But that has nothing to do with HIV, neither do garlic and beetroot have anything to do with nitric oxide.

Whether nitric oxide has much to do with health is anothre question. I believe one of the reasons viagra works is due to nitric oxide, so perhaps it's we should be viagring instead.
And we're taking purified alicin at nearly toxic doses. In vitro. Yes, garlic can kill. And it was described to be active in vascular tissue not lungs.
Now Viagra is an interesting bet, but it also does not reach lungs or non-vascular cells.
No mate, post a precise link. This one goes nowhere and I still don't believe you.
