How to Extract CBD – Cannabis Extraction Methods Explained

The CBD Extraction Process. CBD extraction serves one purpose; to isolate the target chemical compounds from the hemp plant, and eliminate all the unwanted compounds — like fiber, minerals, and plant sugars. Extracting CBD from cannabis calls for selectively-bred, high-CBD marijuana strains, or various strains of hemp. Selective breeding results in strains high in the target cannabinoids, such as .
