Antibiotics are potent drugs used for killing bacterial and fungal infections only. They are often misunderstood for treating varied viral illness like cold, flu, coughs, rashes et al. Taking dosages of anti-bodies for curing cold will only worsen your symptoms and enhance their duration. This is because the wrong consumption of anti-bodies strengthens the resistance of viruses towards these medications.  
Instead of anti-biotic, people suffering from cold should opt for anti-viral drugs. These drugs, as the name suggest, are specially formulated to attack the infestation of the viruses inside the body. In addition, essential elements like Zinc, Vitamin C and Echinacea bear combative powers to fight the viruses. These elements can be taken regularly in form of capsules. Further, there are numerous natural ingredients that aid in vanquishing the virus based infections in the body. Garlic is one such powerful agent that bears strong medicinal properties to detoxify the body. It is recommended to eat several cloves of raw garlic at the hit of the morning in order to evade oneself from several viral infections. Eucalyptus oil is another natural cure for common cold. This is a natural anti-viral agent that soothes respiratory congestion, sore throat, sinusitis and many other illnesses.
