Ethanol hash oil (EHO)

Cannabis extract

Ethanol hash oil[ˈɛθənɒl hæʃ ɔɪl]

Definition:

As the term implies, ethanol hash oil refers to the cannabis extract produced using ethanol as the principal solvent. Ethanol Hash Oil is generally known by its initials, EHO, and comes in various textures and consistency.

Ethanol extraction works in warm or cold temperatures; however, cold temperatures preserve more cannabinoids and terpenes. Cannabis matter should undergo decarboxylation at low heat before proceeding with cold ethanol extraction to preserve cannabinoids and terpenes.

After soaking the cannabis flower in alcohol, the plant debris is extracted. Ethanol is vaporized before being condensed into the oil. Additional purification is required to achieve the same level of purity as a BHO or PHO; any leftover chlorophyll can provide a bitter or grassy flavor, as well as a dark coloring, both of which are undesirable.
