How to Make Horse Chestnut Extract Aescin(Escin) Powder?

The extraction process for our horse chestnut seed extract is as follows: starting with crushed horse chestnut seeds as raw material, we perform triple cycle extractions using 60% ethanol. The extract is then filtered to remove impurities, after which the combined filtrate is concentrated in a vacuum evaporator for 48 hours. Next, the target components are enriched via extraction; if precipitation occurs, the precipitate is collected directly, while if no precipitate forms, further concentration is carried out to induce precipitation. Finally, the precipitate is concentrated again in a vacuum evaporator for 24 hours to obtain the final product.

Horse Chestnut Extract  Aescin(Escin) Benefits

Horse chestnut extract for varicose veins

Aescin, the core active component of horse chestnut seed extract, exerts a significant improvement effect on both varicose veins and spider veins.

On one hand, it enhances the tension of venous vessel walls, reduces vascular fragility, and promotes venous blood reflux, effectively alleviating venous blood stasis, thus mitigating the red fine streaks of spider veins and the distension and protrusion of varicose vessels.

 On the other hand, it can inhibit hyaluronidase activity, reduce capillary wall permeability and prevent plasma protein extravasation, thereby relieving the lower limb swelling, heaviness and pain caused by varicose veins and spider veins; meanwhile, it improves local lymphatic circulation, accelerates the discharge of metabolic waste, and further alleviates the discomfort brought by such venous problems.
