These trichomes are tiny, hair-like crystals that cover the leaves and buds of the cannabis plant. Trichomes product the hundreds of known cannabinoids that can be found in cannabis. Of the 100+ cannabinoids that have been identified in the cannabis species, CBD and THC have been studied the most extensively for their role in the endocannabinoid system.

Having a medical condition is difficult enough, but if that condition doesn’t respond to medical treatment, life can become a constant battle. Refractory epilepsy is also known as uncontrolled or drug-resistant epilepsy. This means that a person who is suffering from refractory epilepsies is not responding to traditional medicine and thus is unable to effectively manage his or her neurological disorder.


People who experience psychosis may produce too much or even too little cannabinoids (from overactive dopamine receptors). CBD is milder than our internal cannabinoids and helps to re-establish a balance of cannabinoids in the brain. CBD also helps lower inflammation, which is often increased in schizophrenia. THC, on the other hand, is stronger than our internal cannabinoids (anandamide and 2-AG), this way potentially triggering psychosis [46, 48].

If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.
Improving the appearance of the skin, especially reducing the signs and symptoms of acne and eczema, are the great benefits of regular CBD oil use. Topical application is quite popular for this, whether in a diluted or undiluted form, depending on the severity of the skin affliction. The powerful anti-inflammatory properties of the oil can also soothe redness, itchiness, and swollen areas of the skin.
CBD may be best known for its relaxing, calming effects. CBD reduces autonomic arousal, having the inverse effect of THC on the body. CBD’s anti-anxiety effect is why many in the cannabis community talk about how CBD relieves paranoia, although that is not scientifically proven yet. CBD is also known for its anti-nausea and pain relieving effects. It really depends on why your body’s specific needs and the quantity in which you take CBD.
It’s safe to say that Charlotte’s Web is probably the most recognized CBD brand out there — and it’s not all hype. This company pioneered the CBD industry and made it their mission to de-stigmatize CBD by setting the bar high for transparency. They produce and oversee their organic CBD products from seed to sale, standing behind them with a solid return policy. 

A major theme when reviewing the research on the best CBD for pain is the need for more large-scale clinical trials on CBD in isolation from other cannabinoids like THC. That’s not to say that THC is bad. It’s developed a stigma because it makes you high, which makes people think of hippies and the sixties and maybe your perennially stoned neighbor who clearly doesn’t have his stuff together. But THC also comes with a pretty respectable list of benefits. These range from antiemetic (anti-nausea) and anti-inflammatory effects to appetite stimulation.
CBD oil is not legal everywhere. It is banned/restricted by countries such as UAE, Dubai, and Saudi Arabia. Although CBD oil is illegal in many of the US states too, some have legalized its use for medicinal purposes. While the number would be ever-changing, as of 2016 there are 17 states in the US which have legalized the use of low THC, high CBD products for medical reasons in limited situations. These states include Alabama, Georgia, Iowa, Kentucky, Florida, Mississippi, Louisiana, Missouri, North Carolina, Oklahoma, South Carolina, Wisconsin, Wyoming, Tennessee, Texas, Utah, and Virginia. It is advisable to consult your local health specialist before use.
Cannabidiol hemp oil, or CBD hemp oil, is made from high-CBD and low-THC hemp, unlike medical marijuana derivatives that often contain high quantities of tetrahydrocannabinol (THC). CBD hemp oil, a natural botanical extract of the common hemp plant, is therefore non-psychoactive. And, whereas in the cannabis plant CBD is the second most abundant cannabinoid after THC; in hemp it dominates the cannabinoid makeup, as THC is found only in trace amounts. CBD’s myriad of health benefits, however, are still present.
Researchers at the Department of Pharmacognosy, The School of Pharmacy, University of London, UK, basis the study conducted on mice found that CBD oil has analgesic properties and may relieve chronic pain of all kinds . It can disrupt the activity of pain receptors in the body and instead cause a release of neurotransmitters such as serotonin and dopamine – “feel good” compounds that can ease discomfort and pain, even if the pharmaceutical painkillers have no effect.
The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.
What you gain from Full Spectrum CBD is called the “entourage effect.” Studies have suggested that CBD is most effective when it’s combined with other cannabinoids. Each cannabinoid has its own properties and confers its own benefits. Working together, a synergy is created that boosts the healing properties of CBD. Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
CBD is suddenly everywhere — and it’s not hard to see why. It won’t get you high, has a good safety profile, and naturally treats dozens of conditions. But there’s a dizzying amount of choice out there, so we’ve ranked the 25 best CBD oils to help you get started.  Whether you’re a rank beginner, or you’ve been experimenting with CBD for a while, we’ve got you covered. 

Social media is blasting this one out lately, showing that different parents have been treating their children illegally (in states that are not classed as medical states) to help prevent their children from having seizures or deal with epilepsy. While there has been limited scientific evidence on the topic, 2016 was a major turning point for the plant as a major study was conducted by Orrin Devinsky, a neurologist at New York University Langone Medical Center, showing profound results.

High blood pressure is a globally ubiquitous issue. This study explores the connection between CBD and a reduction in blood pressure. It is particularly unique as it is noted that “there are no dedicated studies in humans to date, to our knowledge, looking at the effect of CBD on either resting cardiovascular measurement or on the responses to stress, with continuous monitoring of CV parameters.”

Author Gerhard Nahler found it most surprising that an entire group of authors were “tempted to over-interpret results.” However, he felt that misinterpretations are not entirely uncommon, stating “People overlook quite frequently that “in vitro” results may differ significantly from conditions “in vivo”, particularly in man. In vitro results are suggestions, not proofs for processes in real life.”
Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.
When it comes to using CBD, questions keep coming up, especially from people who try CBD for the first time. Since there are different CBD products and because CBD can be used in different ways, the question of how to use CBD oil is quite legitimate.  What CBD products are available, how they can be used, and the bioavailability of each product is covered in this article.
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.

It makes no sense to me that something that helps with anxiety has an irritability side effect – as a lot of my anxiety is co-mingled naturally with irritability. Further, I have noticed none of these side effects, given that if you become fatigued or sleepy, you adjust dose the next day. So I don’t call that a side effect – rather – an effect of taking too much.
