1. Mango Leaves

Mango leaves, especially young ones, contain tannins and anthocyanins that may improve insulin function. Research suggests they can help reduce post-meal spikes in blood sugar.

• Or dry the leaves, grind into powder, and stir one teaspoon into warm water.

2. Guava Leaves

Guava leaves are rich in antioxidants and may reduce sugar absorption in the intestines. Studies show guava leaf tea can lower post-meal glucose and improve cholesterol.

How to use:

• Wash and boil a handful of guava leaves for 10 minutes.
• Strain and drink once or twice daily.

3. Insulin Plant Leaves (Costus igneus)

Known as the “insulin plant,” this leaf is widely used in Asia to support healthy blood sugar. Research indicates it may enhance insulin sensitivity and glucose uptake.

How to use:

• Chew one fresh, clean leaf daily.
• Or dry the leaves, crush into powder, and brew as tea.

4. Neem Leaves

Neem, or Indian lilac, has antibacterial and anti-inflammatory properties. It may also support glucose metabolism and lower blood sugar levels.

How to use:

• Crush a few fresh neem leaves and consume with water.
• Or drink neem tea made from dried leaves.

5. Mulberry Leaves

Mulberry leaves help slow carbohydrate absorption, preventing blood sugar spikes after meals. They also contain antioxidants that protect against diabetes-related complications.
