Magnolia bark extract
Magnolia bark is a popular herb in traditional Chinese and Japanese medicine. Modern research shows that it's helpful when treating various conditions like stress-induced anxiety, digestive issues, and sleep troubles among others.
Today, magnolia bark extract is used all over the world and forms a key ingredient in many beauty products and food supplements.
As you might have gathered from its name, magnolia bark refers to the bark of the magnolia tree — a native of East and Southeast Asia. This tree belongs to the Magnoliaceae family and can grow to a mature height from 16 ft up to 80 ft. You can easily identify the magnolia tree from its large and fragrant flowers that often reach 8 inches in diameter. Along with the bark, sometimes these flowers and leaves are also used for making medicine.
The scientific name of magnolia bark is Magnolia officinalis. The Chinese also call this herb "Houpu" — referring to the thick (hou) bark that comes from the unadorned (pu) part of the tree. Its other names are magnolia cortex, cucumber tree, honoki, and swamp sassafras.
Those who practice traditional Chinese medicine (TCM) often harvest the bark in April and June. They do it by peeling or cutting the bark from the roots, stems, and branches of the tree. While the stem barks are decocted to a slight extent in boiling water, the branch and root barks are dried in the shade. All these barks are then stacked up in a wet area. Once their inner surface turns dark brown or purplish brown, the TCM practitioners steam, roll, and dry them.
