Horse Chestnut

Aesculus hippocastanum

Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: The raw seed is toxic (presence of esculin) and must never be consumed as is or prepared at home without specific expertise: only standardized extracts prepared by professionals are traditionally used internally. Not recommended for pregnant or breastfeeding women, or for children, in the absence of sufficient data. Avoid in case of bleeding disorders or in combination with anticoagulant treatments, due to possible interactions. Internal use must be supervised by a healthcare professional or qualified herbalist; do not attempt preparation with raw seeds.

Tincture (supervised use) — Seeds (chestnuts)

Horse chestnut tincture for external use

Fresh seeds, once removed from their shell, can be macerated in alcohol to obtain a tincture intended for local rubbing on the legs. This preparation requires particular expertise and is more safely obtained already prepared from an herbalist. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Decoction — Bark of young branches

Bark decoction for external use

Dried bark was traditionally decocted and then applied as warm compresses on areas to be relieved. This preparation is reserved for external use and should be consulted with a professional for any potential internal use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Infused oil — Crushed seeds

Horse chestnut oil for gentle massage

Crushed and dried seeds can be cold-infused in vegetable oil for several weeks, then filtered, to obtain a massage oil intended for tired legs, for external application only. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Obtaining the plant

Horse chestnut is found in parks, avenues, and public gardens throughout Europe; its standardized extracts, however, are obtained from herbalists or pharmacies in the form of dosed preparations.
