I dont like taste of ABV either. So i do a few extra steps to ensure i am getting as much of the bitter waxes out of the final product.
First prefreeze ABV and Alcohol separately for few hours. Then mix together ,put just as much to cover the material,dont put too much cause it will take longer to evaporate. After that simmer it for 20-30-40 minutes (you can toss it in the freezer while it simmers ) and strain trough a strainer or cheese cloth and then trough a coffee filter. IMO cheese cloth(i actually use large medical gauzes ,instead of cheesecloth) is better because you can actually squish it and get more out of it than using a strainer. After straining trough a coffee filter ,let it sit for few hours in the freezer and strain again trough a coffee filter ,to remove more of the bitter stuff.
Then proceed to evaporation. If you want to make a tincture to use with an eyedropper,dont evaporate the alcohol fully ,just simmer it down to the desired consistency.
If you wanna mix it with coconut oil which can be used both for topicals ,lubricants and edibles,then u must evaporate all the alcohol prior that. Put few tablespoons of the coconut oil along with the extract and apply some heat ,via double boiler method or else.
After the oil mixes with the coconut ,you can further dilute it with fresh virgin coconut oil ,which hasnt been heated. This is the key to both have the benefits of the unheated virgin coconut oil + the extract .
-------------------
As for water curing prior extraction ,i think it would add too much of extra work, cause you have to let it sit for a day in room temp water and after that you must strain and wait for it to dry.. If you have the nerves to do it you can further save on the bad taste .
------------------------------------------------
If you are feeling lazy,fuck prefreezing , just mix the ABV with Alcohol ,let it sit for 30-40 minutes.. ,then strain ,evaporate ,mix with coconut oil or use as tincture.
------------------------
As for absorbtion trough skin, it is possible but you will need DMSO for that,which can be quite dangerous,if you havent washed the place you apply it ,cause you can transfer crap into your bloodflow.
