“I’ve been aware of and interested in cannabis extracts for 40 years. As an oncologist, I began recommending cannabis to cancer patients for palliation of nausea, pain and anorexia after Proposition 215 was passed in California. I had heard anecdotes of occasional major tumor responses of cancer patients over the years, but it wasn’t until I met Constance and began to interview her patients that I saw these on a regular basis. Cannabis extracts of the proper type and amount, appear to be one of the most useful botanical medicines in supporting cancer patients.”– Dwight McKee MD, CNS, ABIHM, Diplomate American Boards of Medical Oncology and Hematology.

CBD-rich cannabis oilWhat Makes Our Cannabis Oils Different?

Our cannabis extracts are not processed from byproduct (or “trim”) often found in nonmedical cannabis products or in competing medical cannabis oils. We use only the most valuable portion of the Northern California grown female cannabis plant. We do not use butane or other illegal processes in our oil extractions. Read more about how our medical cannabis oils are different.
