Horse chestnut seed extract is one of the most clinically validated herbs for chronic venous insufficiency, varicose veins, and haemorrhoids. Its aescin saponins reduce capillary permeability, improve vascular tone, reduce fluid leakage into tissues, and exert anti-inflammatory action. European Commission-approved for chronic venous insufficiency, it has a strong evidence base in randomised trials.

Raw horse chestnut is toxic — only standardised, processed extracts are safe for internal use. Aescin may increase anticoagulant effect — monitor with blood thinners. May irritate GI tract — take with food. Avoid in kidney or liver disease.
