@merpreb I can completely understand and I am not any expert here, but I belong to a land where ayurveda was born. It is believed that oils we use have different properties and used for several and very specific purposes. Interestingly, ghee (pure and organic from cows), has a lot of healing properties and is widely used in India. Ghee made with bilona method is a long process of churning curd (yogurt made in indian way) to extract butter and heating/boiling that butter until water separates (reduction) and leaves behind pure ghee. An ayurvedic medical practitioner will turn a million pages to just explain the benefits of ghee, but I am definitely not in a position and have little to no knowledge on how it is beneficial for shortness of breath. However, I just tried something that I read somewhere in a news article.
