Last Updated: April 3, 2026 | Reviewed by the HemRid Medical Team
Our Commitment to Evidence-Based Formulation
At HemRid, we believe that effective hemorrhoid relief should be grounded in science — not marketing hype. Every ingredient in our formulas has been selected based on published clinical research and traditional use supported by modern evidence. Below, we share the research behind our key ingredients so you can make an informed decision about your health.
Important: HemRid supplements are not intended to diagnose, treat, cure, or prevent any disease. The studies referenced below examined individual ingredients, not the HemRid formula specifically. Always consult your healthcare provider before starting any supplement.
Horse Chestnut Seeds (20% Extract)
What it is: An extract from the seeds of Aesculus hippocastanum, standardized to 20% aescin. Used in traditional European medicine for centuries and one of the most well-researched botanicals for venous health.
Clinical Research:
- Pittler MH, Ernst E. (2012) — "Horse chestnut seed extract for chronic venous insufficiency." Published in Cochrane Database of Systematic Reviews. Systematic review of 17 trials concluded that horse chestnut seed extract significantly improved symptoms of chronic venous insufficiency including leg pain, edema, and itching. PubMed Link
- Sirtori CR. (2001) — "Aescin: pharmacology, pharmacokinetics and therapeutic profile." Published in Pharmacological Research. Comprehensive review of aescin's anti-inflammatory, venotonic, and anti-edema properties. PubMed Link
How HemRid uses it: Horse Chestnut Extract (standardized to 20% aescin) is a primary active ingredient in HemRid Max, supporting vein wall integrity and helping reduce swelling associated with hemorrhoids.
Witch Hazel Powder (Leaf, Stem and Twig)
What it is: A plant native to North America (Hamamelis virginiana) with a long history of use by Native Americans and in Western herbalism. Known for its astringent and anti-inflammatory properties.
Clinical Research:
- Wolff HH, Kieser M. (2007) — "Hamamelis in children with skin disorders and skin injuries." Published in Arzneimittelforschung (Drug Research). Demonstrated witch hazel's anti-inflammatory and skin-soothing properties. PubMed Link
- European Medicines Agency (EMA) — "Assessment report on Hamamelis virginiana L." The EMA recognizes witch hazel for traditional use in minor skin inflammation and hemorrhoid symptom management. EMA Link
How HemRid uses it: Witch Hazel Powder (from leaf, stem, and twig) is included in HemRid Max as a natural astringent to help soothe irritated tissue and reduce inflammation from within.
Hesperidin (from Citrus Peels)
What it is: A citrus bioflavonoid naturally found in orange and lemon peels. Hesperidin is one of the most widely studied flavonoids for vascular health and is a key component of the "micronized purified flavonoid fraction" used extensively in hemorrhoid research.
Clinical Research:
- Perera N, et al. (2012) — "Phlebotonics for haemorrhoids." Published in Cochrane Database of Systematic Reviews. Meta-analysis of 24 trials (2,344 patients) concluded that phlebotonics containing flavonoids (including hesperidin) showed significant benefits for itching, bleeding, discharge, and overall symptom improvement. PubMed Link
- Garg A, et al. (2001) — "Chemistry and pharmacology of the citrus bioflavonoid hesperidin." Published in Phytotherapy Research. Review of hesperidin's anti-inflammatory, antioxidant, and vascular-protective properties. PubMed Link
How HemRid uses it: Hesperidin from citrus peels is included in HemRid Max to support vascular health and complement the formula's other bioflavonoid ingredients.
Bilberry Fruit (4:1 Extract)
What it is: A concentrated extract from Vaccinium myrtillus (European blueberry), rich in anthocyanins — powerful antioxidants studied for their effects on blood vessel health and microcirculation.
Clinical Research:
- Ulbricht C, et al. (2009) — "An evidence-based systematic review of bilberry by the Natural Standard Research Collaboration." Published in Journal of Dietary Supplements. Reviewed evidence for bilberry's role in supporting microcirculation and vascular integrity. PubMed Link
How HemRid uses it: Bilberry Fruit Extract (4:1 concentration) supports healthy microcirculation and provides antioxidant protection for blood vessels, complementing the vein-strengthening effects of Horse Chestnut and Hesperidin.
Butcher's Broom Root Powder
What it is: A root extract from Ruscus aculeatus, a plant native to the Mediterranean region. Butcher's Broom has been used for centuries in traditional European medicine for circulatory concerns and is recognized by the European Medicines Agency.
Clinical Research:
- Vanscheidt W, et al. (2002) — "Efficacy and safety of a Butcher's Broom preparation for chronic venous insufficiency." Published in Arzneimittelforschung. Demonstrated significant improvement in venous symptoms. PubMed Link
- European Medicines Agency (EMA) — Recognizes Butcher's Broom for traditional use in relief of discomfort and heaviness related to chronic venous insufficiency. EMA Link
How HemRid uses it: Butcher's Broom Root Powder supports venous tone and helps reduce the pooling of blood that contributes to hemorrhoid development.
Enovita (Grape Seed Extract, ≥95% Proanthocyanidins)
What it is: A premium grape seed extract standardized to contain at least 95% proanthocyanidins — powerful antioxidant compounds that support blood vessel strength and elasticity.
Clinical Research:
- Belcaro G, et al. (2015) — "Grape seed procyanidins in venous conditions." Published in Angiology. Demonstrated that grape seed proanthocyanidins significantly improved venous function and reduced edema. PubMed Link
How HemRid uses it: Enovita Grape Seed Extract provides concentrated proanthocyanidins that support blood vessel strength and elasticity, working synergistically with the formula's other vascular support ingredients.
Vitamin C (Ascorbic Acid)
What it is: An essential vitamin critical for collagen synthesis — the protein that gives structure and strength to blood vessel walls. Vitamin C is also a potent antioxidant that protects tissues from oxidative stress.
Clinical Research:
- Vitamin C's role in collagen synthesis and vascular health is extensively documented across thousands of peer-reviewed studies. It is essential for maintaining the structural integrity of blood vessels, including the veins affected by hemorrhoids.
How HemRid uses it: Vitamin C is included to support collagen production and help maintain the strength of blood vessel walls that become weakened in hemorrhoid conditions.
