Allergy is an abnormal response of the immune system to specific substances when they enter your body through your nose or mouth. The substances that trigger allergic reactions are known as allergens. As soon as your skin is exposed to an allergen or if you inhale or ingest an allergen, your immune system will rapidly increase the production of immunoglobulin E antibodies.
Although, these antibodies could protect us from parasites they could not get rid of the allergens from the body. Excess immunoglobulin E antibodies will stimulate histamine secretion. Histamine secretion is associated with allergic reactions such as sneezing, coughing, stuffy or runny nose, itching and skin rashes.
Staying away from allergens is the only effective way of preventing allergic reactions. However, if you accidentally inhale or ingest an allergen, antihistamine medications can give you relief from the allergic reactions.
Pollens and dust are common causes of allergies. To treat this condition, you should use a saline nasal spray to clear the sinus and nasal passages. Nasal wash or nasal irrigation is the best method of cleaning the nasal passage. Besides washing the nasal passage and removing the allergens, the saline wash acts as a natural decongestant and thins the mucus clogging the sinus. Moreover, the antibacterial property of saline water could treat any secondary bacterial infection that tends to worsen the allergy attack. Saline water could even be used for gargling, rinsing the mouth and washing the sites of skin allergies.
For allergy relief you can take the help of certain herbs known for their antihistamine properties. Butterbur is a common European herb used for treating allergies. Goldenseal and nettles are also commonly used for treating the symptoms of allergy. To enhance the property of the saline wash, you can add an herbal extract or concoction to the saline water.
Spices are most effective in providing relief from runny or congested nose, a common sign of allergy. Hot spices such as cayenne pepper, garlic, clove, fenugreek, ginger and onion could thin the mucous. The thin mucous will naturally wash away the allergens from the nasal passage.
