Cannabidiol also is found in cannabis plants, but usually at much lower levels, unless the cultivar has been bred for a high CBD content. The primary source of most CBD on the market today is from the agricultural hemp plant. Over  10,000 years ago, hemp was one of the first plants spun into fiber and it is also one of the fastest growing plants in the world.

In the USA the legal definition of “industrial hemp,” per Section 7606 of the Agricultural Appropriations Act of 2014, is “INDUSTRIAL HEMP — The term ‘‘industrial hemp’’ means the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis.”
Medterra 500 mg CBD Tincture Isolate (tasteless) micro dosing is working for me! I was drawn to this company because its grown in Kentucky, close to home. After this 60 yr old lady was diagnosed with Fibromyalgia some 20+ yrs ago Im having less muscle pain, increased energy, breathing better, & more restful sleep. Wish I had known about this product years ago! Getting ready to place my 2nd order.

My mom has terminal metastatic breast cancer and her bone metastases are incredibly painful. Not only does this product keep her pain tolerable but it has also decreased her depression and anxiety significantly. She no longer has those ups and downs but finally feels GOOD. Thank you for giving my mom her quality of life back so we can truly enjoy our time with her. For reference she takes 1000 mg 2xday.
99% of the time marijuana has a high amount of THC and only a very low amount of CBD. Hemp, on the other hand, naturally has a very high amount of CBD in most instances, and only a trace amount of THC. Fortunately, the cannabinoid profile of hemp is ideal for people looking for benefits from cannabis without the ‘high.’ Hemp is used for making herbal supplements, food, fiber, rope, paper, bricks, oil, natural plastic, and so much more, whereas marijuana is usually used just recreationally, spiritually, and medicinally. The term cannabis oil can refer to either a marijuana or hemp derived oil, since marijuana and hemp are two different forms of cannabis.

CBD oil is derived from cannabis plants that have high levels of cannabidiol (CBD) while having low levels of THC. At PureKana, our CBD oils always have less than 0.2% THC. These extracts can then be used in paste form, or mixed with other oils such as hemp seed oil, to lower the viscosity of the extract. The cannabidiol (CBD) content of CBD oil varies tremendously, since the manufacturers use a varying assortment of cannabis plants and preparation techniques. We produce CBD oil with a high concentration of CBD and containing 0.02% THC.
It is for this reason that all the finished hemp goods that you see for sale in America, from food products to clothing to building materials, are part of an imported hemp industry that has surpassed $688 million annually. The size of this import industry is one of the major catalysts for hemp legalization in the U.S. As a renewable source of a range of products, hemp provides an exciting new step in American agriculture.
Tammy et al, Through trial and error you will find a correct dosage. Try 50 mg daily....25 each 2x daily....if no results up the dosage until it works for you. Remember, there has never been a death from marijuana or CBD use. You might want to try a tincture or rub with CBD and THC. You won't get the psych high from it. Helps my friend with PArkinsons tremors. She takes 50mg of tincture and uses the rub morning and night. It is a miracle for arthritis. Good luck
I was so excited to try this but it hasn’t helped my back pain whatsoever. I’ve been taking it for 2 months and I’m going to give it one more month. I am taking the 500 and have doubled the dose making it 1000 mg. So disappointed.I thought in the beginning that it was giving me a little more energy. Maybe it has. I love the company. It is so easy to order and it’s shipped right away.
Ive been taking CBD tincture oil for 8 months now. It has made such a positive improvement in my life. I have more energy and I feel better overall. I feel like myself after many years of an overall feeling of lethargy. After taking CBD oil for 6 months, I went to my doctor for a regular check up. All my my bloodwork test results- including A1C and cholesteral- improved. As an added bonus, I lost 25 lbs. All of this without even trying. Adding CBD to my life has given me more energy. I feel like my metabolism has improved. Nowadays, I look forward to each day as what can I do today, while before CBD, my attitude was negative and what do I have to do today. Nothing else in my life has changed. In fact, it has become more stressful due to family illness. But CBD has taken the edge off and continues to be my go-to daily supplement. I use Medterra 500mg tincture oil and take 1/2 a dropper twice a day. Everyone is different, so adjust the amount and strength until you find what works best for you. Definitely do it. Take CBD. Youll be so happy that you did.

There has been little high-quality research into the use of cannabidiol for epilepsy, and what there is is limited to refractory epilepsy in children.[16] While the results of using medical-grade cannabidiol in combination with conventional medication shows some promise, they did not lead to seizures being eliminated, and were associated with some minor adverse effects.[16]
A CNN program that featured Charlotte's Web cannabis in 2013 brought increased attention to the use of CBD in the treatment of seizure disorders.[67][68] Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions.[69] This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content.[69] Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.[69]
Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[42] In strongly basic media and the presence of air, it is oxidized to a quinone.[43] Under acidic conditions it cyclizes to THC,[44] which also occurs during pyrolysis (smoking).[45] The synthesis of cannabidiol has been accomplished by several research groups.[46][47][48]
