Smallpox has been eradicated, but the finding offers a possible treatment for poxvirus in the unlikely event of a bioterror attack or increased incidence of similar poxviruses such as monkey pox. Smallpox ravaged human populations for thousands of years, but in 1796 Edward Jenner discovered that exposure to cowpox lesions could provide immunity to smallpox. This led to the creation of the first vaccine for a disease. It took some time, but in 1979 the World Health Organization officially declared that smallpox had been eradicated. 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 Americans of Nova Scotia treated the disease using a botanical infusion derived from the insectivorous plant Sarracenia purpurea, a species of pitcher plant. Now, Jeffrey Langland at Arizona State University in Tempe, US, and colleagues have conducted in vitro experiments with the herbal extract and found it inhibits replication of the variola virus, the causative agent behind smallpox. Although, natural smallpox no longer poses a health threat, there is a remote possibility that unstable states or terrorist groups could have acquired stocks of the virus following the collapse of the Soviet Union, which had developed smallpox as a biological warfare agent. Vaccinations are still administered to at risk groups including researchers working with poxviruses and members of the US military who could potentially be exposed to the virus through biological warfare. 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. Developing therapies is therefore important in order to treat people if a bioterror event does occur. ’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. ’It takes this herb out of the realm of folklore, and into the area of true scientific evidence.’ The team made extracts of S. purpurea and found that it was highly effective at inhibiting the replication of the virus in rabbit kidney cells. They then looked at the replication cycle of the virus and found that the herb inhibits mRNA synthesis, halting production of proteins vital for replication. ’Other drugs are being developed against smallpox, but S. purpurea is the only known therapy that will target the virus at this point in the replication cycle,’ says Langland. ’The extract blocks early transcription appearing to have a distinct mechanism of action from that of two other antivirals currently in clinical trials,’ says Mark Buller, a virologist at Saint Louis University, Missouri, US. ’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. ’We are in the process of doing animal studies to confirm our results in at least this type of whole animal system.’ Reference W Arndt, PLoS One, 2012, DOI: 10.1371/journal.pone.0032610 Poster Comment: Pitcher plant Sarracenia purpurea is for sale on the Internet. Just copy and paste it into your search engine and add + price. You will see ads. Cheap. It can stop smallpox so it can stop the less threatening monkeypox. I would also take zinc 220 mgs a day to kill the virus. I would take ionophores to get the zinc past the lipid barrier of the cell wall so it can kill the virus. Quercetin and Green Tea Extract are ionophores meaning they carry zinc past the cell wall. I would also take a bolus of 50,000 IUs of vitamin D-3 until the fever passes. I would also take extra vitamin C and bioflavonoids. I take Quercetin (a bioflavonoid) daily with Zinc. It lowers blood pressure and helps the zinc kill viruses.
