When you have a cold and cough, you can usually drink saffron water. Saffron water is a traditional Chinese medicine, belonging to the category of Tibetan medicine, which has the effect of activating blood stasis, cooling blood and detoxifying blood, and is used for patients with blood stasis evidence and blood heat evidence, which has certain health effects on patients. However, the coughing symptom of cold is mainly due to the inflammation of the respiratory tract caused by the infection of viruses and bacteria and other pathogens due to the decrease of the immunity of the body. Generally speaking, if you have cough symptoms, you can take appropriate cough and phlegm medication, and give anti-inflammatory treatment for causes other than cold symptoms, antiviral medication for viruses, and antibiotics for bacterial infections. Drinking saffron water can only play a certain role in health care, but not as a treatment.
