Echinacea

• This herb has achieved almost celebrity status when it comes to fighting infections. Also known as purple cornflower, echinacea can boost the immune system when you have a cold. It increases the production of white blood cells that go after the cold virus. It also stimulates the killer cells that fight virus-infected cells. Use echinacea early at the first sign of a cold, because it is less effective once the cold is entrenched. Echinacea is available at most health food stores; take in the form of a tincture for a cold, as this is typically the strongest preparation available. Use 1 teaspoon of tincture in 1/2 cup of water. Take five times a day during the initial stages of a cold.
  
  

Goldenseal

• Goldenseal equals echinacea's status as a potent cold and infection fighter. This potent antibiotic herb, which contains alkaloids in the root, can reduce inflammation. It helps to restore the ability of the mucous membranes to immobilize the cold virus. Goldenseal works well with echinacea. Look for a tincture of goldenseal that has an herb to alcohol ratio of 1:5. Take 2 teaspoons of the tincture in 1/2 cup of water three times a day between meals. It tastes terrible, so drink it quickly. Alternatively, take three 500 mg capsules per day to remedy a cold. Avoid taking for longer than a week, as it may become toxic at that level.
  
  

Sage

• Sage is an antiseptic and and astringent; it helps fight infections by drying up mucous membranes, and lessening the amount of postnasal drip associated with colds. You can find dried sage for medicinal use at health food stores. Steep 1 teaspoon of dried medicinal sage in 1/2 cup of boiling water. Strain and drink slowly. Sage is very strong and bitter; you may want to sweeten with honey. Avoid taking for more than a day or two, as sage can be quite drying.
