Birch Tree: Source Plant Introduction, Distribution, and Growth Environment

The birch tree (scientific name: Betula platyphylla), also known as white birch, is a common deciduous tree belonging to the Betulaceae family. Below is the introduction of the source plant for birch leaf extract, its distribution, and growth environment:

Source Plant:
Birch trees are common and widely distributed around the world, particularly in temperate and cold regions. Their main characteristics include grayish-white or gray-brown bark with a clear texture, heart-shaped or oval leaves with obvious serrated edges. Birch trees are known for their resilience and adaptability, often growing in various soil types including riverbanks, hillsides, and wetlands.

Distribution:
Birch trees are predominantly found in the temperate and boreal regions of the Northern Hemisphere, mainly concentrated in Europe, North America, Asia, and North Africa. In Europe, birch trees are primarily distributed in countries of Northern, Eastern, and Western Europe, such as Finland, Sweden, Norway, and Russia. In North America, their range includes Canada, the United States, and Mexico. In Asia, birch trees are mainly found in China, Japan, South Korea, and Mongolia. Additionally, birches also grow in some North African countries like Morocco and Algeria.

Growth Environment:
Birch trees are highly adaptable, capable of thriving in various soil and environmental conditions, although they prefer moist, fertile soil. They are commonly found in mountainous areas, along riverbanks, near lakes, and in boreal and temperate coniferous and mixed forests. Birch trees require ample sunlight but can also tolerate shady conditions. With a well-developed root system, they are cold-resistant and drought-tolerant, making them a resilient tree species.

In summary, as the source plant for birch leaf extract, birch trees have a wide growing range, distributed throughout the temperate and boreal regions of the Northern Hemisphere, typically thriving in moist, fertile soil, and are a significant plant resource.

Processing and Storage of Birch Leaf Extract

The processing of birch leaf extract generally includes the following steps: First, collect fresh birch leaves and perform preliminary washing to remove impurities; next, dry the cleaned birch leaves to remove moisture; then, use appropriate extraction methods (such as water or alcohol extraction) to obtain active components from the leaves; finally, the extracted materials undergo filtration, concentration, drying, etc., to produce birch leaf extract.

In terms of storage, birch leaf extract should be kept in a dry, cool, and ventilated environment, away from direct sunlight and high temperatures. Further, it should be protected from harmful gases and odorous substances to preserve quality. During storage, periodic checks on the appearance and smell of the extract are advisable to ensure no abnormal changes occur.
