I have fresh herbs. I plan to dry it and according to protocol i need to use methanol to insolate the useful compound in herb which maybe have the anti-bacterial 's functions. Some journal do mentioned that using distill water, but the product might not have anti-bacterial's functions.

I plan to use herb. I just want to make the normal soap for hand washing. according to my finding, the solvent which can use is methanol..But I understand methanol hardly removed by heat. and the solvent will be harmful to skin.

I plan use prepare soap using plant extract. But during the sample extraction, methanol will be added. What is the best way to remove methanol? how to make sure that methanol are removed from the extract?
