    Dear Reader,

    This is news message from http://www.herbsmd.com - a new website regarding natural & Alternative
    health care tips and products.

    Now you will read our first article regarding Allergies from http://healthgate.com/.

    About 7% of all Americans suffer from hay fever, an allergic condition that can cause runny nose,
    sneezing, and teary eyes. It is known officially as allergic rhinitis, allergic sinusitis, or
    allergic conjunctivitis, depending on whether symptoms manifest mainly in the nose, sinuses, or
    eyes, respectively. Hay fever usually peaks when particular plants are pollinating or when molds are
    flourishing. People who suffer from year-round hay fever may be allergic to ever-present allergens
    such as dust mites.

    Here's how hay fever works. In response to the triggers noted above, an individual prone to
    allergies develops an exaggerated immune response. Substances known as IgEs flood the nasal
    passages, white blood cells called eosinophils arrive by the millions and billions, and inflammatory
    substances such as histamine, prostaglandins, and leukotrienes are released in massive amounts. The
    overall effect is the familiar one of swelling, dripping, itching, and aching.

    The mechanism of allergic response is fairly well understood. Why allergic people react so
    excessively to innocent bits of pollen, however, remains a complete mystery.
