(4) the material medica south yunnan: "stop vomiting blood, nosebleed, blood flow, the urine, blood check woman ren."

(5) "of materia medica" : "all anti-nausea non-traumatic blood, typhoid Hui inverse, lung heat out of nasty, edema, jaundice, hangover cure poison."

6. "the classics on the original" : "cure stomach on gas, five pour hot and smallpox dry purple doesn't pain."

7 "animal and plant folk medicine" : "treat athlete's foot."

Fold the diuretic effect

Cogongrass rhizome decoction and infusion irrigation water, on normal rabbit has diuretic effect, 5 to 10 days, diuresis effect is most obvious, 20 days or so is not obvious. But the doses used especially animals into water are not clear, and the control group, still needs further research. Others think cogongrass rhizome diuretic and contain rich potassium.

Hemostatic effect

Cogongrass rhizome powder can obviously shorten the rabbit plasma calcium compound. But cogongrass rhizome calcium is more, may interfere with the experimental results. Cogongrass rhizome powder on dog or rabbit femoral artery hemorrhage, oppression 1 to 2 minutes, hemostatic effect. Clinical use cogongrass rhizome in the treatment of epistaxis.

The treatment of acute nephritis

Have good effect, can shorten the duration of symptoms. According to dozens of cases of observation, usually in 1 ~ 5 days after the medication urine is significantly increased, up to 1500 ~ 3000 ml daily. Edema is gradually disappear, high blood pressure and urine change is gradually improving and is normal. Average, according to some cases of edema disappeared time about 4 ~ 5 days or one week; Blood pressure returned to normal time in 5 ~ 20 days, an average of 7 ~ 9 days; Changes in the average disappearing time urine test, ranging from 11 days to 26.4 days. For chronic nephritis is diuresis detumescence and certain antihypertensive effect. But for the liver disease caused by edema, ascites and hf, no diuresis detumescence action or effect was not significant. So there's been speculation that the effect of rhizoma imperatae lies mainly in alleviate glomerular vasospasm, thus increase the renal blood flow and filtration rate and diuretic effects; At the same time improve renal ischemia, reduce renin, blood pressure returned to normal. Good curative effect on acute nephritis, chronic nephritis curative effect is poorer, and edema of liver disease and heart disease a few didn't work. Drugs in addition to the individual to a slight dizziness or nausea, no adverse reactions. Usage: general with cogongrass rhizome (one) half a catty, washed chopped, water frying, points 2 ~ 3 times a day. Take 1 ~ 2 weeks or to heal. Also have to cooperate thistle, field thistle, radix rehmanniae, or of mahuang compound treatment. Medication at the same time, must pay attention to stay in bed, water, salt restriction, warm. Add other drugs, when necessary, can be appropriately control complications and infection lesions, etc.

The treatment of acute infectious hepatitis

With 2 two cogongrass rhizome (one), water frying, points take twice a day. Treatment of 28 cases, the results of clinical cure (45 days main symptoms and signs disappeared, liver function returned to normal) 21 cases, improved (clinical symptoms improved, within 45 days of various liver function values fell by more than half, or 45 days completely back to normal) in 7 cases. After treatment, the most main symptoms disappeared in 10 days, hepatosplenomegaly disappeared in 20 days or so; Cereal third transaminase after 45 days, 80% of patients have fallen to normal, jaundice index average 20.15 TianQuan turn to normal. No side effects.

Antibacterial activity

Cogongrass rhizome decoction in vitro for's blessing and song negroponte dysentery bacillus had obvious inhibitory effect, but for tzu chi hayes and snug dysentery bacillus has no effect.

Effects on myocardial 86 rb intake

Cogongrass rhizome comprehensive water alcohol extract 胙 cavity injection can make the mice myocardial increasing intake of 86 rb.

Drug toxicology,

Rabbit irrigation suits decoction 25 g/kg, 36 hours after the activity is suppressed, bradykinesia, breathing faster, but soon recovered. Intravenous 10 to 15 g/kg, is added fast breathing, movement is suppressed. Gradually recovered after 1 hour, dosage increased to 25 g/kg, 6 hours after death.

Other role

Cogongrass rhizome of job 's-tears element has inhibition effect to skeletal muscle contraction and metabolism. In addition to calm, antipyretic analgesic, fever polydipsia, stomach sickness inverse, lung heat asthmatic cough, edema, jaundice, etc.

Nutritional value

Medica map

Mr Kayanne, today is everywhere. Chunsheng bud, such as needle, secular of MAO needle, can be with her, very good children. Xia Sheng white flowers, has yet to fall and withered, its root to white, also very sweet, mining root in June.

Of materia medica

For MAO MAO the dialects, summer flowers, autumn flowers for kan, two similar function, and name may differ, "poem" cloud, hua jian xi, imperata cylindrica beam is also. "Don't record regardless of MAO, kan is two kinds," Mr Kayanne an jian, a bar, and famous unused, and the reinforcement, a kan root. Cover root shape of objects such as steel, can be TongMing reinforcement, and kan also. MAO imperata cylindrica, kan MAO, heteropogon contortus, citronella, BaMao several, leaves are similar. Imperata cylindrica short, April 3, white ear, "fine, its root is very long, white soft such as reinforcement, and nodal, taste sweet, common silk MAO," the classics "Mr Kayanne is also used. The root of the dry, night vision there is light. Kan MAO gave birth to the mountains, like imperata cylindrica and long, autumn flowering stems into guangzhou, such as the national flower, solid black, long, sticky clothes people, its root short hard such as fine bamboo root, section and micro gump, can be used as a medicine, work not as good as imperata cylindrica, "erya" so-called white fu Yang city hua ye jian is also. Heteropogon contortus like kan MAO, and open leaf stems, stems with white powder, root head has a yellow hair, no section, root is short and thin stiff deep autumn flowering spike like kan, is available for 绹, huang kan, the ancient name "don't record" kan root is also used. A 璚 citronella a MAO, MAO, born in hunan province and jianghuai, leaf three ridge, its fragrance, can package through, shrinkage and alcohol. BaMao, leaf such as pu, six or seven feet long, there are two kinds, namely fern also.

Cogongrass rhizome, except v heat, urinate, so it can stop the blood, Hui inverse, asthma, diabetes, cure jaundice edema, but good things also. The world suddenly due to micro, but the matter out agent, injuries and qi, wu enough to know the true? All anti-nausea non-traumatic blood, typhoid Hui inverse, lung breath the nasty, edema, jaundice, drug therapy.
