The National Cancer Institute details several studies into the anti-tumor effects of CBD. One study in mice and rats suggest CBDs “may have a protective effect against the development of certain types of tumors.” CBDs may do this by inducing tumor cell death, inhibiting cancer cell growth, and by controlling and inhibiting the spread of cancer cells.
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.

A crop for the future? With modern farming in big trouble, farmers are being paid not to cultivate their land, and food mountains are burnt in developed countries, while billions of people go hungry in developing countries. Hemp represents a lifeline crop for rural and hunger-prone areas, of particular value for its' versatility and organic nature. A famine-stricken village could clothe, house and feed themselves from one hemp field!
The reason for the low THC content in hemp is that most THC is formed in resin glands on the buds and flowers of the female cannabis plant. Industrial hemp is not cultivated to produce buds, and therefore lacks the primary component that forms the marijuana high. Furthermore, industrial hemp has higher concentrations of a chemical called Cannabidiol (CBD) that has a negative effect on THC and lessens its psychoactive effects when smoked in conjunction. 
I have fibromylagia and was on a cocktail of 20 medicines. Last year I quit them all cold turkey one day. Was tired of the rate race, doctors visits, refills, cost, etc. I live in pain on a scale of 9 out of 10 most days and then had a car accident , was hit from behind and ended up with 3 herniated disks. I eat Ibuprofen like it’s candy some days and that has to stop. I ordered my first CBD oil today and am hoping it helps me. My son is a Vet and has been using these products for years and swears by them for his PTSD and war injuries.
I purchased Ananda professional full spectrum Extract 600 20/mg/ml CBD oil. I started with .5ml dose the first night right before bedtime. I did not sleep well. I tried the same dose the following evening, and again, poor sleep. I tried it for two more nights and had the same results. I’m very sensitive to steroids and will only use them as a last resort, but the way I felt after taking the CBD oil, reminded me of how poor my sleep is on steroids. Or how vitamin B12 can affect me if I take it too late in the day. I have a lot of inflammation and pain and hoped the CBD oil would help. I am quite surprised at my reaction to it. Anyone else have trouble sleeping when taking it?
Many people are familiar with cannabidiol (CBD), which is found in highly concentrated amounts in our products, but there are actually dozens of cannabinoids found in hemp, which have shown many benefits in studies. We choose to make all our products with full-spectrum hemp oil, which includes all of the cannabinoids found in the plant, so you don’t miss out on any of the benefits.

A fluctuation of electrical activity in the brain is the main trigger of seizures. While there were unconcluded studies that CBD can control seizures it was not until recently that scientists confirmed the claims. Placebo research involving double-blind patients conducted by The New England Journal of Medicine showed that CBD medication administered in people diagnosed with the Dravet syndrome could help reduce the symptoms.
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”

Regarding your comment on CBD and colitis or inflammatory bowel disease. Immune cells patrol the gut to ensure that harmful microbes hidden in the food we eat do not sneak into the body. Cells that are capable of triggering inflammation are balanced by cells that promote tolerance, protecting the body without damaging sensitive tissues. When the balance tilts too far toward inflammation, inflammatory bowel disease can result. Now, researchers have found that a kind of tolerance-promoting immune cell appears that carry a specific bacterium in guts called Lactobacillus reuteri that is the normal part of the gut microbiome, and tryptophan, part of a protein-rich diet, soothes the inflamed gut because it increases the development of a population of immune cells that promote tolerance. Further, the bacterium needs tryptophan — one of the building blocks of proteins — to trigger the cells’ appearance, and the more tryptophan in the diet to feed the gut bacterium, Lactobacillus reuteri, the more of these immune cells there are.
A healthy appetite is vital to a healthy body, especially when the body is healing. Some illnesses decrease the appetite to the point of preventing the body from healing itself. CBD stimulates appetite, according to the National Cancer Institute. In the human body, CBDs bind to cannabinoid receptors in the body. Scientists believe these receptors play an important role in regulating feeding behavior. CBDs stimulate appetite when they dock onto these receptors.
Lazarus Naturals products have received a rapturous reception from users due to their ability to give results. Their tinctures are easy to administer and can clear headaches in as fast as 30 minutes. Their CBD oil will provide a calming bodily sensation in about the same time. The effects can last for up to five hours. Other than that, the isolates come in a variety of flavors ranging from Valencia orange to Raw, Lemon Lime, and Citrus.
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.

I always quote CBD oil as a “miracle cure”. The reason being when no other regular meds helped me there was CBD oil that helped me with my chronic back pain. Been using it for the past 2 years now. I haven’t tried the Kope CBD products but after reading this I’m curious. Rest all brands are well known to me. Let’s give Kope a try. Anyways, thanks for sharing this awesome information.
As I research more I am disgusted with how we have all been deceived. I feel confident now with being able to research things on our own, at any moment in time, we can begin to take back our world. In the early 30’s one of the great media conspiracies unfolded. Publisher William Hearst, Dupont, the petroleum interests, the cotton lobby, the bankers and some ignorant politicians lead a crusade to ban hemp to line their pockets. Hemp can revolutionize our society. Please research and pass on!
I’m glad so many of you have been helped; I tried it upon recommendation from accupuncturist to help with anxiety & funny mood in the afternoon. The first night I woke up in the middle of the night and couldn’t get back to sleep, and had the most horrible constant headache for the 3 days after I took it (and I hadn’t had a headache in months). Also had the anxiety/funny mood all day long. And burning eyes.
The Medterra tincture utilizes an extraction process that effectively separates plant material while filtering unnatural substances, optimizing the CBD concentration. It has also undergone third-party testing to ensure quality and consistency. Just so you may know, this oil is odorless and tasteless, allowing you to take using various ways including adding it to your food or dropping it under your tongue.
CBD oil herbal drops are hitting the healthcare industry by storm, gaining in popularity daily due to number of people using CBD as an alternative to many commercial products. Many studies are demonstrating how this oil is naturally assisting in the healing process of many health conditions. This oil can be used orally or topically depending on the benefits you are seeking. To consume, just put a few drops to a full dropper on or under your tongue.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.

“The political implications of that scheduling, from a research perspective, are limiting,” explains Sutton. “To my knowledge, of the thousands of academic and research bodies in the United States and Canada whom would be equipped to perform agricultural or medical research on this unique species, only around 40 have actual research licenses to study the plant in a limited context.”


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.
CBD derived from marijuana is a different story, and the law varies from state to state. But as long as you’re using CBD oil that contains less than 0.3 percent THC, you have nothing to be concerned about anywhere in the United States. On the other hand, if you want to take your CBD on a trip outside the country, definitely look into local laws to avoid getting into awkward situations while you’re away.
For this ranking update, we also looked at whether companies are providing third-party lab tests for their products post-formulation or if they’re just testing the source isolate or CBD extract which goes into all their products. Nobody can test every single bottle of product, but samples of each product can be tested for cannabinoid potency at a minimum.
Hemp oil (also called hemp seed oil) is extracted from the hemp seeds of the hemp plant and it contains very little or no THC. Cannabis, on the other hand, has THC levels above 0.3 percent (usually between 5-35 percent). Because of its low THC levels, you can use hemp oil without feeling “high” afterwards. Hemp is typically grown for industrial purposes, as it’s used to make clothing, paper, ropes, carpets, construction materials and plastic composites.

However, if it was sourced from actual marijuana (i.e. cannabis that contains more than 2% THC by volume), then it is technically illegal. Most of the best CBD oils for pain that you find in dispensaries in states like Colorado, California, and Washington (as well as other states where weed is legal) will have been extracted from marijuana plants — not industrial hemp plants. Unfortunately, this means that these products are not allowed to be sold online and shipped across state lines to “non-legal” states.
You don’t always want to believe the experts, trust me on this. In fact I’ve had certain issues often on over the years were natural alternatives were the key to natural healing. In fact, when dealing with a fracture many years ago, if you recall it took about six weeks to heal. Mine healed in four or less. Now getting back to the hemp oil, It actually helps with arthritis pain in my case. I’ve also noticed if I up my magnesium levels I have lesser of a chance of having a myoclonic seizure. If you really do your homework, you’ll find out but nutritional deficiencies cause a whole host of problems if not most of them. If we weren’t meant to have the plant, it wouldn’t be here as it serves a purpose

My Wife had Polio at age 5 and the lingering damage to the L leg and muscle drove her crazy. At age 21 she was using heavy doses of muscle relaxers and pain meds. Needed to bomb herself at night to get some sleep. A Post polio group in West Palm Beach told her about Marijuana and she got some from the Jamaican health aide that was her constant helper. After 5 months she quit all meds. All of them. Slowly came out of the drugged state the meds had caused from 15 years of use. We separated good friends and I know she has gone back to school and getting a degree. All from the help of a plant from Jamaica. I never understood the statement this plant has no viable medical value. Something smells in the politics of this prohibition. Shame.
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.
CBD oil also helps with rheumatoid arthritis. A separate study involving 58 participants showed that they all experienced improvements. Most of their resting and movement pain was lowered. Furthermore, their quality of sleep also improved.CBD is a natural alternative to the common prescription drug people use to relieve pain and stiffness. Also, research shows that CBD can reduce chronic inflammation and pain, as well.

Luginbuhl, April M. (2001). "Industrial hemp (Cannabis sativa L): The geography of a controversial plant" (PDF). The California Geographer. 41. California Geographical Society. pp. 1–14. hdl:10211.2/2738. Retrieved 28 March 2013. Hemp contains less than 1% THC, or tetrahydrocannabinols, the psychoactive property in marijuana. In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated. (Roulac 1997; 149).
The most abundant cannabinoid in hemp oil, making up over 90% of the cannabinoid content, cannabidiol or CBD is non-psychoactive and is the focus of the benefits from hemp oil. CBD has little affinity for CB1 or CB2 receptors, the main points of interaction for cannabinoids in the endocannabinoid system, and instead acts as an indirect antagonist of cannabinoid agonists, possibly allowing CBD to temper the high caused by THC. Our Gold Label RSHO™ is almost 25% CBD, making up most of oil’s weight. All other cannabinoids come in under 0.4% by weight.

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.CBD can have beneficial effects on people who suffer neurological disorders such as epilepsy and multiple sclerosis. Amazingly, CBD showed positive benefits in treating or preventing Alzheimer’s disease. As CBD lowers inflammation, it helps prevent nerves from degenerating.

There are eight dimensions of wellness: occupational, emotional, spiritual, environmental, financial, physical, social, and intellectual. Each dimension of wellness is interrelated with another. Each dimension is equally vital in the pursuit of optimum health. One can reach an optimal level of wellness by understanding how to maintain and optimize each of the dimensions of wellness.

And in the medical world, we've really just barely begun to scratch the surface of the many potential uses of CBD as an alternative, plant-based form of medicine. From the FDA approving a revolutionary CBD-based drug used to treat epilepsy, to studies proving that cannabis has helped patients with glaucoma and those suffering from inflammation, one point is becoming increasingly clear: CBD can help people with all sorts of ailments.


Another common use of CBD is relieving pain. Following research, discovery has been made on the components present in cannabis that makes it an active pain-relieving substance. The endocannabinoid system (ECS) in the body is responsible for functions that involve regulating pain. Since CBD impacts the pain receptor activity in ECS, it can relieve an individual from even chronic pain. Combining CBD and THC is an effective means of treating pain related to sclerosis and arthritis.

The first thing that comes to mind when we think of CBD products are the smokables such as vape products. CBD vape oil and CBD oil vape juice are very popular among patients because their effects are almost instantaneous. What’s more, they are ideal for a wide variety of issues – from pain to panic attacks. To consume them, you need a CBD vape pen and smokeable products like e-liquids.
CBD oil can treat physiological problems. Repeated research shows that’s the oil makes a brilliant addition to a mental health treatment regimen for conditions such as anxiety. A study carried out the University of Sao Paulo suggests that CBD lowers subjective anxiety considerately by affecting the activity in paralimbic and limbic areas of the brain.

Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age."[111] "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."[112]
So what exactly is Industrial Hemp? For most people, the first thought which comes to mind when someone mentions “industrial hemp” to them is – marijuana. But, industrial hemp is very different from marijuana, specifically in terms of the potential to get someone “high”, as it contains very small amounts of delta-9 tetrahydrocannabinol (THC – the psychoactive chemical).
Although it may be better to consume CBD alone than nothing at all, it may not offer you the same range of positive effects as full spectrum CBD oil. With full spectrum CBD, not only will you get adequate CBD, but you’ll also consume dozens of beneficial cannabinoids and terpenes. As a result, your body will receive more than enough vitamins, minerals, and nutrients.

Other than being Medterra’s most sought-after product, this tincture contains over 99% CBD and MCT. In essence, this translates to excellent efficacy. With such composition, it is a perfect pick if you’re in for CBD oil for anxiety. Plus, this tincture is legal, easy to use and pocket-friendly. The Medterra CBD tincture comes in 500mg. 1000mg and 3000mg in 30 servings usable day and night.
Since our beginning, Medical Marijuana, Inc. has been striving to bring the health benefits of cannabinoids to the lives of as many people as possible through cannabinoid hemp oil supplements. With our knowledge of cannabinoids and the endocannabinoid system just scratching the surface of what’s possible, there is plenty of potential to find new uses for the myriad of cannabinoids available to us.

The color of CBD oil drops can range from clear or slightly golden, to a dark brown almost black. Color of the finished product is determined by several factors, including the type of CBD extract, the extraction method used, the carrier oil used and additional ingredients. Full spectrum (whole plant) extracts tend to be darker in color whereas isolates tend to be more clear.
Sativex, an oral spray containing both CBD and THC, can treat MS-induced pain. During one study, researchers gave Sativex to 47 participants with MS. Results were largely positive. Patients who used this spray felt notably better. Their muscle and walking spasms decreased, and they felt pain relief. Thanks to studies such as this one, several countries approved using Sativex in MS treatment.

Queensland has allowed industrial production under licence since 2002,[78] where the issuance is controlled under the Drugs Misuse Act 1986.[79] New South Wales now issues licences[80] under a law, the Hemp Industry Regulations Act 2008 (No 58), that came into effect as of 6 November 2008.[81] Most recently, South Australia legalized industrial hemp under South Australia’s Industrial Hemp Act 2017, which commenced on 12 November 2017.[82]
While cannabidiol (CBD) is all the rage at present, it is often hard to understand what you are getting. Furthermore, with so many different CBD products on the market, it’s hard to tell which are full spectrum, which are not and which products are made from CBD cannabis or CBD hemp.  In this article we will try to clear up any confusion, focusing the major part of the post around Full Spectrum CBD oil.

“This is my first cbd oil I tried. Within a few minutes, I can feel my body started relax. It felt like every single cell of my body relaxed before my mind. I got this for anxiety, and relaxation of mind came later. I don’t recommend taking it before driving because it made me so sleepy. I can now sleep through the night without waking up. I didn’t realize how tense my body was until I started taking this. I am calm and don’t feel much anxiety any more. I love it!“
Multiple studies showed that CBD has properties that reduce inflammation. As such, it can be used to decrease sebum production. In other words, CBD oil might be good for your acne problem. One test-tube study showed that CBD had a noticeable effect on the sebaceous cells. When they came into contact with CBD oil, these cells stopped secreting any excess sebum. On top of that, CBD also lowered inflammation and stopped the so-called inflammatory cytokinesis before it manifested.
Hemp’s potential widespread adoption as food for humans is also very promising. Hemp seed has high levels of protein, carbohydrates, fiber, vitamins, essential fatty acids and trace elements.  Oil from hempseed, which can comprise nearly a third of the seed’s weight, makes it an ideal source for cooking oil, lighting and biofuels.  Hempseed oil is also valuable as a component of personal care products such as soaps, conditioners and lotions.

 The difference is in its use. Hemp and Marijuana both come from the same plant - Cannabis Sativa L. The term 'Hemp' commonly refers to the industrial/commercial use of the cannabis stalk and seed for textiles, foods, papers, body care products, detergents, plastics and building materials. The term 'marijuana' refers to the medicinal, recreational or spiritual use involving the smoking of cannabis flowers. Industrial hemp contains only about 0.3% - 1.5% THC (Tetrahydrocannabinoids, the intoxicating ingredients that make you high) while marijuana contains about 5% - 10% or more THC. Hemp fibre is the longest, strongest and most durable of all natural fibres. Hemp cultivation requires no chemicals, pesticides or herbicides. Grown in rotation with other crops such as corn and legumes, hemp farming is completely sustainable. Hemp produces four times as much fibre per acre as pine trees. Hemp tree-free paper can be recycled up to seven times, compared with three times for pine-pulp based papers. Hemp is easy to grow, and actually conditions soil where it grows. The seed and seed-oil are high in protein, essential fatty and amino acids, and vitamins. Hemp would be an ideal source of biomass for fuel, and hemp Ethanol burns very cleanly.

Cannabinoids assist in the bone cycle of a human body – the process which allows old bone material to be replaced by new materials. When CBD is consumed, it hinders the activity of an enzyme responsible for destroying bone-building parts of the body. This action of CBD helps in reducing associated bone problems (aka bone diseases that are usually prevalent during old age. In cases where damage has been done to the bone, CBD facilitates the process of bone cell formation, speeding up the healing of broken bones and other bone problems.
