I am not familiar with herbs and has to depend on my naturopath, who is a master herbalist. But I will suggest to him some of your mentioned items.
I let my wife drink ozonoated water after she did a session with MWO. Not sure if this is enough. The nearest ozone therapist for me is in neighboring malaysia. They asked for USD$10,000 deposit just to see my wife. I am afraid this is beyond me.
And I have access to ozonoated olive oil. Not sure if it can be applied directly to the tumour and not causing pain.
