I find the placebo effect to be a fascinating topic, and I'm glad you touched on it and for the source you cited.
I found this review article a while back and I think it might compliment the Harvard source.
"In conclusion, we believe that the placebo effect is not imaginary. It is real as its neurophysiological basis is becoming known. Although the intensity and frequency of the placebo effect are difficult to determine in clinical practice, placebo should be taken into account by doctors and nurses as another therapeutic option that, alone or associated with other treatment, could be useful in certain circumstances."
