Garlic is great as a preventative and as a treatment. Take two tablets three times a day until the mucus production has slowed down dramatically, or until the color of mucus becomes clear rather than yellow or green. Garlic can also help treat ear infections. Squeeze a garlic clove until the juice runs into a cotton ball and place the cotton ball in the ear. Raw garlic has antifungal, antibacterial, and antiviral properties. Researchers in England found that garlic can speed up recovery from a cold and increase resistance. Study participants had half the number of colds and made a more rapid recovery.
This herb is known to support the immune system and to stimulate the body's ability to fight viruses.

Even Shakespeare mentions it in his play The Merry Wives of Windsor: "What says my Aesculapius? My Galen? My heart of Elder?" Studies have shown elderberry to inhibit replication of human influenza virus type A, type B and animal strains from swine and turkeys in cell cultures and to reduce the duration of the flu by approximately four days.
