Rotten ginger is not recommended for foot soaking. Ginger may produce some toxins when it rots, so if there is broken skin on the feet or the patient has foot odor problems, you can’t use rotten ginger to soak your feet. Because the toxic substances produced when the ginger is rotting will invade into the human body along with the wounds of the feet, thus damaging the human health, so rotten ginger is not recommended to use to soak the feet. Foot soaking can improve the problems of cold feet and cold body through the warming effect of hot water, but foot soaking, by itself, does not play a role in the treatment and prevention of diseases. When using ginger boiled water to soak feet, due to the ginger chorine and other ingredients, it will stimulate the skin of the feet, resulting in the expansion of blood vessels in the skin of the feet, thus helping to improve blood circulation. However, if the body exists uncomfortable disease, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for examination and treatment, so as not to delay the condition.
