• Grab a bottle of vitamin C. Take 3–5 grams daily for a few days; it usually does the trick.
  • Take pure arabinogalactans (an immune-boosting nutrient from the larch tree) at the very first sign of a cold. Start with 1 1/2 teaspoons and follow label directions for subsequent doses until you feel better.
  • Ginger tea works wonders. Boil organic ginger root in water for 15 minutes to make a strong tea. Dilute and sip throughout the day.
  • Try elderberry tincture and the patented homeopathic remedy Oscillococcinum. Both have been shown to shorten the flu's duration and intensity when taken at the first symptom.
