Cancer, Black Salve, Broccoli

Can you give me any information on a herbal product [Black Salve] which apparently comes from Canada that is used both as a salve and tonic for the treatment of cancer and other problems?

For an excellent discussion on black salve, please see the following link:

I would also like to point you in the direction of broccoli used topically for skin cancers and the results are surprising even the biggest skeptics. Please see:
