Health Benefits & Sources
Why You Need It
- Respiratory Support: Loquat leaf is famous for its ability to calm coughs and loosen phlegm. It acts as a natural expectorant, making breathing easier during cold season.
- Antioxidant Powerhouse: The fruit is rich in phenolic compounds and vitamin C, which help neutralize harmful free radicals and reduce oxidative stress in the body.
- Blood Sugar Balance: Early research suggests that loquat leaves may help improve insulin sensitivity, supporting healthy glucose metabolism.
- Anti-inflammatory: Compounds like ursolic acid found in Loquat help reduce inflammation, which is key for joint health and overall longevity.
Deep Dive
The magic of Loquat lies in its unique blend of bioactive compounds. The fruit provides a potent dose of Vitamin A (great for vision and skin) and dietary fiber (excellent for digestion). However, the leaves contain a special compound called Ursolic Acid and Amygdalin (also known as Vitamin B17). While Amygdalin is controversial (see safety section), when used correctly in traditional medicine, it is believed to support cellular health. The leaves are often brewed into a tea to suppress dry coughs and soothe the throat lining, acting as a demulcent.
Natural Food Sources
The best way to consume Loquat is by eating the fresh fruit. The leaves are generally used in teas or extracts rather than eaten raw.
| Food Source | Amount (Per 100g) | % Daily Value (Approx) |
|---|---|---|
| Loquat Fruit (Raw) | 1 Serving | 40% |
| Vitamin C | 15mg | ~17% |
| Vitamin A | 760 IU | ~15% |
| Fiber | 1.7g | ~7% |
Supplementation
While eating the fruit is delicious, the potent respiratory benefits are usually derived from Loquat Leaf Extract. This is available in capsules, powders, or liquid tinctures.
- Usage: It is typically taken to suppress coughs or support immune response during illness.
- Dosage: Follow the manufacturer's instructions on the specific supplement. There is no standard RDA for loquat leaf extract, but extracts are usually standardized for triterpenes.
Note: Always prioritize the fruit for daily nutrition; use supplements for targeted support.

Safety & Side Effects
Safety First:
- The Fruit: Is generally recognized as safe for most people. However, the seeds (pits) inside the fruit contain amygdalin, a compound that releases cyanide when digested. Do not chew or swallow the seeds.
- The Leaves: Loquat leaf preparations should be avoided by pregnant or breastfeeding women due to a lack of safety data.
- Amygdalin (Vitamin B17): While some alternative therapies use it, high doses can be toxic. Stick to standard supplement dosages.
- Interactions: If you are on medication for diabetes (as Loquat may lower blood sugar further) or diuretics, consult your doctor.
