This was the first MHRB tek on the net for extracting the desired alkaloid from MHRB using broken or solid pieces of root bark without the need to powder the material but is actually a better process for powdered. This tek works great with broken pieces of bark but takes longer than if you first powder the bark. That is the only real difference between using either form of bark, less time if powdered, but I also believe if you let powdered material sit much longer in the NaOH basified water it will have higher yields than if only doing a quick extraction when powdered.
