Herpes Simplex Virus

Herpes simplex virus (HSV) is a member of the human herpes virus group that includes, for example, herpes simplex virus-1, herpes simplex virus-2, and Epstein-Barr virus (EBV). Herpes simplex virus is a recurrent viral infection that remains dormant in the nervous system with periods of reactivation characterized by individual or multiple clusters of fluid-filled vesicles at specifically affected sites. Herpes simplex virus-1 and -2 are the main types of herpes virus seen in general clinical practice. Herpes simplex virus-1 typically manifests above the waist and is referred to as Herpes labialis because of it primarily appearing on the lips in the form of “cold sores.” Herpes simplex virus-2, Herpes genitalis, typically appears on the genitals, although it also produces skin lesions. The vesicles rupture, leaving small, sometimes painful ulcers, which generally heal without scarring, although recurrent lesions at the same site may cause scarring. Coinfection with herpes simplex virus-1 and -2 increases the frequency of herpes simplex virus-2 outbreaks. Orogenital sex can lead to cross-contamination of these sites, with oral herpes being more likely transmitted to the genitals than the other way around. The incubation Read more […]

Antimicrobial Plants And Immunomodulators

Herbal tradition includes many infection-fighting plants. Many of these plants are now known to contain various immunomodulating fractions, particularly polysaccharides, as in licorice (Glycyrrhiza glabra) root and the popular echinacea (Echinacea spp.) roots or seed heads. Both plants can be taken as decoctions of the roots, as herbal tinctures or in combination with other herbs in a formula. Licorice is an underutilized herb in viral infections in Western botanical practice especially in children who typically enjoy its taste. Licorice has not been well studied in influenza but drew much attention in the deadly sudden acute respiratory syndrome (SARS) epidemic. An herbal formula containing licorice was dispensed to 3,160 at-risk hospital workers during the epidemic. None of those taking the formula contracted the disease compared to 0.4% among those who did not. Another study looked at the antiviral potential of certain constituents against coronavirus from patients with SARS. Glycyrrhizin from licorice was the most active and successful at inhibiting replication of the virus. Licorice, of course, has a long folk history of use to treat coughs and inflamed throats, providing needed symptom relief in influenza. Echinacea Read more […]
