The potential benefits of CBD to human and even animal health is a prominent topic of current research and discussion.

When we explain the effects of CBD, it is very important to understand the different types of extracts.

Cannabidiol (CBD) is extracted from the cannabis plant in various forms. The different extraction methods used in different products directly determine the different effects and effects of CBD on the body. Before buying or using it, we recommend that every consumer must understand the differences between them.

Full Spectrum CBD (Full Spectrum), Broad Spectrum CBD (Broad Spectrum), Isolated CBD (Isolate) and PCR CBD are the four common forms of CBD extracts.

They contain types of cannabinoids and synergistic plant extracts. To help you find and choose products that suit your needs, we have compared and studied these four types of products to understand the differences between them, and understand how these differences affect your CBD intake.

Full spectrum

The full spectrum or whole plant cannabis extract maintains the integrity of the cannabis plant. In addition to CBD, this extract also includes terpenes, cannabinoids, vitamins, minerals, fatty acids, phytonutrients and any other substances extracted from the hemp plant. The hemp plant naturally contains more than 100 cannabinoids, similar to CBD, they provide unique benefits.

The full spectrum extract contains all the available benefits of cannabinoids. By maintaining all plant ingredients, the whole plant cannabis extract benefits from the synergistic properties between the various cannabinoids. Scientists have discovered that plant ingredients interact to produce an enhanced effect (compared to individual ingredients).

According to a theory called the entourage effect, CBD and other components of hemp work together to improve absorption and effectiveness in the body. These compounds affect each other’s functions, and the sum is greater than their parts.

Due to the integrity of natural cannabinoids, the whole plant hemp extract contains a small amount of THC. However, according to the regulations on industrial hemp, the whole plant hemp extract must have a THC of less than 0.3%. This is a hallucinogenic dose.

Broad Spectrum CBD

Broad-spectrum CBD is basically a full-spectrum CBD that contains a series of cannabinoids and terpenes, but does not contain tetrahydrocannabinol (THC). If you want to maximize the benefits of CBD without the risk of failing a drug test, this is a good choice.

Broad-spectrum CBD is manufactured by passing the product through an additional process to separate and eliminate tetrahydrocannabinol (THC) while still retaining other natural cannabinoids and terpenes. Since a variety of cannabinoids and other compounds are protected in the broad spectrum of CBD, it can provide the enhanced benefits of entourage without the mental effects of THC.

An example of this is cannabis oil tincture, which is full spectrum but does not contain THC. Let us explain the manufacturing process of this product.

Hemp oil tincture starts as a full-spectrum oil. There are various methods of extracting the full spectrum of hemp oil from the hemp plant. Although CO2 extraction is considered the cleanest method, other methods such as solvent extraction can also be used. Regardless of the extraction, the final product will be an oil with varying amounts of THC not greater than 0.3%.

At this point, most manufacturers will use this oil in combination with several other ingredients or use it as is. Using a technique called Centrifugal Partition Chromatography (CPC), manufacturers of cannabis oil tinctures have taken an extra step.

CPC is a tool to purify cannabis extract. CPC technology separates each compound to remove unwanted compounds, such as THC.

During CPC, crude oil runs through centrifuges. Push the oil through a series of cells containing a mixture of liquids, such as water, methanol, or heptane. Each compound diffuses into a liquid based on its affinity for each other; these compounds separate into different cells along the way.

The compact CPC device uses more than one thousand extraction cells in the high-speed rotating disk group to separate and purify the desired compounds. Each cell increases the purity of the desired compound until a high-purity product is produced. Additional CBD isolate is then added to the final product to increase effectiveness.

Separated CBD

CBD isolate is the purest form of cannabidiol. To produce this extract, the CBD is separated and then refined to remove any other cannabinoids, terpenes and plant components found in the hemp plant. The final product is a fine white powder containing about 99% cannabidiol.

The isolate contains only one cannabinoid: CBD. This means that CBD isolate does not contain any THC, a psychoactive cannabinoid with hallucinogenic function, making CBD isolate a perfect choice for people looking for THC-free products.

The isolate has no taste or smell and can be used to formulate a variety of CBD products, such as food and topical products. Since the purity of CBD separation is about 99%, you can precisely control the amount of product added (one milligram of CBD isolate is equivalent to about one milligram of CBD).

When it comes to products such as vape juices or tinctures, if the color is very clear, it is easy to identify them as CBD isolates. Although other ingredients can be added to darken the liquid.

PCR-Phytocannabinoid Rich CBD

Phytocannabinoid rich cannabis oil or PCR is a term most commonly used to describe cannabis oils containing various cannabinoids and OTHC. In other words, PCR is a commonly used alternative term for broad-spectrum cannabis oil. However, it is important to note that PCR is generally used in general terms and can also refer to full-spectrum products, which contain up to 0.3% THC.

If CPC technology is available, you may wonder why all products are not THC. THC is an intoxicating compound of the cannabis plant, and it attracts the attention of those who do not want to experience cannabis poisoning or who have to participate in routine drug testing.

Although beneficial for these reasons, THC is also studying its interaction with CBD, which we call the accompanying effect.

A note about broad-spectrum CBD or full-spectrum products without THC

Please note that not all products with full-spectrum or THC-free labels will be produced in this way. We recommend that you be vigilant about products that claim to be full-spectrum and THC-free. In many cases, THC-free “full spectrum” products only contain CBD isolates. If in doubt, please refer to the manufacturer’s COA (Certificate of Test) to determine the cannabinoid content in the product.
