Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.

“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.


The main thing to consider when figuring out how to find the right strength CBD oil is to realize that everyone’s internal biochemistry is different – while your friend may be able to relieve her anxiety with just a single 3 mg dose, you may require several times that much in order to obtain the same results. Or, you may not find any relief at all. This is why it’s important to start off with the smallest possible dose, and work up from there.
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.”

Other potential side effects include low blood pressure, lightheadedness, and drowsiness, but these have typically only occurred in patients who have exceeded doses of 1,500 mg daily for a period of 4 weeks or more; far more than the average person will need take on a daily basis for chronic pain symptoms. (In fact, the majority of CBD users claim they find an effective dose to be anywhere between 10 and 40 mg daily).


The 600 mg oil is a good “step-up” option for people who find that they’re having to take large (and/or multiple) doses of the 300 mg in order to get effective results. In general, a lot of people use this strenght for more moderate cases of anxiety, pain, inflammation, and digestive issues. A single dose is still the same 15 drops of oil, but instead of containing 7.5 mg of CBD, a 600 mg bottle will contain 15 mg per dose.

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.
While it is still classed illegal on a Federal level, individual U.S. states have adopted a more lenient policy towards this plant and some states now allow it for recreational use. The easing up of state laws has also allowed researchers to explore this miraculous plant and only recently has it been found to be an effective treatment for a variety of medical problems due to its CBD oil benefits. From cancer, anorexia, pain and inflammation management it seems like medical marijuana is placing a strong footing within the medical industry.
You are likely very familiar with the dangers that prescription painkillers (and other pharmaceuticals) present. In fact, it’s estimated that the majority of CBD oil users attempt to switch to the all-natural therapy for the precise reason of kicking prescription med habits, which all too often cause an overwhelming array of irritability, sleep disruption, digestive complications, and even thoughts of suicide.
Although I’m no physician, and am not qualified to recommend any drugs for any specific medical purposes, and you should consult your doctor when considering the consumption of anything that may be medicinal: If you’re looking to experiment with CBD products, you might consider looking for CBD products that are “whole plant” extract based from very high CBD cultivars. If you’re in a State that has a legal Cannabis system, you may also find more therapeutic benefits from non-hemp derived CBD products.

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.


The interest and preference for botanical remedies such as CBD oil over harsh pharmaceuticals are growing rapidly. You can read scientific research on the promise of CBD Oil at NCBI. While North America is taking the lead legalizing cannabis and hemp the rest of the world is starting to question their stance on prohibition because of the undeniable benefits. While all talk about plant-based remedies may seem very new, using cannabis/hemp tinctures as a holistic remedy is a generations-old tradition. It was very common to use tinctures of cannabis oil in the eighteenth and nineteenth centuries. We are enjoying a renaissance in ancestral health where we are open again to remedies that were all but forgotten about in the mad race to make medicines a pill offered by a faceless often unaccountable corporation.
While animal experimental data clearly suggest a potential benefit, supportive clinical data are quite sparse. In a case-control study of 308 cases of new onset seizures, Brust and colleagues found that marijuana use was significantly less prevalent among men who had unprovoked seizures compared to case controls (9). This difference was not significant in women. The authors suggest a potential protective effect against seizures with marijuana use; however, this should be considered speculative.

Deciding to use CBD oil as a natural therapy is one thing – figuring out which brand to use, what strength/concentration to use, and how much CBD to actually take is another thing altogether. Plus, with all of the products out there to choose from and their confusing mL/mg labels, it can be a nightmare trying to determine which one is best for you, or which one you should be taking for your specific condition.

Cannabis has always been a popular form of treatment for a variety of medical conditions, but in the 1930’s growing concerns about the dangers of marijuana abuse led to cannabinoids being banned. A century has past and despite all efforts from cannabis enthusiasts through social media channels and online media, cannabis is still classed as a schedule 1 drug.
