I read an article about arganine vs lysine. The tests they get this info off were done in a test tube and not on humans. There was also another study done on mice with herpes. Mice die from herpes and when they gave the group of mice higher arganine than the 2nd group, it actually kept them alive longer than the group not given it. I was taking lysine until recently and I've noticed no difference and I eat a vegan diet which is higher in arganine. The only thing lysine seems to do is stop the itchy tingling feeling I get but then again that might be in my head like the placebo effect.
When I had my first and second outbreak of genital hsv1, I had a weird thing happen with my throat. The first time which was 2 days before the sores appeared, I woke up in the night unable to breath because my throat felt like it had closed up. The second time it happened it was the same thing but much milder.
