But you can just let the alcohol evaporate to yield your impure extract which then you extract with organic solvent, so miscibility isnt an issue.
BTW, "bitter agent" , which? Its important to know solubility to se if it isnt something that will come across to final product, or something that breaks down into a toxic compound when under extraction conditions, etc
Also, while methanol is toxic so dont drink it or breathe vapors, it is volatile, will evaporate (faster than ethanol), so if you make sure it is a clean methanol, work in well ventilated area and make sure your product is properly dry, using methanol isnt any problem.
