Urinary tract infection is a non-specific inflammation caused by the invasion of pathogenic bacteria into the urinary tract, caused by a variety of microorganisms growing and multiplying in the body and invading the mucosa or tissue of the urinary tract. Qinglin Granules is a kind of Chinese patent medicine, which has the function of clearing heat and fire, antibacterial and anti-inflammatory, and thus has some auxiliary effect on the treatment of urinary tract infection. Qinglin Granules is composed of Qu Mai, Bian Cun, Guan Mu Tong, Che Qian Zi, Slippery Stone, Gardenia, Rhubarb and other Chinese herbs, which can act on pathogenic bacteria such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Chlamydia and Mycoplasma, with the effects of clearing heat and fire, promoting laxative and diuretic, antibacterial and anti-inflammatory. Thus, patients can use this medicine to treat urinary tract infections under the guidance of a professional doctor. Patients should note that it is contraindicated for pregnant women because the formula contains bitter cold and laxative ingredients that hinder fetal energy. In addition, weak and elderly people need to use it selectively with their own conditions. In addition, if the symptoms of urinary tract infection are more serious, or if the treatment with the above-mentioned proprietary Chinese medicine is ineffective, the combination of antibiotics can be used as prescribed by the doctor. In daily life, patients should drink more water to increase the volume of urine to flush the bladder and urethra to promote the discharge of bacteria and inflammatory secretions. At the same time, eat a light diet and more fresh fruits and vegetables to reduce urinary tract irritation. They should also correct the habit of holding urine and keep the perineum clean to avoid recurrence of symptoms.
