How does CBD oil works?

CBD is a powerful plant extract that has been used for wellness for thousands of years. Herb40 CBD is derived from a specific strain of the hemp plant. It is one of many cannabinoids in hemp that has a variety of effects on our body’s endocannabinoid system. We actually have receptors and compounds in our bodies that interact with the compounds that naturally occur in hemp. Watch this 20 minutes video wich explains how CBD works in detail.

What are CB1 and CB2 receptors?

CB1 and CB2 receptors are G protein-coupled receptors that are found in the walls of the cells in various organs in our body.
These receptors form what has been termed the endocannabinoid system, which is a network that forms a signaling pathway to impact a wide range of physiological processes. 

How does CBD make you feel?

CBD can have either a calming or an uplifting effect, depending on how your body interacts with the substance.

What are Cannabinoids?

Cannabinoids are a type of organic compound produced by the cannabis plant and were named as such as they were thought to be unique to the plant. There are currently 118 known Cannabinoids found in the Cannabis plant, of which two are found in high quantities, THC, and CBD. Other more prevalent compounds are CBC and CBG.

When consumed by humans, Cannabinoids interact with receptors found in the walls of cells in certain organs in our body.  Activation of these receptors seems to trigger chain reactions that alter chemical processes and neural signaling in humans. 

What is the entourage effect?

While not clinically proven, the leading scientific researchers in the Cannabis field have coined the term to describe the synergistic manner in which cannabinoids and terpenes work together to produce the effects that Cannabis Sativa L induces.
This is reinforced by research on individual compounds such as CBD and THC that do not produce effective results in treating conditions such as pain, inflammation, and appetite individually.

Is CBD and hemp oil the same thing?

CBD and hemp oil are made from different parts of the plant. Typically, hemp oils are made from pressing hemp seeds whilst CBD is extracted from hemp (Cannabis Sativa L.), flowers, and leaves.

How is CBD extracted from hemp?

There are several ways to extract the valuable compounds from Hemp. The most common methods used by commercial producers are:
Liquid Solvents: Usually Butane, isopropyl alcohol, hexane, or ethanol, they are passed through the plant matter to remove cannabinoid and flavours. They are then transferred to the liquid which is, in turn, evaporated away to leave concentrated chemicals and flavours in oil form. There are however some concerns surrounding this extraction method as Liquid.
Solvents can leave trace impurities.
CO2 Extraction: Utilizing a ‘Closed Loop Extractor’ this form of extraction is very gentle and is fast becoming the preferred extraction technique. CO2 can exist as a solid, liquid, or gas this allows for variables in pressure and temperature to be manipulated to extract the compounds that you require and discard the ones you do not. Unlike extraction using Liquid Solvents, there is minimal risk of contaminants.
Water Extraction: New techniques are emerging that retain more of the plant’s beneficial compounds. Cannabinoids and Terpenes are extremely temperature and pressure-sensitive, therefore cold-water extraction enables the retention of a much greater proportion of these compounds through the extraction process, and therefore a better end product.

Inhalation offers higher absorption rates, and is generally faster acting, but does not last as long.
Herb40’s unique formulation and encapsulation mean that there is no need for our oil to be left under the tongue but would not do any harm if you did.

When is the best time to take CBD?

There is no ‘perfect’ or ‘optimal’ time to take CBD as every individual is different and many report differing effects.

On the other hand, some individuals report that CBD has a relaxing effect and prefer to take it in the evening or before bed.
It may be best to see how CBD works for you and adjust the time you take CBD accordingly. 

How long does CBD take to get into your system?

This varies significantly depending on the mode of application. Inhalation will result in CBD entering the bloodstream within a matter of minutes.
The sublingual application may take a little longer.

It is always best to err on the side of caution as many countries have very stringent controls and penalties for the procession of Cannabis in any form.

What proof is there that CBD is effective? Is there research?

There are a large number of both animals and human trials studying the mechanisms and benefits of CBD. While these trials cover the potential treatment of a wide scope of conditions, there are not many full-scale clinical trials, therefore these indications are just that for now.
