"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.
I am 70 years old and have arthritic pain and stiffness in my hands. I work part-time for a delivery company and spend 4-5 hour shifts removing small and large packages from a belt think of Lucy and Ethel at the chocolate factory. I bought the 3000 MG tincture about two weeks. I started out with 6 drops @ 2X per day 30MG. It took the edge off of aches and pains from working and arthritic pain but increased the dose to 7 drops @ 3 times per day 52.5 MG. Although I still felt some aches and pains it decreased considerably. Today I have started 7 drops 4X per day 75 MG. I anticipate getting much better results. All-in-all I am quite pleased with the 3000 tincture oil. I feel that the oil has given me more energy to do things around the house probably because I am now experiencing much fewer aches and pains in my body and hands. By the way the reason I am taking the oil 4 times a day is because I read that the body will not absorb more than 15 MG at a time and discards any oil above that amount. It may not be true but thats my story and Im sticking to it.
CBD also modulates other receptors in the body. For instance, modulation of the 5-HT1A receptor (involved with serotonin, a mood hormone) provides mood-balancing properties: It’s calming, but not highly sedating, so it’s considered neutral — though it often results in improved sleep for many people. Another example is modulation of opioid receptors, which provides pain relief and tissue-supporting properties.
The nervous system’s endocannabinoid system is not well understood. But it’s thought to play a role in regulating pain, sleep, mood, memory, appetite, and other cognitive and physical processes. Because CBD is able to mimic the actions of some natural brain chemicals, its potential therapeutic benefits are wide-ranging but—at this point—nebulous. “We know that cannabidiol modulates the endocannabinoid system, but we don’t know how it works,” Szaflarski says. That said, there are theories.
Chronic pain can be nociceptive or neuropathic. Nociceptive pain is the most common and is caused by tissue damage and inflammation. It’s characterized by throbbing, aching, and sharp pain. Neuropathic pain is caused by damage to the nervous system and can feel like stabbing, burning, or tingling pain. Studies on cannabinoids and pain demonstrate that CBD can treat both types of pain.
This non-greasy formula is a lightweight counterpart to all those heavy hemp salves and balms that you tend to see on the market, so much so that you could use this every day on your entire body without worries about staining your clothes. Along with the Colorado-grown CBD oil, it has a lotion base made with aloe vera leaf juice powder (good for antioxidants), lactic acid (good for exfoliation), and other reputable skincare ingredients. Keep this by your shower and use it while your skin is still moist, warm, and soft for the best results.

Children:A prescription cannabidiol product (Epidiolex) is POSSIBLY SAFE when taken by mouth daily. The most common dose used is 10 mg/kg daily. Higher doses of 15-20 mg/kg daily may be used in some children, but these higher doses are more likely to cause side effects. This product is approved for use in certain children 2 year of age and older, but has been used in children as young as 1 year of age.


Why support the endocannabinoid system? The endocannabinoid system (ECS) is gaining attention in the public eye for its role in contributing to an individual’s overall health and well-being by supporting the body’s physiological homeostasis. The ECS regulates nearly every metabolic process in the body system. A well-balanced ECS encourages favorable conditions in the body system, impacting the body’s ability to manage metabolic stress1 and may support overall health and well-being.2
To use CBD for pain you will find that the application process is quite easy. If you are having pain that is in your skin, muscles, or nerves that are near the skin level, you can simply rub a few CBD drops into your skin and you will feel the effects of pain relief almost instantaneously. It doesn’t take a whole lot of effort for this to have the positive effects you are looking for.

I am new to taking CBD and was initially very hesitant to do so. Growing up in the drugs will fry your brain era, it was very difficult to change that mind set, as CBD was lumped into anything cannabis related. I saw this article (https://cbdeducationonline.com/what-is-cbd/) and learned more about CBD, but wasn’t sure entirely what it could be used for. Thanks to your article I have a more well rounded understanding and my son is going to get me some for my arthritis pain. I have had it for year and it runs in my family…. Thanks for your article

REM behavior disorder: REM behavior disorder (RBD) is a parasomnia disorder characterized by shouting, becoming physically agitated, or otherwise acting out during sleep. For many, RBD is a symptom of a larger, more serious condition or disorder, such as Alzheimer’s disease or PTSD. CBD oil minimizes the symptoms of RBD, and also alleviates the anxiety and painful symptoms that often accompany disorders that lead to RBD.


CBD is a safe, long-term aid which is why it has gained such momentum and why our customers are turning to it for relief. CBD, scientifically known as cannabidiol, is a non-psychoactive, natural compound found in the hemp plant. When it interacts with the body’s endocannabinoid system, CBD provides powerful health benefits without the side effects of conventional drugs. The CBD utilized in our tinctures is extracted from industrial hemp cultivated in the United States. To further ensure quality and purity, our industrial hemp goes through a supercritical CO2 extraction process to obtain the best possible CBD solution. This solution is then formulated by our board-certified pharmacists into finished products and sent out for third-party testing. Our CBD oil is made with high-quality CBD extracted from natural hemp that is abundant in naturally produced terpenes, oils, vitamins, omega fatty acids, and other components.
This oil is derived from the Cannabis sativa plant that can contain both CBD and THC in varying concentrations. The clear drawback of cannabis oil is that it cannot be purchased outside of a state that has not legalized the sale of cannabis. Cannabis oil can also contain higher amounts of THC, which could be problematic for those not looking for the psychoactive effects of cannabis oil.

The 2014 Farm Bill[74] legalized the sale of "non-viable hemp material" grown within states participating in the Hemp Pilot Program.[75] This legislation defined hemp as cannabis containing less than 0.3% of THC delta-9, grown within the regulatory framework of the Hemp Pilot Program.[76] The 2018 Farm Bill allowed for interstate commerce of hemp derived products, though these products still fall under the purview of the FDA.[77][78]


Results of a Phase III study (N = 177) comparing Sativex, THC-predominant extract and placebo in intractable pain due to cancer unresponsive to opiates (Johnson and Potts 2005) demonstrated that Sativex produced highly statistically significant improvements in analgesia (Table 1), while the THC-predominant extract failed to produce statistical demarcation from placebo, suggesting the presence of CBD in the Sativex preparation was crucial to attain significant pain relief.

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.


When used as treatment for pain, CBD has a powerful effect on neuropathic pain, which is pain of the nerves and might be caused by peripheral nerve injury or other factors. By activating CB2 receptors, CBD activates many of the pathways that ease pain, and this goes a long way towards managing long term conditions such as diabetes, MS, and fibromyalgia.
If you're confused by the sudden ubiquity of CBD and cannabis-based products, you're not the only one. "My state doesn't even allow medical marijuana," Idahoans or South Dakotans may say. "So why can I suddenly walk into my local Sephora and buy cannabis oil mascara?" As you can imagine, it's complicated. And claims that CBD is 100% legal in all 50 states (which appear frequently) are oversimplifying the matter.

Currently, the U.S. National Library of Medicine lists just 25 clinical studies involving CBD and its effects on pain. Only a handful of those have been completed so far, but there are more in the works. Many of these trials involve pain in people with advanced cancer, and while some show positive pay-offs, others demonstrate that cannabis treatment doesn’t provide any more relief than a placebo. The catch: Most of this science involves both CBD and THC (or Δ9-tetrahydrocannabinol, the part of cannabis that does give you a high).
Chronic pain is a major issue in the health sector and millions of people rely on pain medication to go about their normal lives, but synthetic painkillers are known for causing side effects that make them unsafe for long-term use. Alternative pain treatments like hemp oil have shown a lot of promise for people with injury-related pain, arthritis, and other types of chronic pain.

The 2014 Farm Bill[74] legalized the sale of "non-viable hemp material" grown within states participating in the Hemp Pilot Program.[75] This legislation defined hemp as cannabis containing less than 0.3% of THC delta-9, grown within the regulatory framework of the Hemp Pilot Program.[76] The 2018 Farm Bill allowed for interstate commerce of hemp derived products, though these products still fall under the purview of the FDA.[77][78]
While in all of these states recreational marijuana remains illegal, Connecticut, Delaware, Illinois, Maryland, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New York, North Carolina, Ohio and Rhode Island have all decriminalized the drug. In these states, having smaller amounts of marijuana on you won't lead to an arrest or a criminal record. The maximum amount you're allowed to have on your person will vary by state.
I’ve been hoarding Girl Scouts Thin Mints lately (they’re especially good if you freeze them)—the chocolate is fine, but the peppermint oil is what makes them addicting enough to go through a whole sleeve without getting sick of them. I’m also trying to cut down on sugar, though, and while it would be a huge stretch to say that this peppermint oil-infused clear lip balm is a direct replacement for Girl Scout cookies, it really does have a very satisfying full-mouth taste of peppermint. The CBD oil, which soothes and facilitates healing at the same time, makes this formula an ideal balm for outdoor enthusiasts and or just those who are prone to painfully chapped lips. For those of us with long-hair-don’t-care, it’s not sticky—as a matter of fact, the formula is on the stiff side and won’t cause your hair to stick to your face, a welcome departure from many balms.
Chronic pain is a major issue in the health sector and millions of people rely on pain medication to go about their normal lives, but synthetic painkillers are known for causing side effects that make them unsafe for long-term use.

Yes! when cold turkey no choice pulled off opiates when cancer returned I turned to medical marijuana! Yes I call it what it is because it saved my life in many ways, believe me I never thought could smoke it because anxiety/paranoid but it’s not true! It’s about educating yourself on the strains and different plants! No one plant is made the same. I highly recommend the Indica now it is known to be best for night because it does put you out as well as that pain! I have cut my Xanax in half! Indica is the one that will make you more relaxed and sleepy but talk about pain relief! also helping with sleep and anxiety! Sativa is your uplifting the happy type more to the head type plant, it will deliver some pain relief depending on which Sativa plant – it will deliver but this strain is known for weight loss, helps with depression, however it can on some plants trigger the anxiety people talk about – you would need to get the plant name and look up medical benefits then side effects, there is sites on this. I studied this plant very thorough before I ever began it. I choose the whole plant with THC – I hate it gets demonized, the THC has around 15 medical benefits. It gets demonized because like a opiate you can get mind altered – well the way I see it .. why is it so sinister to feel good when I live in hell of cancer pain. THC is a killer anti inflammatory! It is 1,000 more strong than aspirin and 100 times more strong than hydrocodone as far as anti inflammatory!!! which is essential for cancer and pain as well. Even an FDA-approved trial in 2013 confirmed THC’s effectiveness for pain relief. Individuals experiencing neuropathic pain were given low doses of THC (1.29%) in the form of vaporized cannabis. The results? “A low dose of delta-9-tetrahydrocannabinol provided statistically significant 30% reductions in pain intensity when compared to placebo.”While clinical research continues to be restricted due to cannabis’s regretful status as a !I controlled!!!
This isolate spectrum CBD has helped turn my life upside down I have been dealing with negativity and social anxiety since I was 13. Now that Ive used this product along with daily meditation my life has been positive and the anxiety is no longer there I would never have motivation to leave the house to get things done before. Now I always feel the need to get up and get what I need done I never take the time to review any products. I love this product Give it a shot. I recommend 1000mg for your first time. Its perfect
California’s legalization spurred Dr. Geoffrey Guy and Dr. Brian Whittle to found GW Pharmaceuticals, a company that would utilize clinical trials to unpack various cannabinoid formulations as potential therapies with the overriding focus of developing what would later be known as Sativex (Nabiximols). This oral mucosal spray was made up of CBD and THC in a 1:1 ratio and successfully combated neuropathic pain, spasticity, overactive bladder, and symptoms of multiple sclerosis.

In order to remove unwanted elements such as fats or waxes, CBD oil is subjected to a process called ‘Winterization’. Refined cannabidiol oil is stirred with alcohol and deep-frozen overnight.  A Butcher funnel or a piece of paper is then used to filter the fats out. Finally, the extracted oil is heated to the boiling point of alcohol so the alcohol evaporates.

CBD oils that are produced from industrial hemp and not marijuana, are recognized as legal no matter what state you are in within the United States. Marijuana derived products are a bit more of a legal grey area but are permitted throughout many of the 50 states. Most vendors of CBD oil offer doorstep delivery, making it convenient and easy to receive your CBD purchases.
Hemp seed oil made from the industrial hemp plant contains only tiny trace amounts of THC. THC is why marijuana is illegal in so many countries and states. So, since industrial hemp oil is low in THC but contains high amounts of CBD, you can get your CBD hemp oil legally in all 50 states and shipped right to your home. You won’t get a high from CBD oil, but you will get all the health benefits of a high-quality CBD supplement.
Until 2017, products containing cannabidiol marketed for medical purposes were classed as medicines by the UK regulatory body, the Medicines and Healthcare products Regulatory Agency (MHRA) and could not be marketed without regulatory approval for the medical claims.[89] As of 2018, cannabis oil is legal to possess, buy, and sell in the UK, providing the product does not contain more than 0.2% THC and is not advertised as providing a medicinal benefit.[90]

A neuron’s sensitivity to a specific neurotransmitter depends on whether or not it contains a receptor that “fits” that transmitter, like an electrical socket fits a plug. If a neuron contains receptors that match a particular neurotransmitter, then it can respond directly to that transmitter. Otherwise, it generally can’t. All neurons contain multiple neurotransmitter receptors, allowing them to respond to some neurotransmitters but not others.

If your intention is to help treat chronic pain, then you may want to start out with a lower dose, and then proceed from there. If you notice effective results, you can downsize the dose, or likewise you can always up the dose until positive results are achieved. The key is to only increase your dosage in small increments so that you are able to pinpoint exactly how much CBD oil it takes to treat your condition. Be advised, though, that you should not exceed the recommended daily doses that are listed on the bottle and you should consult with a physician.


In a SAFEX study of Phase III double-blind RCT in 160 subjects with various symptoms of MS (Wade et al 2004), 137 patients elected to continue on Sativex after the initial study (Wade et al 2006). Rapid declines were noted in the first twelve weeks in pain VAS (N = 47) with slower sustained improvements for more than one year. During that time, there was no escalation of dose indicating an absence of tolerance to the preparation. Similarly, no withdrawal effects were noted in a subset of patients who voluntarily stopped the medicine abruptly. Upon resumption, benefits resumed at the prior established dosages.
It should be noted that recreational use of marijuana (high THC, low CBD cannabis) does result in dependence (but different from narcotics or alcohol, and not as debilitating). Chronic use of THC may be associated with atrophy in certain areas of the brain and reduction of certain cognitive functions (at this point, studies are not conclusive). Interestingly, studies have shown that taking CBD oil regularly can restore areas of the brain that have become atrophied in marijuana abusers.

Pros: This item is organic and produced in the USA. The appearance of the oil is very much like extra virgin olive oil, as it should be. It has a green shade indicating that it is full spectrum and unrefined. Nature’s Blueprint also added natural peppermint to make it more palatable. I think it tastes fine straight from the dropper, but it can also be added to a smoothie of some sort or maybe hot tea? I appreciate that it has a clear label for the supplement facts and dosing. If you ever buy something that doesn’t, I certainly wouldn’t take it.


Adverse effects of cannabinoids on immune function have been observed in experimental animals at doses 50–100 times the psychoactive level (Cabral 2001). In four patients using herbal cannabis therapeutically for over 20 years, no abnormalities were observed in leukocyte, CD4 or CD8 cell counts (Russo et al 2002). Investigation of MS patients on Cannador revealed no major immune changes (Katona et al 2005), and similarly, none occurred with smoked cannabis in a short-term study of HIV patients (Abrams et al 2003). Hematological measures have been normal in all Sativex RCTs without clinical signs of immune dysfunction.

If you live with chronic pain, you may have experienced how it can disrupt sleep and, in some cases, can contribute to anxiety and depression. Natural therapies, including exercising and taking up mind-body practices like meditation and yoga, and following an anti-inflammatory diet may help improve quality of life for some people who experience pain regularly.
Insomnia: The anxiety-alleviating and sleep-prolonging qualities of CBD oil make it a good option for many people with insomnia. Those who experience insomnia due to pain or discomfort may also find that using CBD oil alleviates their physical symptoms to a noticeable extent. CBD oil may also promote daytime wakefulness when taken in small amounts; people with insomnia can use it as a pick-me-up if they feel excessively tired due to lack of restful sleep.
The degree to which a drug is reinforcing is determined partly by the by the rate of its delivery to the brain (Samaha and Robinson 2005). Sativex has effect onset in 15–40 minutes, peaking in a few hours, quite a bit slower than drugs of high abuse potential. It has been claimed that inclusion of CBD diminishes psychoactive effects of THC, and may lower potential drug abuse liability of the preparation (see Russo (2006b)) for discussion). Prior studies from Sativex clinical trials do not support the presence reinforcement or euphoria as problems in administration (Wade et al 2006).
The trace amount of THC in CBD oil (<0.3%) is not enough to trigger most drug tests as being positive for THC. You would need to consume about 1000-2000 mg per day of CBD to fail a drug test for THC if the employer is testing to SAMHSA guidelines (Substance Abuse and Mental Health Services Administration). If you are tested regularly and taking high doses of CBD, and you are concerned about the very low risk of a positive drug test for THC associated with using hemp-derived products, you could opt to use purified CBD, which does not contain anything but CBD. Just know that purified CBD doesn’t provide the same spectrum of benefits as CBD oil.
I have been using the 1000mg tincture and find that it is very effective at taming anxiety once I found the dosage that worked for me. I started small at 1 drop 3x per day because I had never used CBD before and found that 4 drops 3x a day is currently appropriate to get the results I am looking for. I am glad I found Medterra. Before making a CBS purchase, I did tons of research and felt that they were one of the best in the market. Customer Service response time was same day when I sent them a question.

Ringo’s Gift: This cultivar is named after the cannabidiol pioneer, Lawrence Ringo. Ringo’s Gift is a cross between two other CBD-rich strains, AC/DC and Harle-tsu. Its CBD to THC ratio varies from 1:1 to 22:1, but it consistently favors CBD. Ringo’s Gift smells of earthy pine and promises full-bodied relaxation in tandem with calming cerebral effects which, together, silence pain and anxiety.
Cannabis has been around for thousands of years and is believed to have originated in South or Central Asia. The two main species of cannabis are Cannabis sativa and Cannabis indica. Both Cannabis sativa and indica contain varying amounts of psychoactive and nonpsychoactive components. Cannabis sativa is more commonly known for its stimulatory, mental effects while Cannabis indica is more known for its relaxing, body-calming effects.

Adding CBD honey to calming tea, or putting a few drops under the tongue doesn’t carry the emotional baggage of taking pills. Pills scream, “you’re sick!” Healing treatments that fall outside the “pill” association are all the more powerful. They help you separate yourself from the “sick” person. Furthermore, CBD oil benefits go beyond treating chronic pain.


Very few randomized controlled trials (RCTs) have been conducted using smoked cannabis (Campbell et al 2001) despite many anecdotal claims (Grinspoon and Bakalar 1997). One such study documented slight weight gain in HIV/AIDS subjects with no significant immunological sequelae (Abrams et al 2003). A recent brief trial of smoked cannabis (3.56% THC cigarettes 3 times daily) in HIV-associated neuropathy showed positive results on daily pain, hyperalgesia and 30% pain reduction (vs 15% in placebo) in 50 subjects over a treatment course of only 5 days (Abrams et al 2007) (Table 1). This short clinical trial also demonstrated prominent adverse events associated with intoxication. In Canada, 21 subjects with chronic pain sequentially smoked single inhalations of 25 mg of cannabis (0, 2.5, 6.0, 9.5% THC) via a pipe three times a day for 5 days to assess effects on pain (Ware et al 2007) with results the authors termed “modest”: no changes were observed in acute neuropathic pain scores, and a very low number of subjects noted 30% pain relief at the end of the study (Table 1). Even after political and legal considerations, it remains extremely unlikely that crude cannabis could ever be approved by the FDA as a prescription medicine as outlined in the FDA Botanical Guidance document (Food and Drug Administration 2004; Russo 2006b), due to a lack of rigorous standardization of the drug, an absence of Phase III clinical trials, and pulmonary sequelae (bronchial irritation and cough) associated with smoking (Tashkin 2005). Although cannabis vaporizers reduce potentially carcinogenic polyaromatic hydrocarbons, they have not been totally eliminated by this technology (Gieringer et al 2004; Hazekamp et al 2006).
