[Baizhu can spot some signs of dehydration (dry lips, sunken eyes), but there doesn't appear to be any fever. The eyes are not discolored, but may not be entirely focused. There's no evidence of bites, significant cuts or bruising, though he can tell that the patient is breathing faster than usual and overall is somewhat shaky.

As for signs of pain, that's pretty evident when coughing occurs. He will not discover plant residue.]
