There are many things that l have tried.
Astragalus
Olive leaf extract
Oregano oil
Clove oil
Echinacea
Garlic
These can be ingested, with direction.
Also effective for me, was massage, when l was quite sick, and coughing badly.
The masseuse thumped on my back, whilst l was coughing, which actually loosened the large fungal ball, and l coughed it up, the next day, and could breathe again
