The alchohol evaperates leving only the extracted calea Z resin.
The alchohol basically breaks down the cells walls and allows the oils from inside the plant to combine with the alchohol. Now just set the stuff out and let the alchohol evaporate, which will happen quickly beacuse alch. evaporation point is so much lower than water or oil...
So now the goo is basically the left over oils of the plant and desolved plant matter..
