Mangxiao

(bielu)

[synonym] penxiao (Ben Cao Tu Jing), mirabilite (medical Qiyuan).

[source] it is refined crystal of mirabilite.

Mirabilite

Monoclinic system. The crystal is short columnar, usually dense granular and membranous. Colorless and transparent, but often with turbid white, light yellow, light blue, light green and other colors. The stripes are white. Glassy luster. The fracture surface is shell like with hardness of 1.5-2. The specific gravity is 1.5. It's brittle. It is formed in inland salt lake with saturated solution of sodium ion and sulfate ion.

[preparation method] natural Glauber's salt is dissolved in hot water, filtered and cooled to precipitate crystal, which is commonly known as Glauber's salt. Then wash and slice the radish, put it in the pot, add water and boil it thoroughly, add sodium nitrite and cook until it is completely dissolved, take out the upper liquid after filtration or clarification, cool it and wait for crystallization. After drying, it is Glauber's salt (100 Jin per Glauber's salt, 10-20 Jin with radish). There are also natural Glauber's salt. After boiling, filtering and cooling, the upper layer of Glauber's salt is taken as Glauber's salt, and the lower layer of Glauber's salt is taken as Glauber's salt.

[herbal medicine] is prismatic or rectangular crystal with irregular ends. Colorless and transparent. It's crispy. Without Qi, it tastes bitter, salty and cool. It is better to be colorless, transparent and massive crystal. Soluble in water, insoluble in alcohol. It is easy to be weathered in the air, and the surface is covered with anhydrous sodium sulfate white powder. Aqueous solution shows various special reactions between sodium salt and sulfate.

In ancient times, the Glauber's salt crystallized in the shape of a GUI horn, which was called "horse tooth Glauber's salt".

[chemical composition] mainly contains sodium sulfate. It is often mixed with other substances such as magnesium sulfate and calcium sulfate. Mangxiao is easy to lose water in the atmosphere, so its surface is often white powder; the sodium sulfate content of this weathering Mangxiao can exceed 44.1%.

(1) purgative effect

Mangxiao is a kind of sodium sulfate containing impurities, while xuanmingfen is pure sodium sulfate. After oral administration, its sulfate ion is not easily absorbed by the intestinal mucosa and remains in the intestine to become a hypertonic solution, which increases the water content in the intestine, causes mechanical stimulation and promotes intestinal peristalsis. Salt also has chemical stimulation effect on intestinal mucosa, but does not damage intestinal mucosa. When the concentrated solution reaches the duodenum, it can cause pylorus spasm, thus delaying the emptying of all drugs from the stomach. At the same time, the water in the tissue can be inhaled into the intestinal tube. Therefore, when taking it, you should drink a large amount of water to dilute it. Diarrhea occurred 4-6 hours after administration, and fluid feces were excreted. If used to treat tissue edema, need less water.

② Other functions

In rabbits with experimental appendicitis and perforated appendix, rhubarb paste, Mangxiao paste, garlic paste and vinegar paste were applied on the abdomen, which had obvious stimulating effect on the reticuloendothelial system of appendix and spleen, enhanced the proliferation and phagocytic capacity, and significantly reduced the appendicitis compared with the control group. After applying garlic Mangxiao paste on the right lower abdomen of normal rabbits, local skin irritation symptoms such as fever, redness and blistering were found, and the movement of small intestine, appendix and pouch colon was enhanced; after local ring sealing with 1% procaine, the movement of intestinal tube was weakened. Therefore, its effect is caused by nerve reflex. Due to the increased peristalsis, abundant blood supply and enhanced phagocytosis of reticuloendothelial system, the disease resistance ability of the organism was mobilized. The external application of 10-25% sodium sulfate solution for infectious trauma can add a piece of lymphangiogenesis and has the effect of detumescence and pain relief. 4.3% sodium sulfate can be used as diuretic to treat anuria and uremia
