I mix cocoa powder, turmeric, black pepper, and enough extra virgin olive oil to form a smooth paste. I then add hot water and it forms a suspension and the oil mostly doesn't separate out. I think the bitter taste and the fact that all the ingredients are plausibly active makes it an effective placebo, even if it turns out not to actually do anything.
