Alternative medicines or supplements
Many people use
alternative medicines or supplements to prevent colds or to shorten their cold
symptoms. Before using any treatment for your cold symptoms, it is important to
consider the risks and benefits of the treatment. For more information, see the
Complementary Medicine. Some of the common alternative
medicines or supplements used are:
- Echinacea. Study results differ about whether echinacea can keep you from getting a cold or can help you get better faster. Echinacea can cause severe
allergic reactions in some people with a history of
asthma, allergies, hay fever, or eczema.
- Vitamin C. Long-term daily use of vitamin C
in large doses does not appear to keep you from getting a cold or help you get better
faster. There may be a slight
reduction in the length of time cold symptoms last when high doses are taken.
Additional studies must be done to determine how much vitamin C is needed to
reduce the length of time cold symptoms are present.
- Zinc. Using a product containing zinc may help shorten the length of your cold by up to a day.1 But you have to take the zinc as soon as you have any cold symptoms. In some cases, zinc products that you spray or place into your nose can cause permanent loss of the sense of smell.2
