Anecdotes on plants

Meanings of name The specific epithet chinense means Chinese in Latin, referring to its native distribution in China. Since the blades of its saplings are sometimes octagonal, it is also named as '八角楓'.
Application

Chinese Alangium is valued for its versatile medicinal functions. Its roots, leaves and flowers are the major sources of traditional Chinese medicines for promoting health. The roots contain venoterpine and dl-anabasine that can activate meridians and soothe sinew. The leaves are an excellent source of β-sitosterol and β-amyrin acetate which can relieve swelling and pain. Notably, despite of its great medicinal effects, it is poisonous and lethal when over-consumed. A Chinese man died from an overdose of the roots of Chinese Alangium.

Chinese Alangium’s wood is demanded for making boxes, chairs, and wardrobes. Its bark fibres are stiff enough for ropes.
