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.
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).
Bacopa monnieri (Brahmi) extract and its saponins (bacopaside II, bacopasaponins) inhibit proliferation and induce apoptosis in colon and lung cancer cells (preclinical).
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
inferred from anti-inflammatory action
Bacopaside II from Bacopa monnieri inhibits colon cancer cell growth via cell-cycle arrest and apoptosis (aquaporin-1 blockade), and its bacopasaponins are cytotoxic to lung (PC9) and colon (SW620) cancer cells (preclinical).

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.
Generally well tolerated at standard doses. The most commonly reported side effects are gastrointestinal — nausea, stomach cramps, and increased bowel movements — which can be reduced by taking with food. Not recommended during pregnancy. May interact with medications that increase acetylcholine levels (e.g. Alzheimer's medications). Use with caution in thyroid conditions, as bacopa may increase thyroid hormone levels.

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, creeping, succulent perennial herb that roots at the nodes as it spreads across wet ground. The leaves are small, fleshy, spatula-shaped and arranged oppositely along the trailing stems. Small, pale lavender to white, four- to five-petalled flowers are borne singly in the leaf axils.[4]
Habitat
Native to the Balkan Peninsula, and widely planted and naturalised as an ornamental and avenue tree across temperate Europe, North America and elsewhere.[1]
Grows in wet, marshy ground, muddy shorelines, rice paddies and shallow water throughout tropical and subtropical regions of Asia, and also found in parts of Africa, Australia and the Americas.[4]
Harvesting
The whole plant (leaf and trailing stem) is harvested during active growth, typically cut a few centimetres above the mud or water line, and dried or used fresh.
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]
Bacopa (brahmi) is a classic Ayurvedic 'medhya rasayana' (brain-nourishing) herb, traditionally used to support memory, learning and mental clarity, and as a calming nervine for anxiety and disturbed sleep. This traditional cognitive reputation is now supported by randomised controlled trials of standardised extracts.[1, 4]
Preparations
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.
