Since opening the San Francisco office of Parsley Health in 2016, I’ve become exposed to the wide world of cannabis. I grew up in the midwest and had adopted conservative views of marijuana use. Despite living in California for almost two years, the first state to legalize medical marijuana in 1996, I was still skeptical of marijuana and CBD oil benefits. I was also hesitant to prescribe CBD to patients due to potential psychoactive effects when combined with THC and because it’s not a regulated substance. But as my patients at Parsley Health kept asking me about CBD, I decided to dig a little deeper into potential CBD oil benefits and was surprised at how promising it may be.
CBD oil has a wide range of effects on health and has been connected to a diverse number of health problems, ranging from migraines and stress to lack of appetite and sex drive. CBD oil has even been connected to reducing the risk of certain cancers, as well as reducing pain, improving the conditions of the heart, and helping people get a good night’s sleep. There are a number of ways to use CBD oil, depending on what you want relief from.

Pharmacists have since moved to metric measurements, with a drop being rounded to exactly 0.05 mL (50 μL, that is, 20 drops per milliliter) - https://en.wikipedia.org/wiki/Drop_(unit)1oz is 30 mL1000mg/30mL = 33.3 mg/mL CBD concentration20 drops * .05 mL/drop = 1mL10 drops * .05 mL/drop = .5mLyou take 33.3 mg in the morning and 16.65mg at nightI might suggest taking 50mg in the morning: 50mg / 33.3 mg/mL = 1.50 mL 30 dropstry it for a couple days and see how it helps
There are more than 80 cannabinoids found in cannabis plants, with THC being the primary one, followed by CBD. However, in the hemp plant, which is a different strain of the species Cannabis sativa, CBD is the main active ingredient, and THC is barely present, making its use and legality more widespread. The reason that CBD is such an effective form of support for human health is due to the body’s endogenous cannabinoid system. This regulatory structure of the body has millions of cannabinoid receptors in the brain and nervous system, which react not only to plant-derived cannabinoids (such as hemp and marijuana) but also to natural cannabinoids produced within our body. When hemp oil is used and processed by the body, it is effectively boosting the function of the endocannabinoid system, helping our body regulate itself in many different ways.
And now, onto the thorny issue of legality. The simple answer to the question is yes – if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called  “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.
Nora Volkow from the National Institute on Drug Abuse reiterated the decision of (then) two dozen states to allow medical marijuana to be used in one way or another in their jurisdictions. This should open everyone’s eyes to the sanctioning of a non-addictive, non-psychoactive substance which has been linked to benefits for patients suffering from seizure disorders, quite a few neurodegenerative disorders or pain resulting from cancer.
Two additional studies in this area were done using CBD oil. In the first one, 214 participants would take 0.9 to 2.3 grams of oil per 1 pound of body weight. CBD successfully reduced seizures by a median of 36.5%. The second study focused on children who suffered from Dravet syndrome. Dravet syndrome is a type of epilepsy that happens in early infancy. Normally high temperatures and fevers trigger it. The results of the second study showed that CBD oil reduced seizures significantly.

All MRI reports remained stable until November 2013 when my quarterly MRI came back showing regrowth of the tumor. My brain surgeon in Los Angeles recommended 4-6 months of chemotherapy, and if that didn’t work, another brain surgery to go in and clean up the regrowth would be considered. He also gave me anti-seizure medication for auras that had started to manifest as strong unexplainable odors. My doctor described this experience as an olfactory seizure. While researching Christopher’s Web cannabis oil as an alternative to the prescribed seizure medicine I also found out that cannabis oil was also showing promise as a cancer treatment and could be an alternative to chemotherapy.
Hi Ben. What are your thoughts on the differences, if any, between CBD extracted from hemp (legal to buy for anyone in the US) and CBD extracted from medical cannabis? My instinct is that once extracted, they should be identical because we’re talking about a specific molecule (similar to how ascorbic acid extracted from an orange or bell pepper or made in a lab are identical). However, I had some CBD oil from a major retail website that did not do much for my insomnia, even at high doses. Then I tried some CBD oil from my medical marijuana doc that he claimed was pure CBD (meaning no THC, but I am not sure if there are other terpenes) and of higher quality because it was extracted from medical grade cannabis. I was totally skeptical, but ending up feeling it big time – very calming, almost like being high, but without the random racing thoughts that THC gives me. I am wondering if it’s worth it to shell out for my doc’s product (it is super expensive), or if I should just try another version of hemp-based CBD, such as the one you recommend.
So your plasma concentrations of THC increase when you’re using CBD, resulting in a greater amount of THC available to receptors and increasing the effect of THC in a dose-dependent manner (which means the more CBD you use, the more THC becomes available). But along with this increase, CBD also acts as an antagonist at the a cannabinoid receptor called GPR55 in the caudate nucleus and putamen sections of your brain, reducing paranoia-like effects or heart-beat racing from weed.
It’s also nearly impossible to overdose on CBD. Kind of like water, dark chocolate, and steamed kale, it has an unusually low level of toxicity. In the last 6,000 years, CBD hasn’t killed anyone via overdose, which is particularly impressive when you compare it to non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, Advil and Tylenol, which can wreak havoc on your gut lining, liver and kidneys. Or aspirin (salicylic acid) which kills over 1,000 people every year. Or alcohol, which kills over 110,000 people a year. No one’s ever died from CBD.
While normally I'd be slightly tripped up by little things like an overly crowded subway car or a full inbox at work, the CBD oil seems to have taken the edge off of my anxiety a bit. Rather than overthinking a sternly worded email or analyzing a social interaction, I've found it easier to recognize the irrationality of these thoughts and actually let them go (instead of ruminating on the situation). In some ways, I feel more like myself. With that said, I've still experienced some social anxiety when meeting new groups of people—I'd be interested to see what taking the full recommended dose would do.
Due to the anti-inflammatory properties of cannabidiol, insulin resistance (the chief metabolic problem for patients with type 2 diabetes) is reduced, leading to a better prognosis thanks also to the lower incidence of dead tissue. Ever since the discovery of CBD in the 1990’s, speculation existed to its effect on other types of receptors (not just cannabinoid receptors) which could be manipulated and included in the treatment of some cardiovascular diseases like atherosclerosis. In light of these speculations, researchers at the University of Tel Aviv (walking in the footsteps of the “father” of cannabinoid research, Dr. Raphael Mechoulam) demonstrated a 30 percent blood flow increase in rodents with areas of dead tissue in the heart muscle.[22]
Relevant studies are summarized in Table ​Table3.3. In a SPECT study of resting cerebral blood flow (rCBF) in normal subjects, CBD reduced rCBF in left medial temporal areas, including the amygdala and hippocampus, as well as the hypothalamus and left posterior cingulate gyrus, but increased rCBF in the left parahippocampal gyrus. These rCBF changes were not correlated with anxiolytic effects [102]. In a SPECT study, by the same authors, in patients with SAD, CBD reduced rCBF in overlapping, but distinct, limbic and paralimbic areas; again, with no correlations to anxiolytic effects [104].

In a series of placebo-controlled studies involving 15 healthy volunteers, Fusar-Poli et al. investigated the effects of CBD and THC on task-related blood-oxygen-level dependent functional magnetic resonance imaging activation, specifically the go/no-go and fearful faces tasks [109, 110]. The go/no-go task measures response inhibition, and is associated with activation of medial prefrontal, dorsolateral prefrontal, and parietal areas [111]. Response activation is diminished in PTSD and other anxiety disorders, and increased activation predicts response to treatment [112]. CBD produced no changes in predicted areas (relative to placebo) but reduced activation in the left insula, superior temporal gyrus, and transverse temporal gyrus. The fearful faces task activates the amygdala, and other medial temporal areas involved in emotion processing, and heightened amygdala response activation has been reported in anxiety disorders, including GAD and PTSD [113, 114]. CBD attenuated blood-oxygen-level dependent activation in the left amygdala, and the anterior and posterior cingulate cortex in response to intensely fearful faces, and also reduced amplitude in skin conductance fluctuation, which was highly correlated with amygdala activation [109]. Dynamic causal modeling analysis in this data set further showed CBD reduced forward functional connectivity between the amygdala and anterior cingulate cortex [110].


Mike, what kind of breast cancer (invasive ductal, I presume)? How many of her lymph nodes were positive? How big was the primary tumor? Reason I ask is that in women with Stage I or IIA tumors that are estrogen-and progesterone-receptor-positive and HER2-negative (ER+/PR+/HER2-) with three or fewer positive lymph nodes, there is a genomic assay test on a sample of the tumor, called OncotypeDX, that will tell doctors whether chemo is necessary or would even work at all. Medicare covers that test 100%.That type of breast cancer mentioned above, which I had as Stage IA, is treated in postmenopausal women with anti-estrogen drugs called aromatase inhibitors(aka AIs: anastrazole, letrozole, or exemestane)which have as a side effect joint pain. CBD oil is effective for this joint pain it is not, I repeat, NOT a substitute for chemo, radiation or these anti-estrogen drugs.So don’t assume your mom’s cancer will require chemo; but if it does, CBD helps with those side effects as well. If she lives in a state where medical marijuana is legal, there are doctors who sub-specialize in certifying applications for a medical marijuana card, and in the interim before the card is issued can advise as to the appropriate dose of CBD oil (legal and over-the-counter in all 50 states). Some (though not most) medical oncologists will certify their own patients’ medical marijuana card applications so she need not seek out another doctor; and will advise the appropriate dose for her symptoms. Once she gets her card, the “budtenders” in the licensed dispensaries can advise her as to the right CBD product (with or without THC), strength, and dosage. If she lives in a state where recreational weed is legal, the “budtenders” in the marijuana shops can steer her to the right strength of CBD oil and the right dosage.
Anxiolytic effects in models used: CER = reduced fear response; CFC = reduced conditioned freezing; CFC extinction = reduced freezing following extinction training; EPM = reduced % time in open arm; ETM = decreased inhibitory avoidance; L-DT = increased % time in light; VCT = increased licks indicating reduced conflict; NSF = reduced latency to feed; OF = increased % time in center; SI = increased social interaction
CBD oil refers to a natural botanical concentrate that is derived from the seeds and stalks of cannabis plants. This oil has a high concentration of cannabidiol, also known as CBD. Out of the identified cannabinoids in the cannabis plant, cannabidiol is the second most common after THC or tetrahydrocannabinol. However, unlike THC, cannabidiol is non-psychotropic. That means it’s use does not cause the euphoric high effect like traditional marijuana and THC products do.
I have not read all 220+ comments, so perhaps this issue was raised, but I have read in multiple sources that hemp plants and marijuana plants are not the same. Various sites claim that this issue is confusing consumers and they state that (industrial) hemp plants tend to be low CBD and lack the full spectrum of cannabanoids, terpenes and other chemicals. They caution consumers to purchase only CBDs derived from female flowered marijuana plants if they want the full health benefits. They also state that CBDs in isolation do not work as well as when they are coupled with THC and other cannabinoids and terpenes. (Nature always knows best.) Your product is derived from industrial hemp plants according to BioCBD’s website. You have addressed the issue of the female flowers (thank you), but I am still very confused about this issue. Can you clarify? Thank you. P.S. I, personally, won’t be able to use your product because I am sadly allergic to turmeric, but I appreciate the information you have presented here. I will have to wait for another company to manufacture a water soluble product with a different carrier.

I suffer with migraines, fibromyalgia, and arthritis. I pretty much hurt anytime I move. I’m on a regimen of meds, but ordered the Virgin Cannibis Hemp Oil (off of Amazon) and have had it two days. I took 3 tablespoons a day, gagging it down. I couldn’t bring myself to take it today, but I didn’t notice a difference after the second day, and I suppose I would notice something. Was it too soon, or should I be trying a different product? I really need something to alleviate the level of pain during movement, as it’s causing me to be more sedentary.

Cannabidiol oil is extracted from the varieties of cannabis plants that have CBD occurring naturally in large amounts and THC in low amounts. To ensure a high concentration of CBD in the oil, a specialized process is used to extract the compound. The oil contains other compounds like terpenes, omega-3 fatty acids, amino acids, chlorophyll, vitamins, and phytocannabinoids like cannabigerol, cannabichromene, cannabidivarin, and cannabinol.

As mentioned previously, while CBD-dominant products help some people sleep, in others it promotes wakefulness. Orally administered THC, especially products from heavier “Kush” strains and Purple cannabis varieties, are very effective for sleep disorders. These tend to be high in myrcene and linalool, a terpene shared with lavender and known to be effective for relaxation. Cannabis combinations with ratios of 1:1, 4:1, or 24:1 CBD:THC can be used when patients want to reduce psychoactivity.

When it comes to treating anxiety, CBD seems to fight the roots of the problem instead of just masking the symptoms. Cannabidiol acts as a 5-HT1A agonist. 5-HT1A is an important serotonin receptor helping brain cells transmit more serotonin signals. This, in turn, results in reduced anxiety and improved mood. The therapeutic effects of CBD were proven in animal-model studies.
One of the best CBD oil for anxiety review proved that this oil is more than just beneficial when it comes to the quality and the energy levels people experienced. In general, people who took the oil noticed a much better improvement in the sleep quality. As such, they were able to sleep better and longer every night. What this means is that you will have more energy to fight these two conditions and you will decrease the intensity of the symptoms.
Once again, there is no side effect on the overall health and all of this is more than just safe to know and to use.

Also, you will be able to defend yourself much better than other people from the same issues and you will be able to win the battle. BTW, check our best cbd oil for pain.

The nutrition and supplement industry—which includes CBD products—is almost wholly unregulated. “The concentrations in products are only approximate, and I don’t know how well they’re tracked,” Szaflarski says. Even if you could absolutely trust a product’s label—and many CBD manufacturers, aware of the current scrutiny on their industry, go to great lengths to assure consumers of the quality of their products—there aren’t a lot of concrete facts when it comes to the type or amount of CBD a person should take for a specific ailment or aim.

People suffering from other neurological disorders might also benefit from using CBD oil as part of their treatment. Several studies involving Parkinson’s disease showed that participants slept better after treatment. Furthermore, their overall quality of life increased. Amazingly, CBD also showed positive benefits in treating or preventing Alzheimer’s disease. As CBD lowers inflammation, it helps prevent nerves from degenerating. During one study, scientists used mice with the genetic predisposition for Alzheimer’s disease. They found that CBD helped by preventing the mice’s cognitive decline.

Because CBD oil products are mostly unregulated, there’s no guarantee that any given product contains a safe or effective level of CBD. In fact, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are incorrectly labeled, and could cause serious harm to consumers. Some CBD oils may also contain incorrectly labeled amounts of THC and other compounds.
