At the same time, 25 cases were treated with the combination of Legowang and Andrographis paniculata, with similar curative effects. In another case of chronic asthmatic bronchitis combined with left lower pneumonia, 1 tael of Gewang rhizome bark was added to 1000 ml of water and decocted for more than 2 hours to obtain approximately 200 ml; 1 dose per day, divided into 2 doses. The fever was reduced within 24 hours after taking the medicine, and the cough and asthma were significantly reduced. After taking the medicine for 1 week, the inflammation in the lungs was dissipated and absorbed. Another case of acute lung abscess on the right side with an abscess cavity of 4x5 cm. After half a month of treatment with various antibiotics, the fever and purulent sputum remained. So Gewang and Polygonum cuspidatum decoction was used instead. The body temperature dropped to normal on the 4th day, and the abscess cavity disappeared after 20 days. It shrank to 1x1.5 cm and was absorbed and healed after 2 months. In addition to relieving asthma and cough, Le Ge Wang also has heat-clearing and anti-inflammatory effects.

Its therapeutic effect is manifested in the following two aspects: 1. Diuresis: Both acute and chronic nephritis have diuretic effects to varying degrees after taking the medicine. The diuretic effect appears 2 to 3 days after taking the drug and continues to be a diuretic effect. Significant diuresis is more common in the renal degeneration stage of nephritis, and in cases with good physical constitution but partial to damp-heat type, the effect on nephrotic syndrome is poor. Secondary anti-infection: It was clinically observed that patients with Proteus infection who had not been treated with streptomycin were treated with Gewang orally for 3 weeks and had sterile growth in two consecutive mid-section urine cultures; it was also effective against Staphylococcus albus infection.

The patient takes the lithotomy position, undergoes routine disinfection, and slowly introduces the thin end of the sterilized endocervical root into the dilated cervical canal. The silk thread is tied with sterile gauze and stuffed inside the vagina. If the embryo is not discharged within 24 hours, the gauze needs to be replaced to prevent infection. If the baby's root has slipped, it can be re-inserted for the second, third or fourth time until the embryo is discharged naturally.
