Antiallergic medicines are used to treat allergies and reduce symptoms such as sneezing, itching, and swelling. These medicines work by blocking the action of histamine, a substance released by the body during an allergic reaction. They are usually taken in the form of tablets, capsules, syrups, and injections. In some cases, antiallergic medicines can be used in combination with other treatments, such as steroid creams, to provide relief from allergies. Antiallergic medicines are generally safe and effective, but some may cause side effects, such as drowsiness, dry mouth, and dizziness.
Joshanda, a polyherbal Unani (Greco-arab) formulation comprising seven herbs is extensively used in the treatment of upper and lower respiratory catarrh. The word “Joshanda” is derived from two words i.e. "Joshanidan” which means boiling and “Andah” which means “prepared by” thus Joshanda meaning, “prepared by boiling” (Vohora, 1986). Decoction of Joshanda mixture is prepared extemporaneously by boiling it for a substantial length of time.
