- Anti-inflammatory: Traditionally used to reduce swelling and ease joint pain.
- Antiseptic: Extracts have been used for wound healing.
- Antimicrobial: Research indicates antibacterial properties.
Comparison of Nutrients: Fresh vs. Dried Tamarind Leaves
Processing can affect the nutritional content of the leaves. This table, based on various studies, shows how dehydration can alter nutrient concentration.
| Nutrient | Fresh Leaves (per 100g) | Dried Powder (per 100g) | Notes |
|---|---|---|---|
| Protein | ~6g | ~4.08g | Protein levels decrease after dehydration. |
| Carbohydrates | ~18g | ~86.26g | Dehydration significantly increases the carbohydrate concentration relative to weight. |
| Vitamin C | ~50mg | ~2.40mg | Vitamin C is sensitive to heat and oxygen, leading to a substantial reduction during drying. |
| Calcium | ~101mg | ~96.4mg | Mineral content is relatively stable, with slight reductions potentially due to processing. |
| Iron | ~0.18mg | ~0.18mg | Mineral content is relatively stable, with minimal changes during processing. |
| Beta-Carotene | ~168.8μg | ~166.8μg | Similar to Vitamin C, beta-carotene can be affected by processing, though levels can remain substantial. |
Considerations and Safety
Tamarind leaves are generally safe, but consuming them in excess may cause discomfort due to high fiber content. Those with legume allergies should be cautious. Consult a healthcare provider before using them medicinally, especially regarding potential drug interactions. Research has highlighted the antioxidant and hepatoprotective properties of tamarind leaf extracts.
