Key Constituents
The active mixture responsible for the venotonic and anti-oedematous effects; extracts are standardised to it. Escin is available as oral drages and a transdermal gel, with efficacy shown in chronic venous insufficiency and blunt-trauma injury.
The deep blue-purple pigments; the principal antioxidant constituents.
Contribute to antioxidant and astringent activity.
Minor nutritive constituents of the berry.
Pharmacological Actions
Anti-oedematous and anti-inflammatory - escin reduces vascular permeability in inflamed tissue and exerts venotonic effects on veins
Anti-oedematous and anti-inflammatory - escin reduces vascular permeability in inflamed tissue and exerts venotonic effects on veins
Escin, the triterpene saponin of Aesculus hippocastanum, induces apoptosis and cell-cycle arrest and chemosensitizes breast, hepatocellular, lung and pancreatic cancer cells (preclinical, including in vivo xenograft models).
Traditional & Indicated Uses
inferred from anti-inflammatory action
Escin shows antiproliferative and pro-apoptotic activity and enhances chemotherapy/immunotherapy efficacy in breast (MCF-7), hepatocellular, lung and pancreatic cancer models; it modulates NF-kappaB, p53, p38 MAPK/ERK and PD-L1 (preclinical).
Relief of haemorrhoid symptoms (venotonic)
inferred from anti-inflammatory action
Chronic venous insufficiency - reduces leg pain, swelling (oedema), heaviness and itching; supports varicose veins
inferred from anti-inflammatory action
Chronic venous insufficiency - reduces leg pain, swelling (oedema), heaviness and itching; supports varicose veins

Supports cardiovascular and metabolic risk factors, including blood lipids (high cholesterol)
Traditional support for eye strain and vision (note: rigorous trials do NOT support improved night vision in healthy eyes)

inferred from venotonic action
Supports capillary integrity and venous tone (traditional use for varicose veins / chronic venous insufficiency)
Safety, Cautions & Contraindications
Use only standardised, processed seed extract. Raw conkers, leaves and bark contain toxic esculin and can cause poisoning - never eat raw horse chestnut.
May increase bleeding risk, so use caution with anticoagulant/antiplatelet medicines; use caution in kidney disease and avoid in pregnancy and breastfeeding.
The berry is a food and generally very safe; long-term safety of concentrated high-dose extracts is less well characterised.
May lower blood sugar and has mild antiplatelet potential, so use cautiously alongside antidiabetic or anticoagulant/antiplatelet medication.
Claims that bilberry improves night vision in people with normal sight are not supported by rigorous clinical trials.
External Ids
Botanical Description
Large deciduous tree, to 25-30 m, with a broad domed crown and stout, upward-arching branches. The leaves are opposite and palmately compound, with five to seven large, obovate, toothed leaflets radiating from a long stalk. In spring the tree bears large, showy, upright pyramidal flower spikes ('candles') of white flowers marked with yellow or pink at the base. The glossy brown seeds ('conkers') develop inside a spiky green husk and fall in autumn.[1]
Low, deciduous, much-branched shrub with sharply angled green stems and small, oval, finely toothed leaves. Small, pinkish-green, globe-shaped flowers are borne singly or in pairs, giving way to single, dark blue-black berries with a distinctive crowned top.[1]
Habitat
Harvesting
Berries are hand-picked or gathered with a berry rake when fully ripe in mid-to-late summer.
Traditional Uses
Horse chestnut seed has a long folk history as a remedy for varicose veins, haemorrhoids and 'heavy legs', and was also used topically for rheumatic pain and bruising. Modern use is almost exclusively as a standardised seed extract for chronic venous insufficiency, confirming this traditional venous-support reputation.[1]
Bilberry has a long European folk tradition as a food and remedy for diarrhoea, eye strain and circulatory complaints, with dried berry and standardized anthocyanin extracts studied for cardiovascular and metabolic support; claims of improved night vision in people with normal eyesight are not supported by rigorous clinical trials.[1, 14]
Preparations
Standardized anthocyanoside extract (commonly 25% anthocyanosides), used in circulatory and eye-health research.
Dosage
Clinical studies commonly use extracts standardised to around 100-150 mg escin daily, in divided doses. Educational reference only, not a prescription.
The EU herbal monograph gives semi-solid dosage forms containing the equivalent of 0.4% triterpene glycosides calculated as protoaescigenin (or, depending on the preparation, 0.85-20% herbal preparation), applied as a thin layer to the affected area 1-3 times daily, in adults and elderly. Educational reference only, not a prescription.
Clinical research commonly uses around 160-480 mg of standardized 25% anthocyanoside extract daily. Educational reference only, not a prescription.
