I posted this in another forum, so I'd thought I'd post
it here too for informative purposes.
Oleuropein and hydroxytyrosol, olive leaf's polyphenols,
apparently block gp41.

HIV docks, or binds, with the CD4 receptors on the surface of
our T-helper cells and macrophages vide gp120, the flower-like
structure on its surface. After attaching to CD4, gp120 detaches
to allow gp41, the "stalk" embedded in its lipid membrane, to
fuse with or lock onto CD4. Once fused, the virus's capsid is
free to enter the cell and replicate itself.

In effect, olive leaf extract acts as a fusion inhibitor. The only
drugs currently being used as fusion inhibitors are enfuvirtide
(Fuzeon) and maraviroc (Selzentry). Enfuvirtide also acts by
interfering with gp41.

Olive leaf extract also has other significant mechanisms of
antiviral action against HIV:

The docking receptor, gp120, is itself blocked by the EGCG.
EGCG has an affinity for CD4, thus competing and interfering
with gp120.
EGCG also has other direct activities against HIV by inhibiting
protease and reverse transcriptase, the replication enzymes
targeted by standard anti-HIV drugs, and destruction of viral
particles.

EGCG also inhibits HIV-associated dementia :
