After all, all that you need to produce quality dry sieve hash is a few good screens to filter out the plant matter, good starting material, and a little bit of time. The level of quality is often determined by amount of plant matter and capitulate trichome stalks found in the final product.
Fortunately, there are often plants. When plants absorb water from the ground they filter out many impurities, and you can extract this clean water from them. Plants transpire water, meaning that water vapor evaporates from the leaves, and this water can be collected.

Concentrated pharmaceutical preparations of plants obtained by removing active constituents with a suitable solvent, which is evaporated away, and adjusting the residue to a prescribed standard.
The toxicity of plant part extracts was also concentration dependent. At 1 and 2% (w/v), the inflorescence and leaves caused more root inhibition than stem extract. Parthenium shoot incorporated in soil at 1% (w/w) caused significantly more root inhibition of wheat than soybean, corn, and ryegrass.
Antioxidant extract yield from raw material, lemon balm leaves (ARM) was 0.4 g extract/100 g plant material. When the ground supercritical solid residues (ASR) were used, yields of 0.6 g extract/100 g supercritical solid residue were obtained, independently of the extraction pressure.
