While everyone has their own unique body chemistry, it seems like the vast majority of people can ingest CBD oil without ever feeling any unpleasant side effects at all, and the remaining few will mostly likely experience only minor symptoms like stomach upset or dry mouth. Since scientists are using pure extracts from known sources, it’s likely that some consumer reports of headaches or other minor adverse reactions could be due to impurities in inferior CBD products.

For epilepsy: A prescription cannabidiol product (Epidiolex) has been used. The recommended starting dose is usually 2.5 mg/kg twice daily (5 mg/kg/day). After one week the dose can be increased to 5 mg/kg twice daily (10 mg/kg/day). If the person doesn't respond to this dose, the maximum recommended is 10 mg/kg twice daily (20 mg/kg/day). In some research, higher doses of up to 50 mg/kg daily have been used. There is no strong scientific evidence that nonprescription cannabidiol products are beneficial for epilepsy.

Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.


Customers should always request third party lab results that test for potency, pesticides, residual solvents, and mycotoxins of the CBD hemp oil. If a company is reluctant to share these results with you, it should automatically be a red flag and indicate that they have something to hide. We’ve done the work and checked if these brands offer those tests to their customers. We’ve assigned a letter grade of C, B, A, or A+ based on what kind of lab results are offered to customers. All the brands on this list at least offer tests showing the levels of CBD and THC in them (with THC under the legal limits for hemp of 0.3%), but brands which go further are rated higher.
For example, the first study into the benefits of cannabis in veterans with otherwise untreatable post-traumatic stress disorder is beginning in 2017, but only after the researchers involved struggled through years of red tape and put their careers at risk in order to do promote the need for this vital research. Fortunately, their work, and that of others like them, have begun to peel back the bureaucracy preventing scientific research.
“Acute CBD administration by the oral, inhalatory or intravenous route did not induce any significant toxic effect in humans. In addition, chronic administration of CBD for 30 days to healthy volunteers, at daily doses ranging from 10 to 400 mg, failed to induce any significant alteration in neurological, psychiatric or clinical exams. Finally, in patients suffering from Huntington’s disease, daily doses of CBD (700 mg) for 6 weeks did not induce any toxicity. Therefore, confirming results from animal studies, the available clinical data suggest that CBD can be safely administered over a wide dose range.“

Topicals – Topicals are typically salves or creams that have been infused with cannabis or hemp oil. This allows for easy use to treat problem areas. Many senior citizens use topicals for arthritis or other auto-immune disorders however because of restrictions imposed by various agencies we are not allowed to say whether this is an effective treatment or now. However, a quick Google search will help you find what you are looking for in terms of effectiveness.
I have taken MSContin for about 15 years for kidney pain. When I changed doctors they suggested CBD oil which is legal in AZ. So while I was detoxing from taking less of the MS Contin I started the CBD oil in capsules. I had nausea and diarrhea which I contributed to the withdrawal. Both became worse. My doctor prescribed anti nausea medication. It didn’t help, nor did vaping THC. I stoped taking the CBD oil and in a day symptoms disappeared. I waited a few days and took a capsule and the nausea returned. I have been able to cut my MS Contin dose to less than half, still way too pain but am afraid to go back up or try CBD oil again. I was really hoping to stop taking morphine.
This is the second time Moon Mother Hemp Company has placed among the top five brands on our ranking. The Colorado-based company, which was founded about a year ago, sets the bar very high for quality (including USDA-certified organic hemp) without charging the moon for its products. Their tinctures taste so good, you may be sad you don’t need more.   

Pioneers of the CBD industry, 4 Corners Cannabis helped pave the way for companies that want to provide quality products and utilize best practices. They grow their own strain of hemp and make small batches of true full-spectrum CBD products. Their prices place them lower down on our ranking, but their highly satisfied customers are more than willing to pay for the 4 Corners quality.  
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.
In fact, not only will CBD not make you high, it has been proven to counteract the psychoactivity of THC. This property makes CBD highly useful as a medical treatment for a wide range of conditions. In terms of the CBD products you can buy, the amount of THC present varies from none at all in a pure CBD Isolate to a minimal amount (less than 0.3%) in a Full-Spectrum CBD product.
I was scanning reviews to see if anyone else had my experience. I purchased and tried a full spectrum CBD oil called Zilis ultra Cell. I researched after purchase and found it was a pyramid system product. Which usually offer great products, but pricey because of their system. I found that my asthma after the 1st day, was not as acute and less wheesie. However, I also took a dropper full at night twice. Both times my body was hot flashing, full body sweat- waking me up at night. My bowel movements changed to diarrhea with a spot of blood for two days. My health issue is always my lungs. Lately antibiotic help was temporary. So I thought I’d try CBD. After more research, I may have exposed that my lung issue may stem from colon issues. Worse case for me at this moment as this happened in this past week,…I may be first stages of colon cancer. This was a healing crisis, I am better every day. My next step is to do a colon test to be sure and to proceed with healing. Not afraid, just concerned and pro-active.
