Plaque formation was visualized by staining with crystal violet. Similarly, when Vero cells were pre-treated with the S. purpurea extract, washed and then infected with HSV-1, no reduction in viral replication was observed (Fig. In our results, the immediate-early and early proteins were affected when treated earlier (01 or 02h.p.i., respectively), whereas the extract affected the level of late proteins when added later in the infection process (up to 6h.p.i.). Botanical name: Sarracenia purpurea Preparation.Prepare a tincture from the fresh root, in the proportion of viij. Med. S. purpurea directly inhibited the free virion or viral attachment to host cells, as well as inhibiting the expression of viral gene transcription. A botanical preparation, derived from the carnivorous plant Sarracenia purpurea, was proclaimed as being a successful therapy for smallpox infections.

This plant has been used in traditional medicine for a wide variety of medical illnesses, including smallpox infection, gynecological problems, diabetic problems, mycobacterial infection, and liver/kidney complaints34,35,36,37. Slider with three articles shown per slide. Pitcher plant taken by mouth has been used in alternative medicine to treat constipation, urinary tract problems, digestion problems, fluid retention, and other conditions. Google Scholar. S. purpurea reduced HSV-1 ICP4, ICP8, and gC protein levels in a time dependent manner. The level of HSV-1 ICP4, ICP8, and gC gene expression was analyzed by real-time PCR. Shukla, D., Liu, J., Blaiklock, P., Shworak, N. W. & Bai, X. For clarity, this concentration of the S. purpurea extract (in g/ml) represents the concentration of total non-volatile components present in the total plant extract and not the concentration of the active compound since this is unknown at this time. Samples with statistically significant deviation relative to the untreated HSV-1 sample are indicated with asterisks (*p<0.05, **p<0.01, ***p<0.005). Sex Transm. Google Scholar. The effectiveness of these drugs, however, are limited in immune-suppressed patients, resulting in increased likelihood of the virus to develop drug resistance9,10. Silica is a leading remedy for severe, chronic cases. The IC50 for the S. purpurea extract based on plaque reduction was calculated to be approximately 23g/ml and the CC50 using an MTS assay was calculated to be approximately 161g/ml resulting in a Selectivity Index of 7 (Fig. An extract of the pitcher plant Sarracenia purpurea halted viral replication Historical sources suggest that in the 1800s, when smallpox still posed a serious threat, the Micmac native . In addition, treatment with S. purpurea extract alone did not induce any noticeable cell toxicity (Fig. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions.
