Drugs like foscarnet, a pyrophosphate analog, and cidofovir, a nucleotide analog, can be used when acyclovir-resistance has developed, although these drugs display reduced bioavailability and nephrotoxicity, respectively11,12,13,14. Smallpox was an often-fatal diseased cause by infection of human beings by the pox virus variola. The soluble ectodomain of herpes simplex virus gD contains a membraneproximal pro-fusion domain and suffices to mediate virus entry. The viral early proteins are generally involved in DNA replication where, for example, ICP8 stimulates viral DNA replication52,53.

HSV-1 is also associated with more severe infections in neonates, elderly people, patients with acquired immune deficiency syndrome, and patients with drug-induced immune suppression. The results are very compelling, and support the need to further evaluate the purified active ingredient in small animal studies., With smallpox, it is obviously impossible to see if this herb is effective in the human body unless a bioterror release of the virus occurs, says Langland. Call your doctor for medical advice about side effects. Often used as specific, as well as prophylactically (for more details about this remedy, see below). CAS & Schnitzler, P.

An old herbal remedy for treating smallpox that is thought to have been used by native Americans in the late 1800s has been rediscovered and found to kill the poxvirus. The extracts directly inhibit extracellular virions or viral attachment to the host cell as well as inhibiting the expression of ICP4, ICP8 and gC when added at various times post-infection.

As mentioned, the glycoprotein, gC, plays a vital role in adsorption of the virus to the host cell. S. purpurea inhibited HSV-1 induced cytopathic effect and replication. Virol. Sarracenia purpurea, commonly known as the purple pitcher plant, northern pitcher plant, turtle socks, or side-saddle flower, is a perennial carnivorous plant in the family Sarraceniaceae. Treatment with S. purpurea gave a dose-dependent reduction in viral titers with an approximate 3-log reduction at 40g/ml and a 4-log reduction at 60g/ml. Denzler, D. L., Huynh, T. P., Jacobs, B.

Since previous work using S. purpurea extracts against poxviruses demonstrated that the extract did not disrupt the poxvirus envelope34, we propose that the extract is likely blocking HSV-1 attachment to the cell, although further studies to confirm this are required. Our lab has previously demonstrated that extracts from S. purpurea have the ability to inhibit the replication of poxviruses by inhibiting early viral transcription34. PubMed Article Jeffrey Langland. 2022 Aug 22;12(8):1287. doi: 10.3390/life12081287. Version: 1.06.
