Do you have a treatment for hives. can you get hives from drinking tea? any suggestions for what hives come form?

Antihistamines: Tea would be an unusual trigger for hives. Acute hives come from food or drug allergy, insect bites and sometimes viral infections. Hives that last longer than 6 weeks can be "autoimmune" where body seems to react against itself, physical (cold, heat, pressure, etc) or unknown. Best treatment is antihistamines such as claritin, (loratadine) zyrtec, or Allegra which don't cause much drowsiness.
