Mellymelboo, and congratulations on getting a new lease on life. 
From a dispensary it’s likely to be called CCO, or concentrated cannabis oil, and yes, it’s a very adaptable product. It’s also very pricey. If using for edibles it’s helpful to infuse it into a carrier oil and add some liquid sunflower lecithin to increase bioavailability, so I find it much more cost effective to make a simple infused oil and substitute it for the oil part of the recipe. There are many ways to cover the taste.
Making CCO at home without something like a Source extractor requires the use of an expensive, hard-to-resource and dangerously volatile ethanol alcohol for the extraction. With proper precautions this is a safe process, but infusions aren’t likely to explode into a fireball if something goes wrong. One friend with second-degree burns over his hands and legs from such an accident was enough incentive to teach have me looking more seriously at infusions.
Under the right circumstances and to treat certain conditions CCO is preferred meds, but almost never necessary. It is, however, the gold standard for higher concentrations of cannabinoids. Dispensary CCO is now being made in ways that preserve the terpenes, (they call it live) so if this is an option for you @Mellymelboo I‘d grab it and we can help you work out dosing.
Just wondering about your comment about it being a decent way to support your immune system? Because my doctor told me not to take any immune booster type things because it increases the risk of rejection. Could you elaborate on what you mean please?
