Found this last night:

Native American Remedy to kill poxvirus ’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.

Smallpox symptoms include a high fever and rash. It usually takes about 12 days for smallpox symptoms to appear after being infected.4 Early symptoms can include headache, backache, and fatigue. Vomiting might also occur. Approximately two to three days later, a red rash appears over the skin. This rash turns into fluid-filled blisters that later fill with pus. The rash then scabs over, the scabs fall off, and it leaves scars.
