Which sub can help healing Giant-cell arteritis?

[Shannon]

Hey, I have a friend who's dad has Giant-cell arteritis.

You can see what it is here: https://en.wikipedia.org/wiki/Giant-cell_arteritis

Shannon, or someone, knows if there is any sub that could help him to get better?

I know there is the maximum healing speed, or MIR, but I'd to have solid advice before suggesting anything.

Looking forward for your answer,

Thank you in advance for your answer.

I am sick right now and having a hard time thinking coherently, so I can't be doing research or answering questions like this right now.
