Drinking ginger tea during winter is considered beneficial for health. If there is no ginger in the morning tea, then it is not enjoyable. Ginger is considered very beneficial for health, but ginger tea can prove to be harmful instead of beneficial for health. Excessive consumption of ginger tea can cause stomach-related problems. Apart from this, tea with too much ginger can also lower your blood pressure. Drinking one cup a day is fine but not more than that. If you are also fond of drinking ginger tea, then know what are the disadvantages of it.
