Notes for this study:
In persons with inoperable tumors given either aged garlic extract (500mg daily) or placebo for six months, there was no apparent increase in quality of life associated with the garlic supplement yet an increase in both natural killer cell activity and content, although activity per cell was unchanged (so the increase in overall activity was just due to more natural killer cells).

It was noted that while 5 persons in placebo experienced a 25% decline in NK cell activity, none in the garlic group did. No increase in cortisol was noted despite an increase in control.
