I am trained as a scientist (PhD Psych.) and am skeptical and suspicious of the placebo effect, which is real and can be quite powerful.
Three days ago I was about to book in for my third nasal polyp surgery because I couldn't breathe through my nose for the last few months, due to polyps, chronic sinusitis, diagnosed allergies to dustmite and grasses, and severe adult onset asthma.
Oral steroids, steroid sprays, antihistamines, steroid inhalers and ventolin were all still not managing my infections and inflammation. I'm 37 and over the last two years felt like I was pretty much dying.
Two days ago I heard about research showing acetate (acetic acid in vinegar - any kind) treats asthma in rodents. And I learnt that there is a scientific explanation for this effect, which might prove true for humans too. High fibre diets are crucial for gut bacteria, which lead to 'short chain fatty acids', which in turn moderate inflammation. Vinegar is full of these acids and so it is potentially a medicine which can be clinically effective, not just anecdotally through history etc.
So two days ago I started having 2 tablespoons, three times per day. It seems like a miracle, but I have had a clear sinus, with airflow through both nostrils, for two whole days now. It's amazing how dynamic polyps can be. Furthermore, I have clear or very little infected discharge. And before that I was ready for surgery... I didn't even take my steroid spray today - I can't believe it. Asthma is now under control.
I hope that this effect will continue and become a long term treatment for me, and you too if you are reading this. I only give it 4 stars because it is early days. If this continues to work, I will reclaim my life. The only other thing I would ask for is to reclaim my sense of smell, which has been missing for over a decade.
All the best!
