I have been using this mixture for my kids and it seem to be working magic. The result is not instant but you would notice a difference.
550 ml hot water
4 tablespoons runny honey
strawberry and cucumber to flavour
Juice lemon and lime using a juicer or squeezer.
Grate the ginger using a grater. Place in a bowl.
Add half of the boiled water into the grated ginger, then sieve into a jug, using a sieving bag.
Add honey, shake well until well mixed.
Add juiced lemon and lime mix. Using a spoon, mix well and then add the remaining hot water.
Allow to cool down and slice in the strawberry and cucumber for flavour.
Store in an air tight bottle and place in the fridge.
