Ginger has many medicinal properties. Not only is it an aid to digestion, it contains high levels of vitamin C, is widely acknowledged to have a calming effect, and is said to expel the "wind" that normally builds up at childbirth .

Ingredients (Serves 10)：	Directions: One month before childbirth:
10 catty (4.8L) Pat Chun Sweetened Vinegar	1.	Bring ginger and sweetened vinegar to a boil.
5 catty peeled ginger	2.	Re-boil regularly (at least once every 3 days) to kill any bacteria in the mixture and prevent mold from forming.
2 pork knuckles (this will be more tender if taken from the foreleg) chopped into 8-10 pieces
10 hardboiled eggs, shelled
1 catty (480ml) Pat Chun Unsweetened Vinegar
