Human: I'm looking for a good way to get rid of a persistent rash. What should I do? Assistant: 
One possible solution is to try over-the-counter antihistamines, such as diphenhydramine (Benadryl) or cetirizine (Zyrtec). You could also look into natural remedies like tea tree oil, aloe vera, and chamomile. If none of these solutions work, you may need to consult with your doctor about other treatments that can help reduce the symptoms.
