A friend of Stella’s, I’ll call her Kate, rescued an injured raven and was nursing it back to health. The raven was living in her home. Right around this time, Kate was having memory problems, headaches, and disorientation. She consulted the doctors and was diagnosed with a brain tumor. Being holistically oriented, she tried various herbs and cleanses to no avail. The symptoms worsened. Finally she decided to try a radical treatment called escharotic therapy.

Escharotic therapy, often used for cervical dysplasia, starts with putting a salve of blood root and other herbs over the tumor site. If you look it up on line, you will find stern warnings like this. Here is a description of the therapy from Wikipedia:

Other formulations include the four ingredients: red clover, galangal, sheep sorrel, and bloodroot, crushed into a paste using mortar and pestle. Pseudoscientific practitioners advise that this is applied sparingly to the affected area, and kept covered for 2–3 days, although this treatment has not been proven to work for any medical application or to be safe.
