Seconded.
I... I don't know how to get it across; For the love of God read the literature on NAC, alpha lipoic acid, bromhexine, and ambroxol.
Just... read. Read the molecular biology papers.
"just read the paper" is a bogus argument.
There are thousands of subjects with thousands of papers. To read them all would take thousands of years.
The reason we use summaries is because there is no time to be an expert at everything.

Where would you recommend?
Would regular engineers like us understand molecular biology papers?
