Wild vegetables, wild fruits, useful and medicinal herbs, nourishing trees, or mushrooms grow right at your doorstep. Today, only a few people are aware of the value, processing, and uses of these plants, even though once widely practiced methods of utilization have gained more popularity in recent years. The PhD botanist Michael Machatschek documents in his books the locations, preparation methods, as well as the nutritional and healing functions of plants, along with general rules for sustainable land use. The focus of the third volume in the "Nourishing Landscape" series is on Central European herb species such as foam and spring herbs, sweet acorns, or ear mushrooms, and the possibilities of processing tree sap. The author explains how and when to tap water from trees, that birch sap can be consumed fresh or fermented, and that when used correctly, it has detoxifying effects.
