Dandelion as an herb has some anti-inflammatory effect, but it is not effective to rely on this herb alone to treat UTIs. Urethritis is an inflammation of the mucous membrane caused by the invasion of pathogens due to damage to the mucous membrane of the urethra. Usually, you need to use antibiotics for inflammation control, such as the use of azithromycin, cephalosporin or levofloxacin, etc. You can also use Chinese herbal anti-inflammatory drugs for supplementary treatment, such as busulfan anti-inflammatory oral solution. The effect of anti-inflammatory drugs alone is generally not good, and UTIs should be controlled with antibiotics as soon as possible to avoid long-term prolonged UTIs or cause cystitis, or even upper urinary tract infections.
