# Dried Thimbleberry **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/dried-thimbleberry **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-18 **Evidence Score:** 4 / 10 **Category:** Fruit **Also Known As:** Rubus parviflorus, Red Thimbleberry, White Flowering Raspberry, Salmonberry, Western Thimbleberry, Mountain Sorrel Berry, Nutkana ## Overview Dried thimbleberry contains high concentrations of vitamin C and tannins that support immune function and [digestive health](/ingredients/condition/gut-health). The tannins reduce gut [inflammation](/ingredients/condition/inflammation) while vitamin C stimulates [white blood cell](/ingredients/condition/immune-support) production for enhanced pathogen resistance. ## Health Benefits - High in vitamin C, dried thimbleberry boosts immune function by stimulating [white blood cell](/ingredients/condition/immune-support) production. This helps the body fend off infections more effectively. - Contains tannins, which may support [digestive health](/ingredients/condition/gut-health) by reducing inflammation in the gut lining. This can alleviate symptoms of gastrointestinal disorders. - Rich in antioxidants, it combats [oxidative stress](/ingredients/condition/antioxidant), potentially lowering the risk of chronic diseases. Antioxidants neutralize free radicals, protecting cells from damage. - Provides dietary fiber, which aids in maintaining regular bowel movements. Fiber also supports a healthy gut microbiome by feeding beneficial bacteria. - Contains ellagic acid, known for its [anti-inflammatory](/ingredients/condition/inflammation) properties, which can reduce the risk of chronic inflammation-related conditions. - Offers manganese, a mineral that supports [bone health](/ingredients/condition/bone-health) and [metabolism](/ingredients/condition/weight-management). Manganese is crucial for bone formation and nutrient absorption. - Contains polyphenols, which may improve [cardiovascular health](/ingredients/condition/heart-health) by enhancing blood vessel function. Polyphenols help maintain healthy blood pressure levels. ## Mechanism of Action Vitamin C in dried thimbleberry enhances [immune function](/ingredients/condition/immune-support) by stimulating neutrophil chemotaxis and supporting T-cell proliferation through [collagen synthesis](/ingredients/condition/skin-health) pathways. The tannin compounds, particularly ellagitannins, bind to proteins in the gut mucosa and reduce [inflammatory](/ingredients/condition/inflammation) cytokine production via NF-κB pathway inhibition. ## Clinical Summary Limited clinical research exists specifically on dried thimbleberry, with most evidence extrapolated from fresh berry studies. Small observational studies (n=20-40) on related Rubus species suggest potential [anti-inflammatory](/ingredients/condition/inflammation) effects, but controlled trials are lacking. Current evidence is primarily based on in vitro studies of individual compounds rather than whole fruit preparations. More rigorous human trials are needed to establish therapeutic efficacy. ## Nutritional Profile - High in vitamin C and fiber. - Contains [antioxidant](/ingredients/condition/antioxidant)s and tannins. - Low in calories and fat. ## Dosage & Preparation Consume 15-25 grams daily. Consult a healthcare provider before use. ## Safety & Drug Interactions Dried thimbleberry is generally safe for most adults when consumed in typical food amounts. High doses may cause gastrointestinal upset due to tannin content. No significant drug interactions are documented, though the vitamin C content may enhance iron absorption. Pregnant and breastfeeding women should limit intake to normal dietary amounts due to insufficient safety data. ## Scientific Research Preliminary studies suggest thimbleberries have high [antioxidant](/ingredients/condition/antioxidant) content, which may contribute to their health benefits. Further research is needed to confirm these effects. ## Historical & Cultural Context Thimbleberries have been used by Native American tribes for both culinary and medicinal purposes. They are often found in wild foraging expeditions. ## Synergistic Combinations Cranberries, Raspberries, Strawberries ## Frequently Asked Questions ### How much vitamin C is in dried thimbleberry? Dried thimbleberry contains approximately 25-40mg of vitamin C per ounce, which is about 28-44% of the daily recommended intake. The drying process reduces vitamin C content by roughly 60% compared to fresh berries. ### Can dried thimbleberry help with digestive issues? The tannins in dried thimbleberry may help reduce gut inflammation and support digestive health. However, consuming large amounts may cause stomach irritation in sensitive individuals due to the astringent properties of tannins. ### What's the recommended daily dosage of dried thimbleberry? No official dosage guidelines exist for dried thimbleberry supplements. As a food, 1-2 ounces daily is considered safe for most adults, providing beneficial nutrients without excessive tannin intake. ### Does dried thimbleberry interact with blood thinners? No documented interactions exist between dried thimbleberry and anticoagulant medications. However, the vitamin C content may slightly enhance iron absorption, so individuals on specific mineral therapies should consult healthcare providers. ### Is dried thimbleberry safe during pregnancy? Dried thimbleberry in normal food amounts appears safe during pregnancy, providing vitamin C and antioxidants. However, medicinal doses should be avoided due to limited safety research, and pregnant women should consult their healthcare provider before regular supplementation. ### What is the difference between dried thimbleberry and fresh thimbleberry? Dried thimbleberry concentrates the nutrient density, including vitamin C and antioxidants, making it more potent per gram than fresh berries. The drying process removes water content but preserves most beneficial compounds like tannins and polyphenols. Dried thimbleberry also has a longer shelf life and is easier to incorporate into supplements compared to fresh berries, which are highly perishable. ### Who should consider taking dried thimbleberry supplements? Individuals with weakened immune systems, those prone to frequent infections, and people seeking natural antioxidant support may benefit most from dried thimbleberry supplementation. It is also suitable for those experiencing mild gastrointestinal inflammation or oxidative stress-related concerns. However, those on blood-thinning medications or with allergies to berries should consult a healthcare provider before use. ### What does research show about dried thimbleberry's antioxidant effectiveness? Clinical studies indicate that thimbleberry's high polyphenol and flavonoid content effectively combats oxidative stress, potentially reducing markers of inflammation and cellular damage. The antioxidant capacity is comparable to other nutrient-dense berries, though human clinical trials specifically on dried thimbleberry remain limited. Most evidence comes from laboratory and animal studies, suggesting further research is needed to confirm long-term antioxidant benefits in humans. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
