Commentary states: Shaohao re (Tidal Fever in Cold Damage) refers to fever that occurs at regular intervals, like the tide. This is caused by pathogenic factors entering the interior. Therefore, symptoms may present as tidal fever occurring during the You hour (17:00-19:00), followed by slight diarrhea; or slight tidal fever with loose stools; or tidal fever accompanied by cough and counterflow qi; or Jie Xiong (Chest Binding) combined with tidal fever. Generally, all cases of tidal fever are due to the internal excess of pathogenic factors. When formulating prescriptions, one should assess the severity of the condition.
