Limonitum(Limonite).
Pin Yin Name: Yǔ Yú Liánɡ.
English Name: Limonite.
Latin Name: Limonitum.
Property and flavor: warm or neutral in nature, pungent, sweet.
Brief introduction: The Herb Limonitum is brownish iron ore, mainly composed of basic iron oxide [FeO(OH)], it is used as an astringent for the treatment of chronic diarrhea or dysentery, menorrhagia, and leukorrhagia. The herb is commonly known as Limonite, Yǔ Yú Liánɡ.
Source: Herbal classic book defined the herb Limonitum (Limonite) as brownish iron ore which mainly composed of basic iron oxide[FeO(OH)]. This commonly used mineral is introduced:
(1).Brownish iron ore.
Mineral description: Brownish iron ore is also known as Limonite, its main composition is Goethite[FeO(OH)]. The crystal structure is a trimetric system (rhombic system), inside is a chain structure; that contains an indefinite quantity of mineral absorbed water, which is known as hydrogoethite [FeO(OH)·nH2O], and also contains Lepidocrocite [FeO(OH)], hydrogoethite, turgite (hydrohematite, Fe2O3·nH2O), hydrated silica, clay minerals, and so on mixtures; its chemical composition varies according to the production area, the different lumps are also not uniform. Its shape is irregular yptocrystalline blocks, secretion, or concretion; the naked eye can not see fullonite crystals, or in the testa layer there is a fibrous microcrystal. The pure part is yellow, brown yellow, and tawny (yellowish-brown) to brown (different due to gelatinous matter containing water). Stripe marks are faint yellow to tawny. The hydrous brownish iron ore part is brownish-red and reddish; the manganese-rich earthiness part or part with impurities of manganese, cobalt (Co) is brown-black, brown purple; and the part rich in silica, clay, or shell layer is ash gray (grayish white), sallow (grayish yellow). The surface is mostly uneven or covered with powdery brown iron ore, and has a submetallic lustre or earthy luster. nontransparent and has no cleavage. The broken fracture is not flat or has structures of testa layers, and lamina layers, showing different colors and fracture surface states. Its hardness value is 2–5, or 1-4. The hardness of the dense part is near that of the knife, and the hardness of the loose part is lower than a finger nail, but it can grind lines and patterns on fingernails and coins. Its relative density is 3.3–4.3. The herb of a better grade has no smell, is tasteless, and has no sandy sensations when chewed.
Ecological environment: Brownish iron ore is mainly composed by the iron ore containing oxidation decomposition, and then by hydrolysis collection and deposition. It is mainly formed in the weathering crust on the earth's surface. The main production areas are the middle reaches of the Yellow River, and the lower reaches of the Yangtze River.
Characters of herbs: The herb is a lumpy aggregate with an irregular rhombic blocky or ovoid nodule shape that has a core or hollow, but it is rare to see it intact. Usually, the shell is separated from the core, and the shell is broken into irregular rhombus blocks or flat blocks with different sizes and thicknesses. The surface is mostly uneven (sags and crests), khaki, tawny, and brown; the inner surface is coarse and rough, attached with khaki fine powder; the herb is heavy, and its texture is firm, but it can be smashed, the fracture surface is lamellar (lamellate), in different colors, such as khaki, brown, puce (purple-brown), gray-cyan (gray-blue); the thickness of each layer varies, and generally, the brown layer or puce layer is the thickest. The concretion is subsphaeroidal (nearly spherical), with a coarse and rough surface and attached fine powders, yellow-brown to brown, the fracture surface is not lamellar (not in layers), but there are many faviform (honeycomb-shaped) small holes; Some of them have no core when they are broken, have yellow powder, dirty fingers when touched by hands, and slightly slippery sensations (lubricous). The herb has a smell of soil or a slight odor, it tastes mild, and there is no sense of sand when chewing.
Medicinal efficacy: Astringent and relieving diarrhea, astringgent and hemostasis, stop leukorrhea. It is indicated for chronic diarrhea and protracted dysentery, hemafecia (hematochezia, passing blood in stool), metrorrhagia and metrostaxis, morbid leukorrhea, anal fistula, etc.
