Having the flu is a terrible experience that can leave you feeling like you've been hit by a truck. Boiron's Influenzinum is a homeopathic dilution prepared from the approved seasonal inactivated influenza vaccine. Note that this is not a vaccine and does not confer the benefits of having the vaccine.
If the tickle in your throat won't go away and you can't stop coughing, try Hyland's Bronchial Cough. This homeopathic remedy seeks to provide temporary relief of coughs with mucus due to the common cold.
