ABSTRACT
In the context of cannabis, “oil” could refer to (1) “fixed” (vegetable) oil from the seed, (2) essential oil from the glandular secretory trichomes, or (3) “hashish oil,” i.e., solvent extracts rich in cannabinoids, particularly tetrahydrocannabinol (THC) (“liquid hemp” is a recent expression referring particularly to cannabidiol [CBD]-rich concentrates, especially for vaping; this is sometimes inappropriately called “hemp oil”). This chapter deals with the fixed oil from the seeds of Cannabis sativa; the essential oil from the flowering part of the species is discussed in Chapter 9, and hashish oil is discussed in Chapter 12. To avoid ambiguity, the oilseed industry often prefers the phrase “hempseed oil” rather than “hemp oil.” Although “hemp seed” and “hemp-seed” are often encountered, hempseed has become sufficiently familiar that its designation as one word is justified. Moreover, the term hempseed is parallel with other oilseed crops such as linseed and rapeseed.
