..I still have a few doses but just in case I started a batch:
-250ml jar
-2/3 full with Blue Vervaine dry with stalks
-Ice cold Vodka to fill half way
-then drizzle cold soda water till almost no space left
-cap it, leave a room temp
Everclear is better but all I had is Tequila so no matter what just adjust the ratio for Everclear..
The stems contain the most active ingredient but if you make two batches you can use the first batch starting the next day and use the pulp left over as poultice since it hasn't been fully extracted..
We have discussed many tricks in the past including using Ozone and Vinegars to speed up extraction.. all lost to CIAoogle...
