Contraindications to drinking dried ginger in boiled water are that it is contraindicated in cases of blood heat and yin deficiency.
Dry ginger is the dried rhizome of ginger. The flavor of dry ginger is very pungent, very hot, and very dry, so it is not recommended for those who have blood-heat paranoia (the heat evil causes the blood to go out abnormally), vomiting blood, epistaxis and so on, and it is also not recommended for those who have a deficiency of yin and internal heat.
In addition, the dosage of dry ginger should be strictly controlled, and the specific dosage needs to be judged by a physician. Generally speaking, dry ginger can be used for the treatment of yang syndrome, cold drinking and coughing, cold spleen and stomach and other diseases.
The effect of a single Chinese medicine boiled in water is relatively limited, and cannot replace a variety of medicines to play a better therapeutic role. It is recommended to use under the guidance of a professional physician, not self-medication, in order to avoid damage to their own organism.
