HSV-1 is a highly infectious virus that causes the primary infection, herpes labialis, and establishes a latent infection in the neural ganglia1,2. It is hardy to UK zone 3. . Limited clinical trials for HSV-1 infection, performed by three different research groups, determined that a topical application of S. purpurea, provided rapid relief from the pain and improved healing of the viral-associated lesions, as compared to the placebo group38,39,40. Other drugs may interact with pitcher plant, including prescription and over-the-counter medicines, vitamins, and herbal products. 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. Jeffrey Langland. These results may suggest that constituents in the S. purpurea extract are potentially binding to the HSV-1 surface glycoprotein(s) and inhibiting viral attachment to the host cell or disrupting the virion envelope/structural integrity. & Bryson, H. M. A reappraisal of its antiviral activity, pharmacokinetic properties and therapeutic use in immunocompromised patients with viral infections. provided experimental design and interpretation. "Pitchers" have downward facing hairs. There is much scepticism on herbal medicine but what our results illustrate conclusively is that this herb is able to kill the virus and we can actually demonstrate how it kills the virus, says Langland. Hudson, J. 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. 1A, HSV-1 infection induced observable CPE after 24h. When virally infected cells were treated with increasing doses of the extract, this CPE was moderately to fully inhibited (Fig. But since the risk is so low for populations at large, it is hard to justify vaccinating everyone, particularly because the vaccine can have serious side effects. J. L.K., As.K., Ar.K. Our lab has previously demonstrated that extracts from S. purpurea have the ability to inhibit the replication of poxviruses by inhibiting early viral transcription34. CAS Free-virus treatment was performed using 200pfu of HSV-1 KOS treated with increasing concentrations of S. purpurea and incubation for 1h at room temperature.
