Thanks to my midwives for this amazing cure! 
Ingredients
-1 cup dried elderberries
-4 cups filtered water
-4 quarter-inch slices of fresh ginger
-2 cinnamon sticks 3 cloves
-1 cup raw honey
Add all ingredients except for the honey into a medium saucepan. Bring to a boil, and then lower heat to medium. Continue simmering for 30-45 minutes until the liquid is reduced to half. Before the liquid cools, strain through a fine mush strainer. Allow the liquid to cool to about 118 F to preserve the enzymes in the raw honey, and gently combine the arm reduced berry liquid with the raw honey. Store in a jar in the fridge for a few weeks. For longer storage, freeze into ice cube trays to defrost for later use!
First I bought this elderberry syrup for $18 in wholefoods store. Then got this recipe from Midwives of NJ. The whole bag of elderberry ($15) bag yields 6 cups which turns out to be much cheaper.
Here is anti-flu recipe from my midwives:
For all adults (including pregnant women): elderberry syrup 2 teaspoons a day, Vitamin D3: 4000 IU per day, Vitamin C: 1000 mg per day
For children: Elderberry syrup 2 tablespoons a day, Vitamin D3: 2000 IU per day,Vitamin C: 500 mg per day
If the baby is still feeding and mom is taking the syrup, then baby does not have to take the syrup.
