Many people know about echinicea but did you know that ginger is also great for reducing cold symptoms? Boil some freshly grated ginger in water and drink 3-4 times a day. This will help with cough and headache and I have even been told it even increases libido.
Vitamin C is also a great alternative to allergy medicine. Vitamin C acts as a natural antihistamine. If you suffer from seasonal allergies try drinking a glass of OJ a day. See what it does for you. Another good addition is a spoon full of honey. This helps with coughs especially those caused by post nasal drip. Be sure and buy local honey though made from honey bees in your area.
