Cortex Meliae(Szechwan Chinaberry Bark).
Brief Introduction: The Herb Cortex Meliae is the dried stem-bark or root-bark of Melia toosendan Sieb.et Zucc., or Melia azedarach L.(family Meliaceae), used as an antiparasitic for the treatment of helminths, and externally for scabies. The herb is commonly known as Cortex Meliae, Szechwan Chinaberry Bark, Kǔ Liàn Pí.
✵The common official herbal classics and other famous herbal classics defined the herb Cortex Meliae(Szechwan Chinaberry Bark) as the dried stem-bark or root-bark(cortex) of species (1).Melia toosendan Sieb.et Zucc., or (2).Melia azedarach L. They are plant species of the Melia Linn genus, the Meliaceae family of the Rutales order. These 2 commonly used species are introduced as:
(1).Melia toosendan Sieb.et Zucc.: It is commonly known as Chuān Liàn. Trees, more than 10 meters high; Young branches densely covered with brown stellate scales, none when old, dark red, lenticellate, leaf markings conspicuous. 2 gyri feathery compound leaf length 35-45 cm, each feather has 4-5 pairs of lobules; With a long handle; Leaflets opposite, shortly sessile or subsessile, membranous, elliptic-lanceolate, 4-10 cm long, 2-4.5 cm wide, apex acuminate, base cuneate or subrounded, both surfaces glabrous, entire or with inconspicuous obtuse teeth, lateral veins 12-14 pairs. Panicles clustered in leaf axils on top of branchlets, about 1/2 the length of a leaf, densely covered with grayish-brown stellate scales; Flowers pedicellate, denser; Sepals oblong to lanceolate, ca. 3 mm long, both surfaces pilose, outer denser; Petals mauve, spatulate, 9-13 mm long, sparsely pilose outside; Stamen tube terete, purple, glabrous and veined, apex with 10 3-lobed teeth, anthers oblong, glabrous, ca. 1.5 mm long, slightly protruding from tube; Disk subcupped; Ovary subglobose, glabrous, 6-8 locules, style subterete, glabrous, stigma inconspicuously 6-toothed, enclosed in staminal tube. Drupes large, elliptic, spherical, about 3 cm long, about 2.5 cm wide, peel thin, yellow when cooked; Nucleus slightly harder, 6-8 cells. Flowering from March to April, fruiting from October to November.
Ecological environment: It grows in miscellaneous wood forests and thin forests at an altitude of 500-2,100 m, or in flat DAMS and moist hilly areas. It is often cultivated near the village or along the highway in the miscellaneous wood and thin forest or the flat dam and hilly area. Distributed in Gansu, Henan, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan and other areas of China.
It prefers warm and humid climate, sunny and not shaded. It can grow in areas which altitude is below 1000 m above sea level. Better choose where sufficient sunshine, deep soil layer, loose fertile sandy soil for cultivation.
(2).Melia azedarach L.: It is commonly known as Liàn. Deciduous trees, up to more than 10 meters; Bark grayish brown, longitudinally lobed. Branches broad, branchlets with leaf markings. Leaves 2-3 odd-pinnate compound, 20-40 cm long; Leaflets opposite, ovate, elliptic to lanceolate, apex one usually slightly larger, 3-7 cm long, 2-3 cm wide, apex short acuminate, base cuneate or broadly cuneate, somewhat oblique, margin stellate hairy when young, posterior both surfaces glabrous, lateral veins 12-16 on each side, widely spreading, ascending oblique. Panicles ca. Leaf length, glabrous or scaly pubescent when young; Flowers fragrant; Calyx 5-lobed, lobes ovate or oblong-ovate, apex acute, outside puberulent; Petals mauve, obovate-spatulate, ca. 1 cm long, puberulent on both sides, usually dense outside; Stamen tube purple, glabrous or subglabrous, 7-8 mm long, with longitudinal veinlets, tube orifice with 10 subulate, 2-3 dentate lobed lobes, anthers 10, inserted on the inside of lobes, alternate with lobes, oblong, apex slightly convex; Ovary subglobose, 5-6 locules, glabrous, ovules 2 per locules, style elongated, stigma capitate, apex 5-dentate, not extending staminal tube. Drupe globose to elliptic, 1-2 cm long, 8-15 mm wide, endocarp woody, 4-5 locules, 1 seed per loci; Seed ellipse. Flowering from April to May, fruiting from October to December.
Ecological environment: It grows quickly on the moist fertile soil, the soil requirements are not strict, in acid soil, neutral soil and limestone areas can grow, is a good afforestation tree species in the plain and low altitude hilly areas, in the village side roadside planting is more suitable. It is more common in the village edge, open land, forest edge, forest, roadside, hills, scattered living, valley, hillside, hillside roadside, sparse forest, sunny slope, miscellaneous wood forest, house edge.
It grows in the wilderness or roadside, often planted in front of the house behind the house. Distributed north to Hebei, south to Guangxi, Yunnan, west to Sichuan and other areas of China. It also distributed in other areas of East Asia, Malay peninsula, Tropical Asia, Subtropical Asia.
Trait identification: The dry cortex is irregularly lumpy, grooved or semi-reeled, varying in length and width, and 3-7 mm thick. The outer surface is rough, grayish-brown or taupe, with interlaced longitudinal wrinkles and punctate grayish-brown lenticels. Remove coarse skin pale yellow; The inner surface is white or light yellow. Qualitative tough, not easy to be broken off, sectional fiber sex, show layer sheet, easy to peel into thin slice, layer upon layer of yellow and white alternate with each other, each layer of thin slice all visible, extremely fine reticulate grain. No smell, bitter taste. Root bark irregularly flaky or curly, 1-5 mm thick. Exterior surface gray-brown or brownish purple, slightly shiny, rough, many cracks. The dry bark which is thin, most lenticels of young bark is visible is better. The root cortex which is thick, embolus removed is better.
