We’ll soon be in winter when the immune system is often at its weakest. If you get a cold, do remember that standard medications may not be the most appropriate when a natural immune booster may be a better choice. Many medicinal plants also block infections, strengthen the immune system and alleviate inflammation. For example, ginger and thyme have an expectorant effect, eucalyptus oil relieves coughing and echinacea and sea buckthorn strengthen the immune system. At the onset of a cold it certainly makes sense to start with natural remedies. However, if you don’t feel better after a few days, you should see your health care provider.
