Cortex Phellodendri seeds Huang bai seeds
LATIN NAME: PHELLODENDRON AMURENSE
COMMON NAME: Amur Cork Tree, Huang Bai, Amur Corktree
The Amur cork tree is a handsome and stately tree of the cold forests, and it is the tree of the thick, soft, corky bark. It grows as a deciduous tree, reaching up to fifteen metres or more, with an upright, branching trunk bearing the thick, soft, deeply furrowed, corky, grey-brown bark and alternate, pinnate, oval, pointed, dark-green leaves and, in the late spring, small, greenish-yellow flowers, the male and the female on the separate trees, followed by the clusters of small, round, black fruits. It is a species of the flowering tree in the rue family, native to the cold forests of northeastern Asia, while it is grown for its fine, leafy crown, its remarkable bark and its long history of use in the traditional ways of the region, and it is known as the Amur cork tree.
Scientific Research & Plant Biotechnology
The Amur cork tree has a real and distinguished place in research. It has been studied in the chemistry of natural products and the traditional use, since the inner bark of the Amur cork tree has a very long history of use in the traditional medicine of China, and the researchers have examined the bark and its constituents, while the traditional uses of the tree have drawn attention in the international pharmaceutical and botanical press, and the study of the tree and its chemistry has been of continuing interest across the world, and the tree is best appreciated as a subject of study and of the tradition rather than a casual remedy. The plant has also been studied in the botany and the material science, since the Amur cork tree is remarkable for its thick, soft, corky bark, and the researchers have examined the bark, its cork and their uses, while the study of the cork-producing trees has been of continuing interest, and the fine, corky bark of the tree has been of value in the making of the light, buoyant articles. The species has also been studied in the forestry and the horticulture, since it is a handsome, stately tree of the cold garden, and the researchers have examined its growth and its cultivation, while its fine, pinnate foliage and its stately form have made it a treasured tree of the parks. For a tree of such stately value, the Amur cork tree has a rich and distinguished record of research.
Ecological & Economic Value & Wide Applications
To grow the Amur Cork Tree from seed, ecologically, the Amur cork tree is a generous tree of the garden. Its small, greenish-yellow flowers feed the bees and the insects, and its clusters of small, round, black fruits feed the birds, while its fine, pinnate, leafy crown gives a fine shade and a cover to the birds through the summer. Its economic value is real: the Amur cork tree is prized for its thick, soft, corky bark and its very long history of use in the traditional ways of China, and its value has drawn attention in the international pharmaceutical and botanical press, while the fine, corky bark has also been used in the making of the light, buoyant articles of the region. To raise the Amur cork tree, give the seeds a cold, damp spell, then sow them just below the surface of pots of gritty, free-draining compost, keep them lightly watered, and grow the little trees on in a shaded spot.

COMMON NAME: Amur Cork Tree
The Amur cork tree is a handsome, upright, deciduous tree of the temperate gardens, and its fine, pinnate foliage and its corky, furrowed bark have made it a valued tree of the parks and the avenues. It grows as a deciduous tree, reaching up to fifteen metres or more, with the upright, branching trunk bearing the thick, corky, deeply furrowed bark and the opposite, pinnate leaves of the many oval, pointed leaflets and, in the early summer, the small, greenish-yellow flowers, followed by the clusters of the small, black, berry-like fruits. It is a species of the flowering tree in the rue family, and it is native to the eastern Asia, while it is grown as an ornamental and a bark tree, and it is known as the Amur cork tree.

The plant has also been studied in the horticulture and the arboriculture, since it is a handsome, upright, deciduous tree of the park, and researchers have examined its growth, its hardiness and its cultivation, while the growing of the Amur cork tree in the garden has been of continuing interest, and its fine, pinnate foliage and its corky bark have been valued in the park. The species has also been studied in the botany and the ecology, since it is a native of the woodlands of the eastern Asia, and its distribution and its role in the forest have been examined, while the conservation and the planting of the tree has been of continuing interest, and the plant is best appreciated as a subject of study and of the garden rather than a casual remedy. For a tree of such quiet usefulness, the Amur cork tree has a rich and continuing record of study.
Ecological & Economic Value & Wide Applications
Ecologically, the Amur cork tree is a generous tree of the garden. Its small, greenish-yellow flowers feed the bees and the insects, and its clusters of the small, black, berry-like fruits feed the birds, while its fine, pinnate foliage gives a light, airy shade to the park.
Its economic value is real. The Amur cork tree is prized for its corky bark and its traditional uses, and its value has drawn attention in the international pharmaceutical and botanical press as a tree of the eastern Asia, while its thick, corky bark has also been valued in the making of the fine cork of the region. For a grower, the Amur cork tree is a rewarding and interesting tree, and for a gardener it brings a fine, pinnate, corky-barked tree to the garden. The seeds are easy to start — give them a short period of cold, damp storage in the fridge, then sow them just below the surface of a pot of moist, free-draining soil, keep them lightly watered, and theyll be sprouting steadily, growing on into a handsome, pinnate, corky-barked tree.

ACTION To remove damp-heat, quench fire, counteract toxicity, and relieve consumptive fever. Cortex Phellodendri(processed with salt) To nourish yin and reduce fire. INDICATIONS Dysentery, jaundice and morbid leucorrhea caused by damp-heat; urinary infectious; weakness and edema of legs; consumptive fever and night sweating; seminal emission; sores and skin infection with local redness and swelling; eczema with itching.
Cortex Phellodendri(processed with salt): Night sweating and consumptive fever due to exuberant fire secondary to deficiency of yin. REFERENTIAL ADVICE 1.Reducing heat and resolving dampness:
For the treatment of dysentery due to damp-heat accompanied with fever and tenesmus, it is often combined with Radix Pulsatillae, Cortex Fraxini, etc.; for jaundice with fever due to damp-heat, with Fructus Gardeniae and others for recuding heat and resolving dampness; for yellow and thick leukorrhea due to damp-heat with Semen Euryales, Semen Ginkgo, etc.; for the treatment of the low extremities affected with hotness and pain due to the descending of damp-heat, with Rhizoma Atractylodis, Radix Achyranthis Bidentatae; for stranguria with hot sensation or painful urination with dark urine, with Fructus Gardeniae, Semen Plantaginis, etc.
2.Purging fire and eliminating virulent evil factors:
For the treatment of eczema and skin pyogenic infection due to virulent heat, it may be used internally or externally: for eczema, it can be used with Herba Schizonepetae, Radix Sophorae Flavescentis; for skin pyogenic infection, it can be used internally in combination with Rhizoma Coptidis, Fructus Gardeniae, etc. and used externally by mixing its powder with pig's bile.
3.Eliminating asthenia-heat:
For the treatment of hectic fever, nocturnal emmision, night sweating, due to deficiency of Yin leading to flare-up of fire, it is often combined with Rhizoma Anemarrhenae.
