting abilities, scientists can understand why traditional medicine works and whether these plants are safe and effective. This helps bridge the gap between folk medicine and modern science.

The study used established scientific methods recognized by official analytical chemistry organizations. The researchers tested multiple plant parts and multiple types of germs, which makes the findings more reliable. They used statistical analysis to ensure their results weren’t due to chance. However, the study only tested plants in a laboratory, not in living organisms, so real-world effectiveness may differ. The sample size of plant material tested wasn’t specified, which is a limitation.

What the Results Show

Black mulberry (Morus nigra) leaves contained exceptionally high calcium at 1,514 mg per 100g—enough to meet an entire day’s calcium needs in just that amount. The roots of black mulberry were rich in magnesium, phosphorus, and other minerals. White mulberry (Morus alba) showed different strengths, with higher protein content (8.14g per 100g in leaves) and more fiber (25.97% in leaves). White mulberry also contained more flavonoids, which are plant compounds known for fighting germs.

Both plants successfully stopped the growth of harmful bacteria and fungi. White mulberry was more effective overall, with the strongest effect against Staphylococcus aureus bacteria (a common cause of skin infections), creating a clear zone of 32.66 millimeters where germs couldn’t grow. The plants were better at fighting bacteria than fungi. Importantly, neither plant contained dangerous heavy metals like lead or cadmium, making them safe to eat.

Black mulberry leaves had high ash content (8.77%) and tannins (4.16%), which are compounds that may have additional health benefits. White mulberry branches had the highest dry matter content (74.45%), suggesting they’re more concentrated in nutrients. The roots of white mulberry showed the strongest antimicrobial activity overall. Interestingly, white mulberry showed no detectable phenolic content, which differs from some other plant studies. Both plants had very low fat content, making them potentially good for people watching their fat intake.

Previous studies have shown mulberry plants have health benefits, but this is the first detailed analysis of UAE-grown varieties. The calcium levels found in black mulberry leaves are notably higher than previously reported in other mulberry studies, suggesting that growing conditions in the UAE may produce particularly nutrient-rich plants. The antimicrobial findings align with traditional uses of mulberry in Middle Eastern folk medicine, providing scientific support for practices that have been used for generations.

This study only tested plants in laboratory conditions, not in actual human bodies or real infections, so the effectiveness in real life may be different. The exact amount of plant material tested wasn’t clearly specified. The study didn’t test how the plants would work when cooked or processed, which is how people typically consume them. Only six types of germs were tested, so effectiveness against other harmful microorganisms is unknown. The study doesn’t explain why one species is better than another, just that they are different.

The Bottom Line

Based on this research, mulberry plants appear to be nutritious foods that are safe to eat (no dangerous heavy metals detected). Black mulberry may be especially good for calcium intake, while white mulberry offers more protein and fiber. However, these findings suggest potential, not proven medical treatments. Do not use mulberry plants to replace antibiotics or antifungal medications prescribed by doctors. More research in humans is needed before making health claims. Confidence level: Moderate for nutritional content, Low for medical applications.

People interested in traditional medicine, those looking for natural nutrient sources, and researchers studying plant-based remedies should find this valuable. Anyone with calcium or protein deficiencies might benefit from including mulberry in their diet. However, people taking medications that interact with plant compounds should consult their doctor first. This research is not a substitute for medical treatment of infections.

If using mulberry as a food source, nutritional benefits would be immediate with regular consumption. If hoping for antimicrobial effects, there’s no established timeline since human studies haven’t been done. Any health improvements would likely take weeks to months of consistent use, similar to other dietary changes.

Want to Apply This Research?

  • Track daily mulberry consumption (in grams or servings) and note any changes in energy levels, digestion, or general wellness over 4-8 weeks. Record which plant part you consumed (leaves, branches, or roots) and preparation method.
  • Add mulberry leaves or dried mulberry to your daily diet through smoothies, teas, or as a snack. Start with small amounts (1-2 tablespoons) to see how your body responds. Keep a food diary noting when you consume mulberry and any effects you notice.
  • Use the app to log mulberry intake weekly and track general health markers like energy, digestion, and any infections or illness. Set reminders for consistent consumption. Compare monthly wellness scores to establish patterns. Share data with your healthcare provider if using mulberry alongside medical treatment.

This research describes laboratory findings about mulberry plant composition and germ-fighting properties. These results do not prove that mulberry plants can treat or cure infections in humans. Do not use mulberry plants as a replacement for prescribed antibiotics, antifungal medications, or other medical treatments. Always consult with a healthcare provider before using plant-based remedies, especially if you take medications or have existing health conditions. While the study found no heavy metals in these plants, individual plants may vary. Pregnant women and nursing mothers should consult their doctor before consuming mulberry supplements.
