ACV is the one health panacea!
Use it for cooking, cleaning (clothes, house, food, body inside and out), etc. There have been volumes of books written on this one product.
One word of advice on using ACV. It works best as a health aid if the 'mother' is 'alive'.
You can tell if the mother is alive by floating strands of proteins in the ACV.
Even the best quality ACV (Bragg's) has been sitting for months. This isn't such a bad thing, unless you want a living culture. The process of culturing starts with raw apple juice then yeasts and lactic cultures convert the sugars to alcohol, once all the sugar is converted to alcohol the yeasts and lactic cultures die off from lack of food and the strong alcohol environment. Then a special culture begins to feed on the alcohol, taking many months to sometimes years to fully be converted to the healthy form of ACV as we know it.
So what I'm getting at is that the long shelf time has allowed the 'mother' to use up all her food (the alcohol) and begin to die off. This is evident by no strands of proteins floating and only a thick layer of sediment on the bottom of the jar (like unfiltered beer). This layer is the dead or dieing culture. Again there is nothing wrong with buying and using this ACV, it has all the healthy acids intact. But living is always better for ingesting. To revive the ailing culture, I recommend 2 tablespoons of a good quality mead (pure honey wine) to your 32oz bottle of ACV, then put in a warm place for about a week. If there is any viable culture left, this will revive the 'mother', and produce lots of 'baby mothers' and a even healthier ACV. If after a week or two,you don't notice any strands in the ACV this means all viable culture has died and gone to Bacteria Heaven. A moment of silence please......
No worries, don't consume your failed ACV (contains alcohol, use for cleaning), just go to a different store to find the most recent shipment of ACV (most likely still active), repeat the above culturing process till you have a viable culture then add your living ACV to the failed batches and viola! you have a family of living 'mothers'! To continue this 'living legacy', just add some Mead and some living ACV to your next bottle.
One more note, it is best to buy your ACV in glass jars not the plastic jugs. Would anyone like to explain why?
