The Bach flower Aspen is composed of aqueous extracts of Populus tremula and Brandy. Behind this scientific name lies, in fact, a tree relatively widespread in Europe, but also in North America and North Asia: the aspen. This tree, belonging to the large Salicaceae family, particularly appreciates environments bathed in sunlight. This is why it is more easily found in plains and clearings than in undergrowth. Its natural resistance even allows it to grow at medium altitudes.
Botanically, the aspen, sometimes nicknamed "trémou" or "trémolin," reaches a height of between 20 and 30 meters. Its trunk and branches are covered with smooth bark on which lenticels form, here and there, in diamond-shaped patterns. It is this bark that has medicinal properties that have been used for centuries. Its leaves are characterized by their rounded and serrated shapes. In autumn, they take on a particularly sublime golden color. It is to them that the tree owes its particular name, because they tremble at the slightest breath of air, as if calling for comfort. The tree's flowers, for their part, are grouped in catkins that develop in spring.
