Homeopathy is when no single molecule of substance is present in your dose. Put a cup of coffee in ocean. And get a drop of ocean to get homeopathic remedy for sleep.

Microdosing is about taking as much as you can without hallucinations. Still works, still enough active molecules in your dose to make magic in your brain. It is usually like 1/10, not 1/1000000000

10% of a very potent dosage is hardly homeopathy.

As far as I know, the concept of homeopathy works on an "information level" (I wouldn't be too surprised if quantum physics are involved), not on the molecular/material level (which microdosing still does).

you're grossly uninformed. homeopathy is diluting something into a totally ineffective concentration. microdosing is diluting something into a concentration that is just barely below the threshold of easily noticeable effects, but well above the threshold of real but subtle effects.
