Hola Magico,
Firstly, as you probably already know, liver cancer is especially difficult to treat, usually with a poor prognosis, and I have no experience assisting somebody with that condition.
However, the 'cancer patient in my life' who has Stage IV metastatic breast cancer responded very well to a Syrian Rue tincture that I prepared, with formerly aggressive, treatment-resistant tumors subsequently becoming 'stable' despite the fact that the primary medication was no longer working and patient had been advised that the situation was likely to deteriorate soon. That was some time ago now, but the patient has 'never felt better' and is firmly convinced, that Syrian Rue has played a large part (if not the only one) in that. For mood-enhancement alone, which is obviously very important in these situations too, rue is excellent IMO.
I made a tincture using 120g whole seeds, pressure-cooked in 800ml water for 2 hours. Filtered. The same seeds were then soaked in 200ml 95% ethanol for 48 hours, and this combined with the water-extract, to make about 1 litre. I think grinding seeds brings only problems, and mucilage...
Dosage: 5 ml/day first week. Then 10 ml following week. Then 15 ml until spent. This minimised adverse effects of harmalas in somebody with no prior experience.
In your friend's case, the situation might be complicated by liver/enzymes/inhibition potentially affecting the tissue and other drug absorption. CBD might also be worth looking into, especially as it concentrates in fat, which pushes it towards the liver.
I also found that my patient observed positive changes soon after starting, because the metastatic tumours are in the spine (and affected mobility) and they reported increased mobility, after a lengthy period of decline and increasing pain, in that area.
As I guess you're not too far from some aya places in S. America, perhaps also look into some of the centres there, if funds/mobility allow? I personally think aya + a good curandero, can do some good things with some cancers...
But if rue is "talking" to you, just listen; she knows far more than we ever will!
Buena suerte!
“I sometimes marvel at how far I’ve come - blissful, even, in the knowledge that I am slowly becoming a well-evolved human being - only to have the illusion shattered by an episode of bad behaviour that contradicts the new and reinforces the old. At these junctures of self-reflection, I ask the question: “are all my years of hard work unraveling before my eyes, or am I just having an episode?” For the sake of personal growth and the pursuit of equanimity, I choose the latter and accept that, on this journey of evolution, I may not encounter just one bad day, but a group of many.”
