The main functions of Shenjing tea are nourishing kidney essence, strengthening kidney diuresis and producing sperm. It is mainly used for treating soreness of waist and knees, osteoporosis, impotence and premature ejaculation caused by kidney-yang deficiency, and can also increase the survival rate of male sperm. In addition, Shenjing tea also has the functions of clearing away heat, relieving insomnia, dreaminess, irritability and other symptoms.

However, kidney essence tea also has some taboos. First of all, patients with cold essence tea and weak gastrointestinal function are prone to abdominal pain and diarrhea after drinking it. People who are allergic to it will have erythema and rash all over their bodies. Secondly, kidney essence tea is generally forbidden for children and pregnant women to drink, because it generally contains caffeine, which may lead to increased heart rate of children and pregnant women and affect their appetite. In severe cases, it will lead to insomnia and malnutrition, and increase the burden on the heart and kidneys.

Therefore, taking kidney essence tea must strictly follow the doctor's advice to avoid uncomfortable symptoms. During tea drinking, the diet should be light, eat more foods with high dietary fiber and vitamins, such as celery, wax gourd and apples, and make a reasonable exercise plan to enhance immunity. If you feel unwell during drinking, you need to seek medical advice in time.
