The Natural Medicines Comprehensive Database states that preventing the common cold in the first place is the best defense against the illness. Though several studies have been conducted to determine the effectiveness of touted "natural cures" and herbal remedies, mixed results threaten the reliability of positive outcomes. Experts believe that using immunodulators, or herbs, vitamins and minerals which have been shown to increase the response of the immune system, may help to prevent the common cold or reduce its length and severity of symptoms. Following are some of the most common immunodulators used to prevent and potentially treat the common cold.
Echinacea
Echinacea is an herb used to stimulate the immune system and fight off infection and viruses, such as the common cold. This herb is available in whole form, as an extract or even pills and teas that may be taken at the first sign of a cold to reduce the duration and severity of the illness. However, there is some argument as to the effectiveness of this treatment among medical professionals.
Garlic
Garlic is purported for its antiviral and immunostimulant properties, but more studies are necessary to determine its worth in preventing and curing the common cold. NaturalDatabase.com also states that garlic poses significant risk of interacting with several types of drugs, so check with your doctor or pharmacist before taking this type of supplement.
Ginseng
It is common practice in Eastern Europe to regularly take ginseng in an attempt to prevent the common cold and flus. In fact, a study conducted in Italy actually found that taking ginseng for an extended period of time increased the effectiveness of the influenza vaccine and subjects did not catch the common cold.
Vitamin C
Vitamin C has been studied for years with variable results regarding its effects on the common cold. Some studies have shown that higher doses of Vitamin C can reduce the duration of the cold, but does not necessarily prevent it.
Zinc
Zinc is also commonly used in over-the-counter cold remedies, and is available in nasal spray form or as a lozenge. Various studies have found that taking the mineral within 48 hours of the start of a cold reportedly reduces the severity and duration of symptoms experienced by patients.
Andrographis
Andrographis is essentially the Indian and Asian version of Echinacea, and clinical trials have shown that it can reduce the severity and length of common cold symptoms.
