A 39-year-old man and his wife are brought in by ambulance

to the ED due to disorientation and agitation. They were found by neighbours,

wandering in their street.  The ambulance

team says they seemed to have drunk a herbal tea that morning.

On examination, they are disoriented with tachycardia,

dilated pupils, dry mucous membranes, dry skin and urinary retention.
