fresh turmeric for s-IV NSCLC/adenocarcenoma while on Alimta - 1273042

I had a couple of questions about turmeric. I did a search first, but it seems that the most recent thread that's relevant to my questions is about 5 years old, so I thought I'd broach the question again.

My wife is a never-smoker who was diagnosed with stage-IV NSCLC / adenocarcenoma of the lung in September. She had 6 infusions of Carboplatin + Alimta, and is now getting Alimta maintenance. (Her main tumor is about 40% smaller now -- down from 6.4cm.)

Her regular oncologist at UCSF Mt. Zion gave her a referral to an "integrative oncologist" across the street. (He's so much in demand that the first opening he had wasn't until earlier this month -- almost 5 months after she got the referral!) This oncologist is an expert on all kinds of supportive treatments and regimens that help cancer patients, from diet to meditation to acupuncture. Having become familiar with my wife's case, he recommended a variety of things, including some specific medicinal mushrooms, and turmeric / curcumin.

However, we were surprised to learn that he was unaware that fresh turmeric was available; he presumed she would just take a supplement. Consequently, he could not recommend a specific amount of turmeric to add to her daily fresh vegetable juice (carrots, ginger, black pepper, cucumber, celery, etc.) I've been juicing a piece the size of a pinky finger, but don't know how that might compare to the effective amount in a supplement. Searching around on-line didn't result in anything useful.

Any never-smokers with NSCLC out there who use turmeric in any form (with the approval of their oncologist)? Anyone know anything about what a recommended amount might be for juicing? Any input would be appreciated.
