STEP 1<br />
Preparing Plant Material<br />
Grind the plant material to a fine powder. The finer ground the material the better your yields will be. The<br />
best technique to pulverize and rupture the cell structure of any plant material is to repeatedly freeze and<br />
thaw it over and over again. An example of a plant requiring this treatment is Phalaris arundinacea, a<br />
strong and limber grass. Mimosa hostilis root-bark is easily pulverized to a fine powder in a blender,<br />
releasing a pink haze.<br />
