Symptoms of genital herpes, HSV2, typically begin with pain, tenderness, or itching in the genital area and also include fever and headache.
In males, the blisters appear on the penis, and in females, the blisters appear on the area around the vagina and in the cervix. In both males and females the blisters may appear on the thighs and buttocks. Blisters soon erupt to form painful sores that last 1 to 3 weeks.
In many cases other symptoms may appear such as a pain or a burning sensation during urination; a clear mucus-like discharge from the vagina or urethra in females; a clear mucus-like discharge from the tip of the penis in males; and tender, swollen glands in the groin area.

Research has been conducted on Gigartina 4 in treating the Herpes Simplex Virus revealing that it stimulates an immune response that fights the virus and keeps it at bay.
