Some parts of the birch plant are edible and medicinal
Birch toxic to humans?
Birch trees are one of those special types of trees that are even edible - some parts, of course. The leaf of the birch, for example, can be used to make tea. Due to the flavonoids, essential oils and vitamins it contains, eating birch leaves can contribute to a healthy diet and combat various symptoms of illness.
The same applies to birch buds: You can also consume these pure or brew them into a tea with a slightly woody aroma. Birch sap and birch sugar are also well-known edible birch products that can be used positively by the body. In this respect, the tree does not contain any substances that are toxic to humans.
animals and birches
Since birch extracts have a strong dehydrating effect, caution should be exercised with some animals. Although there is no question of a toxic effect here either, some pets feel less well after nibbling on birch leaves or the bark. These include, in particular, budgerigars. Basically, there is nothing to be said against consumption in moderation, but also for birds or horses.
