This is another Accupuncture method to bring a very dangerous temperature down fast.
You gently prick the centre of the tips of the fingers and draw a drop of blood from each finger. Be very careful to protect yourself because the blood could contain greeblies, and they could be extremely dangerous greeblies.
Personally, I’ve used a Yarrow and elderflower infusion that works very fast, but I’d use this in a severe case if the person is too sick to drink and the temperature is high enough to mess with the brain and cause fits.
Once again, no different to taking out a splinter…
