Many cold symptoms are due to the body’s immune system reacting to the virus. The goal of naturopathic treatment is to work with the body’s defense mechanisms by enhancing immune function rather than suppress symptoms with nasal decongestants and analgesics. For this reason, cold symptoms may temporarily worsen when treating with natural therapies. However, the duration of the cold is usually shorter. It is not necessary to use every suggestion to treat a cold; any combination will help.

Nutrition Remedies

A healthy immune system is the best prevention against colds and nutrition is the key to a healthy immune system. Once a cold has taken hold, the following can be helpful in boosting the immune system:Eat lightly. Let your body’s energy go toward eliminating the virus instead of digesting food.

Drink plenty of water, herbal tea, diluted vegetable juice, and soup. Do not drink fruit juices, dairy, coffee, alcohol, or soda.

Limit sugar intake. Sugar intake depresses the immune system.

Herbal Medicine Remedies

Herbal medicines rarely have significant side effects when used appropriately and at suggested doses. Occasionally, an herb at the prescribed dose causes stomach upset or headache. This may reflect the purity of the preparation or added ingredients, such as synthetic binders or fillers. For this reason, it is recommended that only high-quality products be used. As with all medications, more is not better and overdosing can lead to serious illness and death.
