Was suffering from cold and cough and no matter what medicine I took, I just did not get any relief. One of my friends asked me to try alternative medicine .i.e. natural products. I bought a herbal cough and cold medicine from Natures Source and took it for just two days. Frankly I was surprised to see the fast action. I now feel natural herbal products are best for preventing health problems and improving immunity, particularly for fighting cough and cold or allergy or diabetes or even cardiovascular problems. What do you say?
