How To Make CBD Oil From Industrial Hemp?

Making CBD oil from industrial hemp is a complex and delicate process, but if you have the necessary knowledge, skill, and equipment you will be able to pull it off without too much difficulty. 

Cannabidiol (CBD) is one of the many phytochemical compounds that are found in hemp. CBD has several therapeutic uses, some of which are still being investigated. So far, studies have shown that CBD can be used effectively to treat the following things:

  • Pain
  • Inflammation
  • Anxiety
  • Depression
  • Nausea and vomiting
  • Seizures
  • Insomnia

CBD oil is made by extracting CBD from hemp flowers and mixing it in a carrier oil, such as coconut oil. The carrier oil increases the CBD’s ease-of-use without affecting its potency. CBD is lipophilic, meaning it binds to fats, and can only be mixed in a lipophilic carrier oil.

There are two basic methods of extracting CBD from hemp, and they are ethanol extraction and CO2 extraction. Both methods use a solvent that is passed through the plant material and extracts the CBD. The solvent is then eliminated from the extract to make sure that it does not leave any impurities behind.

Ethanol Extraction

This is a fairly common method of extracting CBD oil from industrial hemp because it can be done at home with minimal equipment. In this method, alcohol in the form of ethanol is used to extract the CBD. Ethanol is affordable and it has low toxicity levels, which makes it an ideal substance for this process. With that being said, other forms of alcohol can also be used. 

There are two methods of using ethanol to extract CBD from industrial hemp. The first one uses room temperature ethanol while the second one uses “supercooled” ethanol. In the former, the ethanol is at room temperature so it preserves more terpenes in the CBD. On the other hand, supercooled ethanol makes the process work faster but it also withdraws most of the terpenes from the CBD oil. It’s also worth noting that supercooled ethanol is more affordable than warm ethanol extraction.

C02 Extraction

This method of CBD extraction uses pressurized carbon dioxide to extract CBD. When carbon dioxide is subjected to high pressure it liquifies. This liquid carbon dioxide is passed through the hemp plant material, where it acts as an agent to separate the cannabinoids from the plant material and eventually evaporates. CBD that is produced with this method has high purity levels, but it requires expensive equipment and it has to be done in a lab setting. As such, it is best suited to a large-scale production setting.

How Much CBD Is In Industrial Hemp?

The amount of CBD oil in industrial hemp will depend on how the hemp was cultivated. Hemp that is cultivated for industrial purposes may have small amounts of CBD because of the reasons outlined below.

When hemp is cultivated for industrial use, the emphasis is placed on fiber production and not cannabinoid production. Consequently, the plants are grown close together to ensure that the stalks, which contain fiber, grow tall, thin, and remain soft. The buds and flowers containing the CBD, on the other hand, may not grow as large. 

If you want to grow industrial hemp for CBD production, it’s a good idea to allow the colas to grow large and dense. This way, the CBD levels will be higher.

It’s also worth noting that CBD oil from industrial hemp will have lower levels of tetrahydrocannabinol (THC). Legally, industrial hemp must have less than 0.3% THC. There are a few things that a farmer can do to ensure that the THC levels remain low.

Since THC levels are so low, CBD oil from industrial hemp is non-psychoactive and will not make you intoxicated. It is also very safe for human consumption even when used in high doses.

How To Store CBD Oil Made From Industrial Hemp

CBD oil is best stored in dark-colored glass bottles away from direct sunlight. Brown bottles are ideal as they will block sun rays, which can destroy terpenes and CBD. The shelf life of CBD oil is 1-2 years.
