Customer Service: We’ve always received fast, informative responses to our queries about products and practices, but there are definitely customers out there who have not. A quick perusal of reviews shows customers who had issues with unaddressed orders. It’s hard to know exactly what the problem is in these situations, but the company’s strict return policy (seven days for unopened products only) probably doesn’t help. It should be noted that the company has a solid base of very satisfied customers as well.
Moreover, scientists at the Cajal Institute showed promising results in regards to CBD and Multiple Sclerosis. They used animal models and cell cultures to find that CBD reversed inflammatory responses; within only ten days, mice that were used in the study had superior motor skills and showed progression in their condition. To date, there have been well over 20,000 published scientific articles on cannabinoids and their related effects on all sorts of medical ailments.
Many people are tempted to believe that products that contain CBD only are the best, thinking that using just CBD alone is a more effective treatment. While products that contain single-molecule CBD, meaning that you won’t find any other compounds, are already provided as medicines, they are not exactly more efficient than whole plant extract CBD oil, when it comes to therapeutic effects. 

Another point worth clarifying is the difference between hemp seed oil (or hemp oil) and CBD oil. There’s confusion on this point for the very good reason that both CBD oil and hemp seed oil are extracted from the industrial hemp plant. But there’s a big difference between the 2. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things — it’s good for you, tastes great, and can be used in soap, paint — even as biodiesel fuel.
The cannabis plant contains a unique group of carbon compounds often referred to a phytocannabinoids. The most common ingredient is THC, which creates the euphoric high effect. Due to the THC element in the plant, marijuana is often associated with a stoner stigma of people only wanting to get high. But that is far from the truth. Cannabis also contains other medicinal compounds including cannabinol, cannabigerol, cannabidiol, and cannabichromene.
However, switching to CBD oil from a conventional medication is far from a random stab in the dark. In fact, there was a large scale (and very well-documented) survey carried out less than two years ago that looked at precisely what percentage of patients were able to “swap” their side effect-inducing meds for a 100% natural, cannabis-based therapy.
When administered alone, CBD is an effective anticonvulsant in maximal electrical shock (MES), magnesium-free, 4-aminopyridine, and audiogenic models (7, 8). Co-administration with AEDs leads to various effects; anticonvulsant effects of CBD are enhanced with phenytoin or phenobarbital but decreased with chlordiazepoxide, clonazepam, trimethadione, and ethosuximide. In a recent study using an acute pilocarpine model, although CBD administration reduced the number of animals displaying seizure activity, CBD did not appear to have any significant effect on the number of seizures per animal (7).
CBD can be applied to the skin both as a cream and as a concentrate or tincture. When you apply CBD Concentrate to the skin, you do not need to apply as much as the cream because of the higher concentration of CBD. Due to its gluey texture, it will adhere very well to the skin and if the CBD oil has a dark color, it will give a stain. Just leave it on as long as possible. If necessary, you can easily remove the remaining concentrate with edible oil from the skin.
CBD was also found to disrupt the consolidation of generalized fear memories when administered immediately after the acquisition of such fear memory. Interestingly, the timing of the administration of CBD was vital as the results demonstrated that delayed administration of the CBD dose did not have the same effective result that immediate administration did.
A number of difficulties exist in evaluating published data on CBD or marijuana use for epilepsy. The extremely limited published studies were small, poorly described, and not well designed. Contributing to the difficulty of interpreting published studies, CBD products are not produced under the guidance of good manufacturing practices (GMP) and are not subject to regulations governing labeling, purity, and reliability. In other words, currently, there is no guarantee of consistency between products, or even differing lots produced by the same manufacturer. Without independent testing (e.g. USP certification) of CBD products for content and purity, as well as bioavailability testing of specific products, uncertainty surrounds the use of available CBD products in routine clinical settings.
A natural plant extract, CBD (or cannabidiol) has made a huge stir in the health scene over the last decade. It’s not hard to find plentiful anecdotal evidence of its benefits — people are using CBD for pain relief, mood regulation, cancer prevention, even seizure reduction. But if you’re in pain, you’re probably looking for more than anecdotal evidence. We get it — and we’re here to help.
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.
Of course, there is a different side to the story also. It is true that the studies concluded so far have their limitations, and there is no saying what effects supplementation with CBD for more than 6 months could have. However, they suggest cannabidiol has the potential for treating some mental disorders, like anxiety and depression, seizure disorders like epilepsy, insomnia, and chronic pain.
Another field in which CBD is creating a buzz is in the area of mood disorders like anxiety and depression. Both conditions have been treated with a variety of medications, courtesy of Big Pharma, that have had varying levels of success. Again, the long list of side effects can be off-putting to someone who just wants to get through the day without the sweaty tension of anxiety or the gray haze of depression.

From what I understand, CBD derived from the hemp plant does not have the side effects mentioned above, other than possibly to help reduce the amount of Coumadin/Warfarin needed – either way, a patient on this drug needs to be monitored and regularly tested anyway with their doctor. CBD derived from the marijuana plant (will contain THC) may have them, I do not know, maybe that’s why you mention them. One of the many reasons people take Hemp CBD is that it does NOT have the side effects! People take the Hemp version to help with feelings of fatigue, irritability & anxiousness, it does cause it! It helps to bring the body into balance.

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.
Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
Generalized pain, for instance, has dozens upon dozens of high profile research and clinical studies that have been carried out in universities and laboratories around the globe. One of the most well-publicized of these studies took place back in 2008, in which results determined that “cannabinoid analgesics (pain relievers) have generally been well tolerated in clinical trials … with acceptable adverse event profiles (meaning acceptable effectiveness for practical use).
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.
Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, PhD, director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”
However, even if you do suffer from one of the above-mentioned chronic conditions, it’s still recommended you start out with the low potency oil first, at least until you gauge how your body reacts to the CBD. It’s important to understand that because everybody’s biochemistry is different, not everyone will react the same or get the same therapeutic effects from CBD oil.
