For applications where pure CBD isn’t required, full spectrum CBD oil is the better alternative, as it provides patients the ancillary benefits associated with the many other cannabis compounds. However, important to note, is the issue of what medical conditions are best treated by either pure or full spectrum CBD oil, given the research is in its infancy. 
Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.)
Considered the most scientific method this is also among the cleanest techniques of extraction. Referred to as sub-critical or super critical CO² method, it uses carbon dioxide under different pressures to extract the medicinal oil. This is among the most expensive techniques of extraction due to use of hi-tech equipment that can be operated by trained personnel only. The advantage of this technique is that the end product is the purest form of CBD oil which is highly potent and free of chlorophyll. However if the heat used during extraction is too high it can damage terpenes in the oil that have therapeutic benefits and provide flavor and essence to the oil strain.
With the rapid rise in the popularity of CBD in everything from vape juice to lattes, many people are asking- “what is CBD oil?”. To answer that question, let’s first answer the question- what is CBD? CBD, short for cannabidiol, is a compound found in hemp plants. CBD’s benefits are numerous, making it a popular supplement. We’ll explore the effects of CBD oil in more depth below, but in short, it interacts with receptors that keep the body balanced and running normally.
