Question: I want to try ACV for sinusitis, which usually occurs after a cold. What dose should I start?
Answer: The traditional dosage of ACV is 2-3 TBLS of ACV in 8 oz of water 3x a day. Add honey to taste.
To help relieve the pain of sinusitis, both Patrick Quillin PhD ( in his book Amazing Honey Garlic and Vinegar) and Cynthia Holzapfel ( in her book Apple Cider Vinegar for Weight Loss and Good Health) suggest drinking a glass of water with 1 or 2 teaspoons of ACV added, every hour for 6 to 8 hours.
For sinus headache, Marie Nadine Antol, in her book The Incredible Secrets of Vinegar, recommends adding an eight of a cup of ACV to a cool-air vaporizer and inhaling the infused-air directly for 5 minutes. After that lie down for 20 minutes and wait for your respiratory passages to clear.
