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 dominant bioactive class, driving much of the antioxidant and anti-inflammatory activity.
Studied for immunomodulatory, hepatoprotective and gut-microbiota-modulating effects.
Concentrated in the hips, underpinning their traditional food-tonic use.
Isolated from the root and studied for antioxidant/neuroprotective activity.
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

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 safe as a food plant. Rose hips should be used after removing the achenes (seeds and inner hairs), which can cause irritation. Allergic reactions are rare. No significant drug interactions documented.

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]
Dense, thicket-forming deciduous shrub (Rosaceae), 1-1.5 m tall (occasionally to 2 m), with stems densely covered in numerous straight, bristly thorns. Leaves are pinnate with 5-9 deeply veined, glossy, leathery leaflets. Large, fragrant, deep pink to white, five-petalled flowers are followed by large, tomato-red, flattened-globose hips.[2]
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]
Native to coastal eastern Asia (Japan, Korea, China, far-eastern Russia), typically growing on sand dunes and coastal scrub. Widely planted and naturalised as an ornamental and hedging shrub, notably tolerant of salt spray, wind and poor sandy soils, in temperate coastal regions worldwide.[2]
Harvesting
Flowers/petals are picked as they open in summer; hips are picked in autumn once fully coloured and slightly softened.[2]
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]
Rosa rugosa has a long East Asian tradition - particularly in Traditional Chinese Medicine, where the flower is known as 'Mei Gui Hua' - as a mood-regulating, digestive and menstrual-cycle-supporting remedy, and the vitamin-C-rich hips are used as a food tonic. Modern research on its flavonoid- and polysaccharide-rich extracts supports broad antioxidant, anti-inflammatory, hepatoprotective and immunomodulatory activity.[2]
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.
Traditional guidance suggests roughly 3-6 g dried flower per cup as an infusion, or hip tea/syrup at similar strength, taken once or twice daily. Educational reference only, not a prescription.
