Horse Chestnut Extract (Aesculus hippocastanum) comes from the konker tree, a type of flowering tree in the soapberry family (Sapindaceae) that is native to a small region in Southeastern Europe. Today, Horse chestnut trees can be found throughout the world and are common in temperate climates. They can grow to around 128 ft tall and develop white flowers in the spring. Horse Chestnut trees develop small, spiny, green fruits with a large seed in the middle (often called konkers). The seed is similar in appearance to chestnuts.
