In my quest to get rid of the cold hives caused by sand fly bites, I have decided to put myself on an experiment. Recent research showed that ginger is actually a potent antihistamine and aids in the treatment of all types of allergies. 
This lowly root plant contains anti-viral, anti-toxic, and anti-fungal properties, and is effective in the prevention of and treatment against the common cold, something which doctors the world over will tell you has no “cure”.
