HORMONE BALANCE

White Mulberry Leaf

Morus alba

also known as mulberry leaf

Moderate (blood sugar)

Leaves from the same tree whose fruit feeds silkworms, used in traditional Chinese medicine for over a thousand years. Modern research focuses on a specific compound in the leaf that blocks the digestion of carbohydrates — making white mulberry leaf one of the better-studied herbs for blood sugar after meals.

Reduces the blood sugar spike after carbohydrate-rich meals
Contains a compound (1-deoxynojirimycin, DNJ) that blocks the same enzyme targeted by acarbose, a prescription diabetes medication
May modestly lower fasting blood sugar with consistent use
May modestly lower cholesterol
Most effective when taken just before meals containing starch or sugar
Long traditional Chinese medicine use as a 'cooling' herb for diabetes-related thirst and sugar imbalance

Use caution with diabetes medication — additive blood sugar lowering

Can cause mild digestive upset, gas, or diarrhea — especially when first starting

Stop two weeks before surgery

Skip during pregnancy and nursing — limited safety data

Best paired with diet and lifestyle changes for blood sugar management — works as part of a bigger picture
