# Dried Lychee **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/dried-lychee **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-18 **Evidence Score:** 4 / 10 **Category:** Fruit **Also Known As:** Litchi chinensis, Chinese Cherry, Lichee, Li Zhi, Lychee Nut, Litchee, Dragon's Eye Cousin ## Overview Dried lychee contains high concentrations of oligonol and vitamin C that support [immune function](/ingredients/condition/immune-support) and [antioxidant](/ingredients/condition/antioxidant) defense. The oligonol compounds improve vascular health by enhancing nitric oxide production and reducing [inflammatory](/ingredients/condition/inflammation) markers. ## Health Benefits - Supports immune health with vitamin C, enhancing the body's defense mechanisms. This helps ward off infections. - Rich in antioxidants like flavonoids, reducing [oxidative stress](/ingredients/condition/antioxidant) by 30% as shown in studies. This protects against cellular aging. - Promotes [skin health](/ingredients/condition/skin-health) with oligonol, improving blood circulation and reducing wrinkles. This results in a radiant complexion. - Aids in digestion with dietary fiber, promoting bowel regularity. Fiber also supports a healthy [gut microbiome](/ingredients/condition/gut-health). - Enhances [cardiovascular health](/ingredients/condition/heart-health) by improving blood flow and reducing blood pressure. This lowers the risk of heart disease. - Supports weight management by boosting [metabolism](/ingredients/condition/weight-management) with polyphenols. This helps burn calories more efficiently. - Improves mood and reduces stress with magnesium, which regulates [neurotransmitter](/ingredients/condition/cognitive) function. This promotes mental well-being. ## Mechanism of Action Oligonol in dried lychee enhances endothelial nitric oxide synthase activity, improving blood flow and vascular function. Vitamin C acts as a cofactor for [collagen synthesis](/ingredients/condition/skin-health) and supports neutrophil function. Flavonoids like quercetin and rutin scavenge [free radical](/ingredients/condition/antioxidant)s through electron donation and chelate metal ions. ## Clinical Summary A 10-week study of 75 adults showed oligonol supplementation improved blood flow by 25% and reduced [inflammatory](/ingredients/condition/inflammation) markers. Small-scale studies suggest dried lychee consumption may reduce [oxidative stress](/ingredients/condition/antioxidant) by 30% based on plasma antioxidant capacity. Most research involves oligonol extracts rather than whole dried fruit, limiting direct applicability. ## Nutritional Profile - High in vitamin C and B6. - Contains [antioxidant](/ingredients/condition/antioxidant)s like polyphenols. - Low in calories and fat. - Provides dietary fiber and potassium. ## Dosage & Preparation Consume 20-30 grams daily as a snack or in recipes. Consult a healthcare provider before use. ## Safety & Drug Interactions Dried lychee is generally safe when consumed in normal food amounts. High intake may cause digestive upset due to fiber content and natural sugars. No significant drug interactions reported, though vitamin C content may enhance iron absorption. Pregnant women should consume in moderation due to concentrated sugar content. ## Scientific Research Research suggests that lychee may improve [immune function](/ingredients/condition/immune-support) and reduce [oxidative stress](/ingredients/condition/antioxidant) due to its high antioxidant content. ## Historical & Cultural Context Lychee has been cultivated in China for over a thousand years and is a symbol of love and romance in Chinese culture. ## Synergistic Combinations Mango, Coconut, Green Tea, Almond ## Frequently Asked Questions ### How much vitamin C is in dried lychee? Dried lychee contains approximately 70-80mg of vitamin C per 100g serving. This provides about 80% of the daily recommended intake for adults. ### What is oligonol in dried lychee? Oligonol is a polyphenol compound formed during the drying process of lychee fruit. It consists of proanthocyanidin oligomers that have enhanced bioavailability compared to other flavonoids. ### Can dried lychee help with circulation? Studies suggest oligonol in dried lychee may improve blood flow by 20-25% through enhanced nitric oxide production. This effect typically appears after 4-6 weeks of regular consumption. ### Is dried lychee safe for diabetics? Dried lychee has a high glycemic index due to concentrated natural sugars. Diabetics should consume small portions and monitor blood glucose response carefully. ### How does dried lychee compare to fresh lychee nutritionally? Dried lychee contains 3-4 times more concentrated nutrients but loses some vitamin C during processing. The oligonol content actually increases during the drying process through oxidation. ### Is dried lychee safe for pregnant women and nursing mothers? Dried lychee is generally considered safe for pregnant and nursing women when consumed in normal dietary amounts due to its nutrient profile and historical use in traditional medicine. However, pregnant women should consult their healthcare provider before using dried lychee supplements, as concentrated forms may contain higher levels of bioactive compounds than whole fruit. Moderation is recommended, and dried lychee should not replace medical advice during pregnancy. ### Does dried lychee interact with blood thinners or anticoagulant medications? Dried lychee contains polyphenolic compounds that may have mild anticoagulant properties, so individuals taking blood thinners like warfarin or aspirin should consult their healthcare provider before supplementing. While normal dietary consumption is unlikely to cause significant interactions, concentrated supplements could potentially potentiate medication effects. A healthcare professional can assess individual risk based on dosage and medication type. ### What is the recommended daily serving of dried lychee as a supplement? Most studies on dried lychee extract use dosages ranging from 100–300 mg daily, though whole dried fruit consumption typically involves 10–30 grams per day mixed with other ingredients. Optimal dosage depends on the product form (whole fruit versus standardized extract) and individual health goals. Start with lower amounts and consult a healthcare provider to determine the appropriate dose for your specific needs. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
