Foot soaking in farzhi has limited effect on tranquilizing the mind and expectorating phlegm, and is generally not recommended for foot soaking. As a traditional Chinese medicine, Yuan Zhi is recommended to be decocted with water to tranquilize the mind and promote intellectual development, or used externally to dissipate carbuncles and swellings in appropriate amounts. It is bitter, pungent and warm in nature, and belongs to the heart, kidney and lung meridians. It is effective in calming the mind and promoting intelligence, harmonizing the heart and kidneys (the fire in the heart descends and the water in the kidneys rises, which are in mutual control), expelling phlegm, and dispersing carbuncles and swellings. It can be used in the treatment of insomnia and excessive sleep, forgetfulness and palpitations caused by the lack of harmonization between heart and kidneys, trance, coughing and vomiting, ulcers and swollen poisons, and distension and pain in the breasts. The adverse effects of Yuan Zhi are not clear, and it should be used with caution for those with solid heat or phlegm fire. Foot bath is not conducive to the efficacy of Yuan Zhi, if you need treatment, please consult a doctor in time, under the guidance of the doctor to use the correct medication.
