All Sinol and Sinol-M products are zinc-free. No loss of smell (anosmia) has been reported in association with the use of Sinol or Sinol-M nasal sprays. How Sinol Works - Instant Allergy Relief Sinol nasal spray for allergies uses Capsaicin, an ingredient that comes from the pepper plant and is found in most spicy foods. The capsaicin desensitizes the mucous membranes making them less irritated by airborne allergens. Sinol nasal allergy spray will break up nasal congestion fast, cleanse and moisturize the nose, keep your nasal passages moist, clean and bacteria free while it prevents allergy triggers. Sinol over the counter allergy nasal sprays do not dry out the nose like antihistimines and decongestants found in other other allergy nasal sprays. Allergies are a result of an overactive immune system. The allergic immune system misidentifies un-harmful substances as harmful, and then fiercely attacks these substances. These attacks can create problems which may range from mildly inconvenient and uncomfortable, to extremely severe. Some common allergens: dust, mold, pollen, pet dander
