Tongue cracking can recover by itself, but it depends on the time and degree of the dysfunction of the internal organs. If the dysfunction of the internal organs causes the tongue cracking for too long, too long or the condition is too severe, it is not regulated for a long time, and one does not regulate all aspects of life and diet. Tongue cracking will not recover, and the condition itself will get worse. Generally, cracked tongue indicates deficiency of stomach and yin or deficiency of qi and yin, long-term depletion of essence and blood, if the time is relatively short and the disease is mild, the cracked tongue can be gradually improved through dietary adjustment, through improving sleep, improving living habits and quitting smoking and drinking. If the condition is longer, heavier and more prolonged, the tongue may be aggravated from cracked tongue to mirror tongue, stomach yin depletion and dysfunction of internal organs will lead to further deterioration and cracked tongue will not recover on its own.
