European chestnut tree (scientific name: Aesculus hippocastanum L.). Deciduous trees, distributed in deciduous woodlands of Europe. One of the four largest trees in the world. The tree is tall and stately, with broad canopy, dense green shade and beautiful inflorescence. It is widely used as a roadside tree and garden ornamental tree in Europe and America. Its extract has strong effect to eliminate edema, and it is effective for the treatment of varicose.
The tree can protect the vascular and structural integrity of the arteries, improve the function of the veins, and take into account the multiple effects of anti-inflammatory and antioxidation. With the further development of the study, the leaves inhibit the collagenase, hyaluronidase, B glucosidase, and elastic enzymes (which catalyze the integrity of the broken veins and the capillaries. " The effect of exudation is also confirmed); in external use, it can promote blood circulation, promote wound healing, anti edema, anti inflammatory and anti exudation and vascular protection (black eye, red blood silk, anti wrinkle, repair). Seven leaf element is the most important ingredient in the fruit of the seven leaf tree. It can effectively improve the integrity of vascular wall by filling small gaps and tiny gaps in the small veins and capillaries, so the tree can help to repair the capillaries.
