Treating West Nile Virus with High Quality St. Johns Wort


West Nile Virus, although new to the U.S., is well-documented. The Centers for Disease Control identifies it as a flavivirus, a member of the Togavirus family. It is closely related to yellow fever and dengue fever. This is important because the Togavirus family are encapsulated viruses, i.e., they are covered with a lipid (fatty) coating.

This is exciting, because it means the virus is accessible to treatment utilizing high quality St. John's Wort (SJW). Several studies have been done on a variety of encapsulated viruses, including herpes simplex virus types 1 and 2, parainfluenza virus, vaccinia virus, cytomegalovirus and several retroviruses including HIV1, 2, 3, 4, 8, 9, 10.

Non-encapsulated viruses or "naked" viruses were also studied for comparison purposes10,13.

SJW was a potent anti-viral agent across a variety of encapsulated virus families, but showed no activity against naked viruses.

Unlike a vaccine that is specific to each organism, SJW is active against encapsulated viruses by a variety of mechanisms, including light activation, interference with DNA transcription, impairing the assembly of intact viral particles and the lipophilic (fat-loving) nature of the ring structures (the quinone and phenolic groups)4, 6, 7, 9, 11, 12, 13, 14, 15. These ring structures are critical to the biologic activity of SJW.

From these results, it is reasonable to use high quality, pharmaceutical grade SJW in combating West Nile Virus, since there are no effective pharmaceutical agents.

Quality is critical since the level of hypericin and pseudohypericin are key. I can only recommend the SJW product produced by Medi-Herb, which is a pharmaceutical house in Australia, adhering to pharmaceutical manufacturing standards. The product is distributed by Standard Process through alternative health care practitioners, including doctors of chiropractic, acupuncturists and veterinarians. SJW is quite unstable and the active ingredients degrade on store shelves. An independent analysis of 3 products (all of which were certified to contain 0.3% hypericin) were shown to be widely variant, with one product 25% below label claims. It is critically important that the phytochemical integrity of the whole plant be preserved for maximum efficacy.16
