Apple Cider Vinegar is a constant in our kitchen. I add it to all of my bone broths and use it as a general wellness staple for a variety of ailments including sore throat, fatigue and candida. This season seems to be especially intense for my allergies but I am happy to have ACV on hand, as allergy relief is one of the many benefits of this magical fermented liquid.
I am not super used to to taste of ACV so I usually will add a teaspoon in a glass of water and take a couple of times a day. You can also take a small shot if you aren't bothered by the strong flavor but be careful as it is very acidic. Similar to how most treat their cars, I wait until a warning light goes off before I take any action with my allergies. I definitely notice a difference when I am consistent and my sinuses opening up after a day.
If ingesting ACV is completely out of the question because of the taste, you can also inhale the vapors to try and clear your nasal passages and calm allergic reactions.
If you don't have apple cider vinegar in your kitchen, you might be spending more money on over the counter medicine that only masks the problems. I recommend grabbing this one, which is unfiltered and contains the mother.
