According to Robert Short, an
Australian academic ,Lemon juice has amazing powers to prevent HIV and as
a contraceptive to kill sperm in 30 seconds.
He is Robert Short ,is a fellow in the department of obstetrics and
gynaecology at the Royal Women's Hospital at the University of Melbourne.
His observation:-
The effects of 10 percent lemon juice on HIV in
culture is that it kills the virus very quickly.
Concentration of 20 percent lemon juice in a fresh
human ejaculate irreversibly immobilizes 100 percent of spermatozoa in
less than 30 seconds.
It would be necessary to use only about 1ml of lemon
juice in the vagina to inactivate HIV and sperm.
Neat lemon juice applied to the vagina, or the penis
and foreskin is not in any way painful to the user if no lesions are
present.
Lemon juice might also be very useful for post-coital
washing of the penis, particularly the foreskin, to protect men from
HIV infection. If lemons are in short supply, lime juice would be a
good alternative.
