Common cold and flu are the two most common and contagious viral infections of the respiratory tract. Since the symptoms are alike, often one is confused for the other. The flu symptoms develop quickly and are usually more severe.
The homoeopathic treatment is symptomatic; therefore there is not much difference in the homoeopathic remedies prescribed for cold or flu.
The child with the sore throat generally gets treated with antibiotics. Although the antibiotics may be effective in getting rid of the bacteria temporarily, they do not change the factors that led to the infection in the first place. When the farmer sprays with insecticide or the physician prescribes antibiotics but doesn't change the conditions which created the problem, the mosquitoes and the bacteria are able to return to those environments that are favorable for their growth.
To make matters worse, the antibiotics kill the beneficial bacteria along with the harmful bacteria. Since the beneficial bacteria play an important role in digestion, the individual's ability to assimilate necessary nutrients to his body is temporarily limited, ultimately making him more prone to reinfection or other illness in the meantime.
