According to Dr. Axe's article, there are 20 unique uses for apple cider vinegar:
Acid Reflux Cure
Weight Loss Aid
Cure a Cold
Ease Varicose Veins
Heal Poison Ivy
Blood Sugar Balance
Considering all the great things Apple Cider Vinegar can do, $9.99 for 946 ml at Country Grocer is very reasonable. I can personally attest that it has totally relieved my acid reflux. Just add a teaspoon of ACV to a glass of water and drink before your meals. Fantastic. I prefer Bragg because they use glass bottles rather than plastic.
