Hemp oil can be extracted from the seeds of all plants in the cannabis species, whether it's marijuana or industrial hemp but, industrial hemp is the only genus used for hemp oil.
The extraction process is done by pressing the seeds in the same way as flax or sesame oil. Hemp oil has a very low THC and CBD concentration. This is because the industrial hemp which is grown for seed oil does not naturally have high counts of THC and also the seeds have a much lower quantity of THC and CBD.
CBD in its purest form
CBD or cannabidiol is one of many cannabinoids present in cannabis. The isolate form of CBD is 99% pure and it is the most potent version available on the market. It can be found in crystal form or in a white fine powder that contains only the CBD chemical compound. This isolate version of CBD is an all-natural product, it’s not artificially made in a laboratory like other cannabis products.
