apple cider vinegar
Apple cider vinegar has been used for centuries both in cooking, and as a tonic to supposedly help in many things like weight loss, diabetes, and heart health. Although, none of this has been proven, one thing remains certain, and that is raw apple cider vinegar contains multiple enzymes, and helpful bacteria that strengthen your immune system.
Make sure you buy the raw, unfiltered kind for maximum health benefits. Whatever you do, don't drink it straight! Mix 1 Tbsp. of vinegar with twice the amount of water, and 1 Tbsp. honey. Honey is a natural anti bacterial.
