I take standardized pills. Curcumin absorption is low as it is and the powder isn't as powerful as the extract. It can be given intravenously but I opted not to do it. It is not FDA regulated and I had no way of verifying its safety. Compounded drugs are not under the same scrutiny as drugs made at a plant where GMP must be maintained. Cost is another issue. As for efficacy, honestly curcuminoids are well studied for their effects on cancer. They may be a frontline drug or adjunct therapy in the future.
I have no information on aloe arborescens. It didn't come up in any of the CAM databases that I recall.
