Allergies are highly prevalent. It is considered the 6th leading source of chronic diseases in the US. The annual number of Americans suffering from different allergies exceeds 50 million.

Allergens trigger the immune cells in connective tissues, also known as mast cells, to release histamines. These newly released chemicals cause the blood flow to surge toward different parts of the body leading to inflammation. Inflammation gives rise to the myriad of allergic reactions commonly experienced, such as sore eyes, rashes, runny nose, and overall discomfort, which can be relieved by the natural antihistamine.

Antihistamines, in general, inhibit the effects of histamine in the body. Prescription and over the counter antihistamine are efficient and quick, but the adverse effects compel people to look for alternatives like antihistamine natural herbs. Intake of these drugs requires precaution. For instance, taking an antihistamines alcohol mixture is a dangerous combination. Food and drinks generally do not affect the medication, but other drugs and substances can worsen its side effects.
