  20. Hello! I am suffering from urticaria for about 3-4 years. It generally occurs in summer. And main allergens, I think, are various food articles and also sunlight and heat.
    I went to various doctors and they only prescribe me some medicines which causes some temporary relief. Can you please tell me any natural and permanent method to eradicate this disease.

    • Vitamin C: It gives strength to the body’s immunity system.
      Stinging nettle: It is not very popular that stinging nettle is known to be a way to cure hives. Place an extract of stinging nettle on the area which is affected by hives.
      Apple cider vinegar: To be precise, apple cider vinegar should be combined with cornstarch to make a pasty mixture and then put it on the surface where the skin is influenced by hives. Do it after bathing to make the most of its effectiveness.
      Aloe Vera: The gel from Aloe Vera is the main ingredient to reduce the itchiness. Don’t afraid to place it directly on the skin. A period of about 30 minutes or so is recommended. After that, clean with water and see how magical and soothing it is.

  21. Hey RR play, first of all, vitamin C containing food articles cause more allergy so I think I should totally avoid it and the other three are also some of the remedies which can only suppress the urticaria but I want to eradicate this disease.
