Cannabis products are much in the news currently and there can be confusion about the names of the various types of extracts. Different strains of cannabis plants contain varying quanities of two main active compounds: tetrahydrocannabinol (THC) which is pyschoactive and non-psychoactive cannabidiol (CBD).
Hemp oil (also known as hemp seed oil) is a is a vegetable oil extracted from the seeds of Cannabis sativa. It is available in capsules as a food supplement and is of low toxicity.
Cannabidiol (CBD) oil is produced from the flowers, leaves and stalks of Cannabis sativa. CBD oil is reported to have antianxiety, antipsychotic, anticonvulsant, antispasmodic and antibacterial properties.
Hash oil (also known as cannabis oil) is an oleoresin extracted from cannabis or hashish. It is a concentrated form of the plant containing THC, CBD and other cannabinoids. It is derived from any part of the plant and can cause typical effects of cannabis exposure.
Cannabis flower essential oil (also known as hemp essential oil) is obtained by steam distillation from the flowers and upper leaves of hemp (Cannabis sativa). The essential oil is manufactured from both low-THC (fibre-type) and high-THC (drug-type) varieties of hemp but since most of the phytocannabinoids are poorly soluble in water, hemp essential oil contains only traces of cannabinoids. Hemp essential oil is used as a scent in perfumes, cosmetics, soaps, and candles. It is also used as a flavouring in foods, primarily sweets and beverages.
