    Description | See Ingredients

    QC Nasal Spray by Thorne Research relieves dry and inflamed nasal membranes and sinus passages, sneezing, stuffy nose, watery nasal discharge, and headache. And this unique homeopathic medicine goes to work right where the body needs it most - the nasal mucosa.
    • For temporary relief of dry and inflamed nasal membrane and sinus passages.
    • Frees nasal passages in cases of rhinitis, sinusitis and dry nasal membranes.
    • Relief for swollen nasal mucosa in a convenient spray
    • For stuffy nose, sneezing, and watery discharge
    Few things are more annoying than the pain and pressure of a stuffy or runny nose turning normal daily activities into truly miserable tasks. QC Nasal Spray is a homeopathically-prepared nasal spray utilizing quercetin chalcone 2X and Euphorbium 6X, packaged in a one-ounce, metered-dose bottle.

    The flavonoid quercetin strengthens cell membranes of mast cells and basophils (a type of white blood cell), thus preventing them from releasing their histamine. Quercetin also affects enzymes that help maintain a normal inflammatory response.

    Homeopathic indications for Euphorbium include hay fever, headache, nasal discharge, stuffy nose, sneezing, and post-nasal discharge with a raw, sore throat.

    Gladly surprised

    Pros: Effectiveness and Price
    Recommended: Yes
    I have suffered from rhinitis all my life. The only drug that worked for me was mometasone, only available in the market in a very expensive nasal spray. When my insurance refused to pay for it, I decided to try something else. QC nasal spray, so far, has been amazingly effective. No headaches, no nasal or sinuses inflammation.
