4 Side Effects Of Mulberry You Should Know
1. May Lead To Hypoglycemia
Mulberries are known to lower blood sugar with increased insulin hormone levels. In studies, mulberry extracts could lower blood sugar levels in normal and diabetic mice (1), (2), (3). Mulberry is rich in flavonoids and polyphenols that combat oxidative stress (4). In humans, mulberry tea suppresses the postprandial rise of blood glucose levels after 90 minutes since its consumption (5). Mulberry leaf extracts, like α-glucosidase, may help delay carbohydrate digestion (5), (6). This can lead to a sudden drop in blood glucose levels, especially in those already on diabetic medication, which may eventually lead to liver damage. As per anecdotal evidence, the symptoms may include hunger, headache, blurred vision, excessive sweating, dizziness, confusion, and tremors. Mulberries, hence, must be eaten with caution. It is important to consult a licensed medical professional if you are planning on taking mulberry extract herbal supplements to treat diabetes or obesity.

Moreover, the latex (milky white sap) from mulberries is toxic, especially to insects and caterpillars (8). This latex can cause mild skin irritation in humans. It is not advisable to ingest it as it may cause stomach cramps, bloating, and diarrhea.
3. May Hinder Carbohydrate Absorption
Mulberries are known to hinder carbohydrate absorption (8). Research shows that inhibition of carbohydrate absorption may help in weight control and diabetes treatment. A study published in The American Journal of Clinical Nutrition reports that tea extracts (including mulberry) resulted in carbohydrate malabsorption (8). This property of mulberry can interfere with the optimal absorption of nutrients and lead to detrimental effects in the body.
4. May Have A Detrimental Effect On Kidneys
Mulberry leaves may help relieve the symptoms of gout by lowering uric acid levels (9). Hence, avoid taking mulberry leaves if you are already on medication to lower uric acid levels. Mulberries are also high in potassium, which is integral for the proper functioning of the body (10). Anecdotal evidence suggests that high levels of potassium may result in dehydration and internal bleeding. High potassium levels may also cause fatigue, numbness, nausea, irritability, chest pain, irregular heartbeats, and palpitations. Hence, people with chronic kidney disease must limit or even avoid mulberry intake to prevent possible kidney damage.
