White mulberry, Morus alba, has long nourished silkworms and featured in Thai traditional medicine. In Thai Isan and broader East Asia, leaves are boiled for fevers, added to tonics for recovery, and eaten as a green with nutritional value. Thai practitioners view these leaves as supporting liver health, acting as mild diuretics, and easing “wind” symptoms, a concept rooted in humoral health. This cultural reverence is echoed in Thai pharmacopoeia and herbal clinics, highlighting the leaf’s enduring relevance and its connection to East Asian botanical heritage.
Modern science is increasingly validating these traditional uses. The leaves contain bioactive compounds such as alkaloids, flavonoids (including rutin and quercetin), and the compound 1-deoxynojirimycin (DNJ). These substances influence blood sugar regulation, lipid metabolism, and inflammation, with antioxidant effects noted in multiple studies. Research by reputable journals and health outlets suggests these phytochemicals may contribute to metabolic health and cardiovascular markers when used as part of a broader lifestyle approach.
The most widely publicized finding is the leaf’s role in diminishing post-meal glucose spikes. DNJ acts as a natural alpha-glucosidase inhibitor, slowing carbohydrate digestion and reducing quick sugar surges after meals. Randomized trials indicate that regular Morus alba leaf extract can improve glycemic control in type 2 diabetes and may modestly support lipid balance and weight management. A 12-week study in adults with diabetes demonstrated improvements in glucose profiles and cardiovascular markers, aligning with traditional uses for managing “sweet urine” conditions.
Beyond glucose control, Morus alba leaves and berries show a broad spectrum of bioactivities. Reviews of animal and cellular studies point to anti-atherosclerotic, liver-protective, antimicrobial, and neuroprotective effects. The diverse antioxidant content helps combat oxidative stress and promote healthy inflammation. Some human trials also suggest weight management benefits through appetite regulation and enhanced energy metabolism.
As with any health trend, expectations should be measured. While several small human studies report positive metabolic effects, larger, high-quality trials are needed to determine optimal dosages, long-term safety, and the full range of benefits and risks. Thai and international experts emphasize cautious use, especially for individuals on blood sugar-lowering medications, and recommend consulting healthcare professionals before starting concentrated extracts or supplements.
Traditional Thai preparation typically involves drying and brewing leaves into teas, hot or cold. Mulberry leaf blends with local botanicals—lemongrass, jasmine, and pandanus—produce fragrant infusions prized for taste and wellness. In Isan cooking, young leaves may appear in soups or omelets, adding earthiness and micronutrients such as iron, calcium, and vitamin C. The plant thus remains a staple in both daily life and cultural rituals, supporting health, local economies, and agrotourism through mulberry-based teas and products.
Safety considerations remain important. Overall, Morus alba is considered safe when consumed in typical dietary amounts. Some people may experience digestive upset, bloating, or dizziness with higher-dose products. Individuals with chronic gastrointestinal conditions or those on hypoglycemic medications should seek medical advice before using concentrated extracts or supplements. Pregnant or breastfeeding individuals are advised to avoid herbal supplements due to limited safety data. The growing popularity of mulberry-based weight management products calls for careful brand selection and quality assurance.
Historically, Morus alba is linked to the spread of sericulture in Thailand, with mulberry groves shaping both silk production and rural livelihoods. Today, agro-tourism and One Tambon One Product (OTOP) initiatives showcase mulberry-based teas and foods as cultural assets and economic drivers. Thai communities continue to celebrate mulberry through festivals and local products, underscoring a living link between tradition and modern enterprise.
As the plant attracts patent scrutiny and wellness marketing globally, Thai herbalists and policymakers advocate for fair recognition of local knowledge. The World Health Organization and Thailand’s Department of Thai Traditional and Alternative Medicine encourage responsible research and culturally sensitive promotion of herbal medicines, integrating scientific rigor with traditional wisdom.
Looking ahead, Morus alba could play a larger role in biotechnology, nutraceuticals, and functional foods. Sustainable farming and community-led innovation can keep the tree rooted in both heritage and modern health landscapes. Thailand has an opportunity to model how scientific inquiry and cultural pride can advance together.
Practical guidance for Thai readers considering Morus alba: start with traditional preparations, such as leaf tea and incorporating young leaves into recipes, to experience gentle benefits. If considering extracts or supplements, choose products with clear labeling and independent quality testing. Remember that Morus alba should complement a balanced diet and healthy lifestyle, not replace medical care. Consult a qualified healthcare provider if you have chronic conditions or take prescription medications before adding herbal remedies.
The story of Morus alba—woven through silk, tradition, and science—illustrates how ancient knowledge can inform contemporary health. By honoring both heritage and evidence, Thailand can lead in safe, culturally attuned wellness innovation.
