If you are congested from a cold, flu, acute bronchitis, hay fever or other respiratory irritants, you can progress to healing more quickly by improving the productivity of your cough. Yep, that means coughing up as much phlegm as possible. It may not be glamorous, but it may help relieve your discomfort and help you get over your virus or allergy flareup sooner and let you get back to the more charming side of your life. Naturade Herbal Expec is here to help, with an expectorant that can provide soothing relief and may shorten your cold. Each dose includes 150 mg of Guaifenesin, a compound derived from the guaiac tree that has been shown to thin phlegm and bronchial secretions, reducing their viscosity and adhesiveness to remove them from your airway for expulsion.
