Applying cooling oil to the navel is mainly used to treat diarrhea caused by abdominal cold, which involves applying cooling oil evenly to the navel and then covering it with the hand for a period of time to facilitate the rapid absorption of the medicine.

Cooling oil is a common medicine that mainly has the effect of cooling and dissipating heat, and can also have the effects of awakening the mind, invigorating the spirit, and relieving itching and pain. It is mainly used to improve common cold headaches or heatstroke, and can also be used to improve motion sickness and insect bites. It can play an auxiliary role in adjusting diarrhea caused by abdominal cold, but if the symptoms are severe, it is best to go to a local regular hospital for further examination and treatment in conjunction with medication to avoid the exacerbation of diarrhea symptoms. In addition, when using cooling oil as an auxiliary adjustment, it is necessary to observe for any allergic reactions, such as skin redness or itching, and stop using it immediately if any abnormalities occur.

During the recovery period, it is very important to pay attention to dietary adjustments. The diet should mainly consist of liquid or semi-liquid foods, such as millet congee or vegetable congee, soft noodles, etc. This is particularly beneficial for the absorption and digestion of the gastrointestinal tract and will not increase the burden on the gastrointestinal tract. In addition, it is necessary to drink more warm water because diarrhea can deplete a large amount of body fluids, to avoid dehydration or electrolyte imbalance.
