I'm well aware of our history. What you are proposing though doesn't do anything but use your blood in the exact same manner Shirabuki currently does. Say you created a batch of tablets with your own blood for the purpose of eliminating the effects of Shirabuki's--what if they refused to take it? Would you force them? Is that any better than what she's doing? What if another pureblood decided they wanted to 'help'? Would the other purebloods be allowed to create them, or are you the only one given a special privilege? What gives you the right to do that? How would you select who would be allowed to have your blood? Would people take Shirabuki's tablets just for a quick way to get blood from two different purebloods and the powers contained within?
It's thoughtless. You haven't thought it through at all.
