What is CBD or Cannabidiol?
CBD, also known as Cannabidiol, is a chemical compound of the cannabis plant family. The cannabis plant family is made up of hemp and marijuana. These variations vary in terms of the cannabinoids they contain in their leaves and stems and so they also vary in terms of their chemical effect on the human body.
The hemp plant contains the cannabinoid CBD or cannabidiol which is a non-toxic cannabinoid. The hemp plant is therefore used to extract CBD from and use in products like CBD oils, hemp creams and edibles like CBD Gummies or sweets. This trait of CBD and the hemp plant itself makes it safe to use in food supplements like CBD oil as it is non-toxic.
The marijuana plant on the other hand contains the cannabinoid THC or Tetrahydrocannabinol in large amounts. THC is the chemical compound found in the cannabis plant family which causes a ‘high’ effect. Although the hemp plant also contains THC, the levels are so low that we can say it occurs only in trace amounts.
Thankfully CBD products in Ireland effectively eliminate the possibility of any ‘high’ by using the hemp plant to extract cannabinoids from and so THC only occurs in trace amounts or sometimes not at all. Rest assured these trace amounts are too low to cause any sort of toxic effect, making CBD products safe and non-toxic to humans.
How does CBD work in the human body?
You may be wondering how CBD works within the body. CBD works in reaction to the body’s ECS which stands for Endocannabinoid System. This system was discovered by a scientist in the 1990’s when studying the effects of the cannabinoid THC. It was discovered that this system is always active within the human body and within animals’ bodies too.
The ECS is a signalling system between cells and includes the use of receptors, endocannabinoids and enzymes. Endocannabinoids are made naturally by the body and work to regulate bodily functions such as sleep patterns, moods, pain and inflammation, skin health and the reproductive system among others. They can also be referred to as neurotransmitters.

The ECS is complicated and still being studied by researchers to understand the full function of this system. We do know however that endocannabinoids made by the body bind to specific receptors when something is out of balance with our health. They work together to target a certain pain for example and afterwards enzymes act to break the endocannabinoids down.
Cannabinoids which are structurally very similar to the endocannabinoids made by the ECS are present in the cannabis plant. One of these cannabinoids which we mentioned is CBD. CBD therefore acts as an endocannabinoid does and binds to receptors in the body to regulate organs or bodily functions which have become unbalanced.
How does CBD affect the brain?
The receptors present in the endocannabinoid system are found in the CNS (central nervous system). CBD impacts the CNS by binding to the serotonin 1A receptor which targets brain function. In this way CBD can be seen to affect the brain in a few different ways but there has been limited research undertaken so far using clinical trials.
The research is slowly increasing however as the popularity of CBD does also. Visit CannaArchives to view the most up to date library of clinical trials involving CBD. A lot of anecdotal evidence is available online, however. I personally have seen positive effects on my brain function through the use of CBD both from a once off dose and from continued use. Ways in which CBD can affect the brain include:
CBD as a cannabinoid is known to act as an antioxidant. Antioxidants for those who don’t know are made naturally in the body and are also found in certain foods. They act to eliminate free radicals which can build up in the body and possible cause oxidative stress.
Oxidative stress is the cause of severe changes in the body and can lead to stroke, heart disease and other chronic disorders. The presence of antioxidants so ensures the blood is cleaned of free radicals regularly and lessens the risk of oxidative stress occurring.
CBD as a food supplement is known as an antioxidant as are foods like kale, spinach, dark chocolate and blueberries. Those who do not include such foods in their diet regularly may have an excess of free radicals built up inside their bodies. Using CBD as a health food supplement on a daily basis can aid the fight against oxidative stress and maintain a normal level of free radicals.
Decrease Brain Blood Flow
Many health issues associated with the CNS result from increased blood flow in the brain. Migraines for example can present with an accompanying ‘aura’ which affects your sight for a temporary amount of time. Personally, aura causes spots to appear in my line of sight which quickly change from one spot to many until I can barely see at all.
My GP once explained to me what is happening in the brain when this form of migraine occurs. She said that the blood vessels in my brain are opening and closing at a rapid rate which then interrupts the brain’s signal to the eyes. The first time I took CBD oil was when I was in the middle of a migraine with aura and within minutes the spots began to clear rapidly and my sight returned. The level of migraine pain I experienced halved compared to past migraines.
The blood flow level in the brain is reduced when CBD is present. This affects those who suffer from anxiety also as increased blood flow occurs in the brain when a person becomes anxious essentially feeding the anxious thoughts present.
Reduction in Excitotoxicity
Excitotoxicity refers to the brain cells becoming over-stimulated and damaged. Neurodegenerative disorders of the CNS can result in excitotoxicity occurring such as MS (multiple sclerosis) and Alzheimer’s as can brain injury trauma, and stroke.
Epilepsy, which has been strongly linked to CBD use in both anecdotal claims and clinical trials, also causes excitotoxicity to happen in the brain. The hope is that the intake of CBD could reduce the progress of this over-stimulation and ultimately reduce the level of damage caused in the brain.
Can I take CBD everyday as a health supplement?
You can take CBD as a daily health food supplement and in conjunction with a balanced food diet. CBD is not meant to replace any particular source of vitamins or minerals in your diet but rather acts as an additional supplement to an already healthy intake of food and nutrients.
How do I add CBD to my diet?
Adding CBD to your diet is very easy, even more so recently as further forms of CBD appear on the Irish CBD market. The most common form of CBD product is CBD oil which can also be called a tincture.
CBD oils come in a variety of strengths which refer to the level of CBD content present in the oil. Some brands specialise in low-strength oils while others offer a wide variety of strengths to consumers. Typically, CBD oil for humans starts at 2.5% CBD (250mg) and can range up to 30% CBD (3000mg).
Other forms of CBD include CBD gummies, CBD capsules, CBD cream or balm, CBD paste and even CBD chewing gum. So, as you can see it is very easy to add this popular, natural food supplement to your daily food diet.
