This is a vascular reaction of the skin characterised by the transient appearance of elevated patches which are redder or paler than the surrounding skin and often attended by itching. In Ayurveda, this is called shita pitta.
Allergens, taking cold bath immediately after exercise, when the body is hot, and mental excitement are the most important factors for the causation of this disease. Intestinal worms and exposure to the cold wind often cause urticaria. These patches appear all over the body suddenly or gradually. There may be severe itching. The patient is usually constipated. He may get attacks of cold, cough, bronchitis and stomach disorders.
Sutashekhar rasa, brihat haridra khanda, triphala churan, haridra khanda,manikya rasa, poornabhra rasa are ayurvedic formulations for urticaria.
