It really depends on the "medication". Some are downright charlatanry like
http://www.oscillo.com/about/facts-about-oscillo/ <<< sells in "natural food" stores for $30-ish
200C means "original" solution diluted 1:100, repeat the process 200 times.
In simple math that results in 1: 10000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 0 concentration.
Yes, that's 1 followed by 400 zeroes... 1:10^400 concentration
The estimation is that there are 10^80 -ish atoms in the observable universe.
That crap is sugar without any trace whatsoever of the "ingredient".
