Take a zinc supplement: Take zinc lozenges or syrup within 24 hours of the start of a cold, as this may reduce the duration of the cold. The important thing is to take the zinc within 24 hours.
Rest. You body needs rest to heal.
Soothe a sore throat. I personally like to gargle with sea salt water - 1/2 tea spoon of sea salt dissolved in a large glass of room temperature water.
Note: This is in appropriate for children as they may not be able to gargle properly.
Sip warm liquids. This could be chicken soup, team or warm apple juice. Personally I like a wedge of lemon in hot water with a little chunk of ginger sweetened with manuka honey.
Vitamin C. The scientific jutry is still out on Vitamin C. Personally I dose up with 1000mg of vitamin C throughout my cold. Taking vitamin C before the onset of cold symptoms may shorten the duration of the symptoms. Vitamin C may provide benefit for people at high risk of colds due the the frequency of exposure.
Echineacea. Study results on whether echinacea prevents or shortens colds are mixed. Some studies show no benefit. Others show some reduction in the severity and duration of cold symptoms when taken in the early stages of a cold. Different types of echinacea used in different studies may have contributed to the differing results.Echinacea seems to be most effective if you take it when you notice cold symptoms and continue it for seven to 10 days. It appears to be safe for healthy adults, but it can interact with many drugs. Check with your doctor before taking echinacea or any other supplement.
