The total effective rate of treating male infertility with oral solution of compound five seeds of dihuang was 84%.

The contraindications of cooked dihuang

1. Concoction decoction can not be seen in copper and iron utensils.

"Lei Gong concocted medicinal solution" cloud: ? The raw dihuang, remove the white skin, magnetic pot on the willow wood retort steaming, stalling the gas break, mixed with wine, and then steamed, and out of the dry, do not offend the copper and iron, the people kidney consumption, and white hair, male loss camp, female loss of Wei also. Cooked dihuang concoction is not visible copper and iron, decoction can not be used iron pot, iron pot. The medicinal knowledge: "If you violate the iron, it will make the kidneys disappear. If you violate the iron, it will make the kidneys disappear. Storage should be as the "herb from the new" said:? Taste as sweet as syrup, must be collected in porcelain, in order to its fat soft like moist also.

2. Avoid radish, three white, all blood.

"Materia Medica Pinhui Essentials" records:? Avoid radish, scallion white, leek white, scallion white. The key medicines "medicine" cloud:? Avoid turnip, green onion, garlic, all blood. Covered by the Laptop to lower the gas, three white Xin tunnels away from the gas, affecting the tonic effect of the rhizome. The blood for the flesh and blood sentient products, fear of nourishing too much, so it is appropriate to prohibit.

3. It is not suitable for typhoid families.

The disease of typhoid, the evil from the outside, it is appropriate to evacuate and should not be tonic. As "Shennong Ben Cao Jing hundred kinds of record" said:? And Zhongjing "typhoid fever" one hundred and thirteen square, but the land yellow with the restoration of the pulse. Cover the disease of typhoid fever, the evil from the outside, the most avoided nourishment stagnation. That is, the use of tonic, must be combined with the nature of sparse top, can be into the agent. Otherwise, the evil gas to the inside, there will be harm. Nowadays, people see the evidence, a little bit about the virtual phenomenon, they will be six soup for the common products, kill people like, can win long sigh.

4. Spleen deficiency, phlegm, gas and depression should be taken with caution.

Cooked dihuang taste sweet, sex especially greasy, spleen deficiency, phlegm and qi depression should be used with caution. According to the cooked dihuang sex stagnation, phlegm, qi depression people, can stifle the chest and diaphragm, with appropriate discretion. The Essentials of the Materia Medica: "The ripe one is stagnant. The cooked one is stagnant in nature, if the person with much phlegm and depressed qi can stifle the chest and diaphragm, it should be used with discretion. Tongxuan of the Materia Medica said: "The cooked ground is stagnant in nature. The ripe nature of stagnation, phlegm, fear of mud diaphragm, it is appropriate to ginger fried, in order to control its stagnation. More must be accompanied by sand nuts, incense two flavors, all the gas to the kidneys, but also can dredge the stagnation of the rhubarb, the balance of this medicine.

A comparison of the efficacy of ripened dihuang and raw dihuang on intravascular thrombosis syndromes showed that the Chinese crude ripened dihuang in the form of pig's bile was able to strongly inhibit hepatic hemorrhagic necrotic foci and simple necrosis.

While the antithrombin effect of ripe earth is weaker, application of fibrin plate method to explore the activation of fibrinolytic system through fibrinolytic zymogen activation, found that the ripe earth has an activating effect, while the raw earth does not have this effect.

It has also been reported that there is an hemostatic effect before and after the charcoal stir-frying of Dihuang, and the hemostatic effect of Dihuang after the charcoal-making is not enhanced.

The hemostatic effect of aqueous decoction of raw dihuang, cooked dihuang, raw dihuang charcoal, and cooked dihuang charcoal was analyzed, and the results were not significantly different.

1, the effect of cooked dihuang delay aging

cooked dihuang 20% aqueous decoction daily gavage 0.3 ml *** 45 days, the blood was taken at the execution, and the superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) vitality and the content of lipid peroxidation (LPO) were measured.

The results of ripened dihuang could enhance the GSH-Px activity and reduce the content of LPO in serum, with P<0.05 and P<0.01, respectively, compared with the control group.

2. Effects on hyperthyroidism-type yin-deficiency in rats

The yin-deficiency model of the rat was caused by administering triiodothyronine (T3) to the rats and given 3 ml of a decoction of ripened dihuang (70%) concentration), *** for 6 days, and then the data were measured.

The results of the normal control group compared with the administration group, before and after the administration of drugs, both signs, body weight changes, 24-hour water intake and urine volume, as well as the plasma concentration of the relevant hormones: T3, thyroxine (T4) and aldosterone (AD) were not significantly different (P & gt; 0.05).

However, after modeling, there were very significant changes in the yin-deficient group compared with the normal group, such as excitement and aggressiveness, weight loss, increase in 24-hour water intake and drinking, increase in T3 concentration, and decrease in T4 and AD concentration.

In contrast, the above symptoms and indexes were significantly improved and normalized after the administration of Radix Rehmanniae Praeparata to yin-deficient rats (compared with the yin-deficient group).

For example, plasma AD concentration increased significantly (P<0.05) and 24-hour urine output decreased significantly (P<0.01) in the yin-deficient plus Radix Rehmanniae group compared with the yin-deficient group, suggesting that Radix Rehmanniae has the effect of nourishing the kidney yin and improving the level of AD in vivo.

The T3 and T4 concentrations in plasma of the yin deficiency administration group improved significantly (T3 concentration decreased and T4 concentration increased) and normalized.

It showed that Rudbeckia can not only improve the symptoms of yin deficiency through its systemic regulation, but also regulate the abnormal thyroxine status.
