Genital herpes is a relatively common sexually transmitted disease (STD). In the United States, about 17% of the population is infected. This equates to about 50 million people, with a frequency of one in six women, and one in nine men afflicted.
Herpes is Causes by Two Viruses
Genital herpes is caused by herpes simplex virus I (HSV-1) and herpes simplex virus II (HSV-2). Both viruses cause clusters of blisters and ulcerations that are extremely painful and often reoccur. The viruses hang out in nerves associated with the skin, which protect them from the immune system between outbreaks. The infection is transferred by skin contact, especially from lesions, but sometimes from normal-looking skin.
Of the two viruses, HSV-1 is usually associated with cold sores around the mouth, and milder genital lesions. HSV-2 frequents the genital/anal region and causes more severe outbreaks. They both may be transmitted by intercourse and oral sex, even when one is asymptomatic. In fact, most people with the virus do not know they are infected.
Conventional and an Alternative Herpes Treatment
Conventional management of herpes relies on antiviral medication therapy in either episodic or suppressive roles. There are several medications available and they tend to reduce outbreaks by up to 70%. While currently effective, there are concerns that continual use will decrease their sensitivity. Allergic reactions occur rarely
Red Marine Seaweed May be an Option in Managing Herpes
Other options are emerging for those where the conventional approach is unavailable or not working. Red seaweed of the species Gigartina skottsbergii has been shown to inhibit HSV 1&2 infections in animal models. It apparently does this using polysaccharide compounds to block the ability of herpes virus to bind to, and enter cells.
Research continues, and industry is beginning to incorporate these compounds in products like condoms, with mixed success. Several supplement manufacturers are now marketing red seaweed supplements, usually with the label “red marine algae.” The challenge is that while there are many species called red seaweed, most of the research has been centered on G. skottsbergii.
Red Marine Algae Safety
For the moment, the FDA considers these supplements generally regarded as safe (GRAS). This is due to the ubiquitous nature of seaweed components as food additives. Concerns regarding iodine and carrageen-induced digestive inflammation may result in future changes. The standard anecdotal dosage of G. skottsbergii appears to be about 350 mg, taken one to three times a day, for at least a week. It is taken solely, or as augmentation to conventional medication. Though natural in origin, this substance should not be taken without direct physician supervision.
