Safety Overview
1.Chinese Magnolia — Overview
Chinese Magnolia, scientifically known as Magnolia officinalis, is a distinguished deciduous tree belonging to the ancient Magnoliaceae family. Native to the mountainous regions and forests of central and southern China, particularly prevalent in areas like Sichuan, this species can reach impressive heights of up to 20 meters. Its morphology is characterized by a thick, grey-brown bark, which is the primary part utilized in traditional medicine. The bark often displays oval lenticels and longitudinal striations, becoming purplish-brown or dark brown upon traditional processing.
The leaves are large, simple, and obovate to elliptic, typically dark green and glossy. In spring, the tree produces large, fragrant, cup-shaped white or creamy-white flowers, which are highly ornamental and contribute to its common appeal. These blossoms later give way to cone-like fruits containing bright red seeds. Historically, Magnolia officinalis, known as 'Houpo' in Traditional Chinese Medicine (TCM), has been a cornerstone of Asian herbal pharmacopoeias for thousands of years.
Its earliest recorded use dates back to at least 200 AD, where it was documented in classic texts like the 'Shennong Ben Cao Jing'. The plant's significance extends beyond TCM to Japanese Kampo medicine, where its bark and flower buds (Houpohua) are integral components of numerous traditional formulas. This enduring legacy underscores its profound cultural and medicinal value, cementing its status as a vital botanical resource. Modern research continues to explore and validate the therapeutic potential that has been recognized by generations of practitioners, particularly focusing on the unique bioactive compounds present in its bark.
