Dried Longan

Dried longan contains gallic acid and vitamin C that support immune function and provide antioxidant protection. The fruit's natural compounds promote sleep quality by modulating neurotransmitter activity in the central nervous system.

Origin & History

Longan is native to Southern Asia, particularly in regions like India and Sri Lanka. The drying process enhances its sweetness and preserves its nutrients.

Historical & Cultural Context

Longan has been used in traditional Chinese medicine for its calming effects and health benefits.

Health Benefits

- Supports immune health with vitamin C, crucial for fighting infections. This enhances the body's natural defenses. - Rich in antioxidants like gallic acid, reducing oxidative stress and inflammation. This protects against chronic illnesses. - Promotes restful sleep with natural compounds that calm the nervous system. This improves sleep quality and duration. - Aids in digestion with dietary fiber, supporting regular bowel movements. Fiber also nourishes beneficial gut bacteria. - Enhances cognitive function with iron, which improves oxygen transport to the brain. This boosts mental clarity and focus. - Supports heart health by reducing cholesterol levels with polyphenols. This decreases the risk of cardiovascular disease. - Boosts energy levels with natural sugars, providing a quick energy source. This is ideal for combating fatigue.

How It Works

Gallic acid in dried longan inhibits pro-inflammatory enzymes like cyclooxygenase and lipoxygenase while scavenging reactive oxygen species. Vitamin C enhances neutrophil function and supports collagen synthesis for immune barrier integrity. Natural adenosine-like compounds may interact with GABA receptors to promote sedative effects.

Scientific Research

Emerging research suggests that longan may improve sleep quality and support immune health due to its nutrient content.

Clinical Summary

Limited human studies exist on dried longan specifically. In vitro studies demonstrate antioxidant activity with IC50 values around 15-25 μg/mL for gallic acid extracts. Small observational studies (n=30-50) suggest improved sleep quality scores after 2-3 weeks of consumption. Most evidence comes from traditional use patterns rather than controlled clinical trials.

Nutritional Profile

- High in vitamin C and B vitamins. - Contains antioxidants like polyphenols. - Low in calories and fat. - Provides dietary fiber and potassium.

Preparation & Dosage

Consume 20-30 grams daily as a snack or in recipes. Consult a healthcare provider before use.

Synergy & Pairings

Ginger, Chamomile, Almond, Goji Berry

Safety & Interactions

Dried longan is generally safe for most adults when consumed in food amounts. High doses may cause digestive upset or diarrhea due to natural sugars and fiber content. No significant drug interactions reported, but blood sugar monitoring recommended for diabetics due to natural fructose content. Safety during pregnancy and breastfeeding lacks sufficient data.
