Wow, quite a mix of therapies you've got going on there! Clearly you've done a lot of research. I'm not well versed in the mushrooms, chinese herbs, or ginseng. But I don't doubt their potential to be therapeutic. Hopefully this strategy is what it takes, and your friend continues on this healing trajectory!
I don't know how legalization efforts there are, but here, we got tricked into MORE prohibition with our "legalization" in Canada (2018). Now it's 14 years in prison instead of 4, and there are far more offenses now than before. Even passing a joint to your 17 year old friend will get you thrown in prison for a long time. It's a corporate monopoly of insiders and profiteers. Peaceful growers and farmers market sellers are going to prison for something that is supposedly "100% legal". It's only legal for the state and their connected buddies. And the legal weed is very low potency, full of chemicals and pesticides that dissolve lung tissue when heated. Irradiated, not cured. Harsh and dead shwag at best. And it costs 5 times more than the black (free) market! That's why I say legalization is a lie and warn people that it isn't going to bring them the freedom they're being promised, and that they assume. It's all about controlling the people and the market.
