Some people may refer to CBD oil as hemp oil because it is obtained from the hemp (cannabis Sativa) plant. These two are very different products.
Hemp is often used in describing non-intoxicating cannabis that is harvested for its derived products’ industrial use.
CBD, or cannabinoids, is a chemical compound within the hemp plant. CBD oil is made by extracting the compound from the plant’s flowers, leaves, and stems, then mixing it with carrier oils such as hemp oil or coconut oil.
Hemp oil is a natural oil extracted from hemp plant seeds. The hemp plant is a cannabis Sativa plant but a different variety from marijuana.
Benefits of CBD oil
Some of the benefits below are better supported by study than others. These are just some of what the current research says.
CBD effect on the immune system receptors may contribute to the overall reduction of inflammation in the body. A study published in the Journal of Clinical Investigation established that CBD oil restricted activity in the sebaceous glands.
The glands produce sebum, a fatty substance that hydrates and lubricates the skin—acne results from excess sebum production.
Researchers suggest that CBD may make alterations to the way your brain receptors react to serotonin. Serotonin is a chemical that is accredited to happiness and the body’s well-being. It also regulates anxiety and moods. It is a natural version of depressants.
During a study at a public-speaking event, participants who took CBD reported feeling less anxious. We concluded that CBD is a promising solution for panic disorder and social anxiety disorder. However, CBD oil is not recommended for long term anxiety treatments.
Pain and inflammation treatment
The human body produces neurotransmitters called endocannabinoids, which link to the cannabinoid receptors in your nervous system. CBD may contribute to pain reduction by influencing the receptor activity of endocannabinoids.
Studies have proven that CBD can relieve pain to a great extent when administered after chemotherapy treatments. Your brain receptors’ reaction to CBD helps you manage pain. Nonetheless, researchers believe the CBD in drugs projects its anti-inflammatory properties more than act against the pain.
CBD has been reported as a possible remedy for epilepsy. Though studies aren’t clear how CBD reduces epilepsy, the oil is known to have several biochemical impacts on the brain’s nerve cells, some of which may alleviate seizures.
CBD oil may be beneficial to people fighting drug addiction. However, the oil’s effect on each type of addiction is different.
A study performed by scientists from the University of Montreal gathered that CBD “showed promise” in treating cocaine or opioid addiction. From the study, opioid addicts exhibited little changes in withdrawal symptoms after using CBD. Meanwhile, CBD showed significant outcomes in minimizing drug-seeking habits in cocaine addicts.
Research also suggests that CBD could be significantly beneficial in the treatment of marijuana addiction.
CBD may reduce the risk of heart failure by lowering blood pressure. Researchers decided that anxiety-relieving traits of the oil are responsible for the decrease in blood pressure.
Cancer patients support
Research is increasingly supporting the effectiveness of CBD in managing some symptoms that accompany cancer treatment. These symptoms include pain and nausea.
CBD oil extraction methods
Olive oil method
In this method, cannabis plant stalks are heated with olive oil to draw out the cannabinoids.
Carbon dioxide extraction
The type of extraction is done by exposing the hemp plant to cold, high-temperature carbon dioxide gas. The CO2 gas helps separate and preserve the cannabinoid products in the oil.
However, this method is slow and time-consuming. This inadequacy means the resulting CBD oil is bound to be expensive.
Ethanol extraction is safe when done in small amounts. The major downside of this method is that it damages the plant waxes resulting in health benefits.
These compounds significantly help in cannabinoid extraction. However, they leave some residues after the process is complete, which can potentially harm your lungs.
How to take CBD
CBD can be extracted from cannabis plants in oil or powder form. Either can be mixed into capsules, gels, or creams. Therefore, you can take them orally, sublingually (under the tongue), or smear them onto your skin.
Orally taking CBD capsules allows consistent and regulated doses over time. Sublingual administration enables a fast onset of action for the cannabinoids, whereas a direct smear on the skin acts instantly on the injured or inflamed part.
It is safer to seek your doctor’s advice before using CBD oil in any of those ways.
Possible side effects of CBD
The oil doesn’t have high health risks but can trigger the following side effects:
• Alterations in appetite
• Dry mouth
CBD and Cytochrome P450
Research shows the CYP450 enzyme group does the activity of metabolizing CBD and other cannabinoids. However, CBD inhibits the performance of CYP3A4, the specific enzyme that performs the task.
CYP3A4 metabolizes around 60% of clinically prescribed drugs. Therefore, CBD inhibiting the performance of CYP3A4 means the enzyme won’t work effectively in breaking down the drugs in your system. Slow metabolism in your body may indicate more medication in your body than should be, even if it’s your regular dose.
CBD and sedatives
When CBD interacts with neurotransmitter receptors in the central nervous system, the effect can be sedating to the user. CBD mixed with sedatives can increase the effect of the drugs. The increase is referred to as the additive effect.
Despite all these, you should avoid combining the oil with sedatives as its full potential impact on sedatives isn’t entirely known.
More health studies are needed to fully understand CBD oil, its risks, and its side effects. CBD studies are limited, partly because cannabis products are highly regulated, a significant drawback for researchers.
Hemp seed oil
Hemp is a species of the cannabis Sativa plant that contains 0.3% or lower THC, the psychoactive component. The seed oil is obtained from the cannabis plant seeds. Like its source, the seeds, the oil is famous for its abundant omega-3 fatty acid content and other nutrients like protein.
Though extracted from the cannabis plant, the hemp seed oil is not used for recreational purposes. The oil cannot get one “high.” This incapability is because of the small percentage of THC, the compound responsible for the psychoactive effects.
Benefits of hemp oil
Hemp seed oil makes an excellent skin moisturizer because:
• It prevents moisture loss from the skin
• The skin absorbs it quickly
• It is rich in nutrients and antioxidants
• It offers relief from minor abrasions
Promotes hormonal balance
Hemps seed oil contains about 9% gamma-linoleic acid (GLA). This acid is necessary to synthesize prostaglandins, which are similar to hormones that regulate many body functions. Researchers have concluded that using hemp seed oil may boost hormonal health and minimize PMS symptoms such as back pain.
The hemp seed oil can also improve hormone health in women undergoing menopause and minimize associated symptoms, e.g., depression and irritability.
The GLA in hemp seed oil can help reduce inflammations. This property makes the oil beneficial to people with inflammatory diseases such as arthritis.
Helps in weight loss
The gamma-linoleic acid in hemp seeds is a natural appetite suppressant that helps you control how much you eat, resulting in weight loss. GLA can also reduce sugar cravings. It is common knowledge that sugar is a great contributor to weight gain; therefore, hemp seed oil can help cut weight.
Hemp seed oil is rich in fatty acids and proteins, which add to moisture, strength, and hair growth.
Enhances brain function
The oil also contains omega-3 and omega-6, compounds known to enhance brain functions, and promote healthy aging of the brain.
Hemp seed oil extraction
Presently, there are five extraction methods of hemp seed oil extraction;
Soxhlet extraction method
The Soxhlet is the most conventional process of hemp seed oil extraction. It is also a popular method used in oil extraction.
Supercritical fluid extraction (SFE) with carbon dioxide solvent
Supercritical fluids have a superior ability to dissolve materials like a liquid and effuse through solids like a gas.
Percolation (PER) method
This method is based on leaching, where molecules are drained out of material. This technique is not commonly used in hemp seed extraction.
As the name implies., this method employs ultrasonic frequencies. It has the advantage of a reduced extraction time resulting from the double effect of chemical and physical separation.
Pyrolysis is a thermal decomposition method for bio-oil extraction. This process is not popular in the extraction of hemp seed oil.
How to take hemp seed oil?
Hemp seed oil is extracted from cannabis plants in oil form. It can then be mixed into capsules, gels, or creams. You can take them orally or smear onto your skin. Seek your doctor’s advice before using the oil.
Hemp seed oil interaction with medication
Currently, there is limited literature citing hemp seed oil interaction with medication.
The legal status of CBD and hemp seed oil
CBD’s legality has made extensive progress as it is now allowed in 47 seven states in the US. It is only in Nebraska, Idaho, and South Dakota, where CBD oil is prohibited.
Differences between Hemp seed and the CBD oil
Hemp seed oil and CBD oil are not the same products, though from the same plant.
CBD oil is obtained from the stalks, flowers, and leaves of the cannabis plant. These plant parts are rich sources of CBD. On the other hand, hemp oil is extracted from the seeds of the same plant.
CBD oil may be relatively new to many consumers, but hemp seed oil has been around for ages.
The notable difference between CBD and hemp oil is the parts of plants from which they are extracted. Hemp seed oil is extracted from the hemp plant seeds, while CBD oil is extracted from the plant’s flowers, leaves, and stalks. Their method of extraction also varies. If not, the two aren’t too far apart.
