Im getting over a cold too, last week I had a sore throat and cough.... as far as I remember I have always gotten some kind of upper respiratory cold bug this time of year regardless of what type of diet.....my kids seem to bring in all sorts of bugs from all over, and there are times when it seems like half the town has some kind of viral detox going on... though my children typically only get mild symptoms of a 24 hour virus... The common cold seems to have as much to do with other environmental conditions like air quality and seasonal changes, as diet.... weather shifts trigger all all types of microbial spore and viral blooms, which work within the population to trigger herd detox reactions.
Its always runs its course in my experience without need for drastic interventions, and afterward I feel rejuvenated...
Some basic recommendations for the common cold I follow are close to djrs
Time to rest is important.... I usually dont do a complete fast for a cold, but I will eat much less, nothing for breakfast and maybee something like an egg or two through the day and small meal for dinner..depending on my instinctive feelings... lots of fluids are recommended, spring water is best... I dont like using lots of so called natural remedies, and have found most herbal cold supplements to be ineffective. I believe that what ever discomfort one experiences is part of the healing process and is important to go through... During this last cold I have used goldenseal tea which seems to have helped, though I think I started drinking it right at the time I began to feel better...coincodence maybe?....still I think it may be supportive in helping me clear out the rest of the mucusyness
