It sounds like you're only gonna need a little at a time, but over an extended period. Personally, I'd take it fresh every time.
Mix's Method:
Let your passive hand ["left" if you're a righty] hang by your side for a couple of minutes. This allows gravity to drag blood down into your digits. Now, bind your thumb below the knuckle with a cord or cloth [I use a handkerchief]. Your thumb will now look swollen and darker. The blood inside is now at such pressure, you'll hardly have to break the skin to bleed.
Either stroke a sharp blade [gently] across the knuckle, or pepper the area with pinpricks. Both methods involve very little pain or permanent damage, and squeezing against the binding will speed up the flow. Once you have enough, release the binding and bleeding will stop. If the flow dries up before you are finished, release the binding, let your arm hang, then rebind and repeat. NB, the cut or pinpricks will reopen when you squeeze.
All the best with your endeavour. |
