Huoxiang Zhengqi Water is generally used to treat summer colds, dizziness, fever, or diseases accompanied by cold symptoms. It has no special effect on treating athlete's foot. Athlete's foot is caused by fungal infections and is contagious and recurrent. For treating athlete's foot, it is best to use formal medications, otherwise, due to its high contagiousness, it might spread to family members. Currently, commonly used ointments include Naftifine Ketoconazole Cream or Nitrate Sertaconazole Cream, and the treatment usually requires a long course, at least persisting for more than a month. Or after the symptoms have completely disappeared, continue using it for about half a month more, which can generally cure it completely. Towels and basins for washing feet, used daily, must be separated from those of other family members to prevent cross-infection.
