My father is suffering from COPD (chronic bronchitis and chronic emphysema), he is 57 years old and weighs around 40 kg.He was told about it 6 years back in 2004 untill when he was a chain smoker and left it then only.His fev1 count is only 17%.
He used 35% food grade HP orally according to the given schedule but as soon as he reached 18 drops he felt some extreme symptoms like nausea, headache along with extreme weakness. His heart beat went high up-to 130 bpm and thus he just slacked off on it. He can barely walk and even find it difficult to eat food. I just wanted to ask what is the solution to such extreme symptoms because we don't want to quit so easily as there are not much options left after HP.
Another query i had in my mind was that can anyone tell me that among either oral and inhalation method which one shows better and quick results?
