Have you ever met someone that is totally overanalytical? Was not content enough with the answers given? Had to analyze it more....and more. Had to delve in deeper and deeper until they make the results they wanted in the first place......finally come to light.
I've seen people do this with their relationships with other people. They question them and question them.....wanting an answer that may not even exist. Finally, the friend caves and just says what the other wants to hear just to make the conflict stop and go away.
Police officers do this when questioning a suspect.
Scientists may be so determined that they try an experiment over and over and over again until they find the results they want.
Regardless.......to get blood out of a stone, it usually means we have someone so closed minded and so focused on one result that they will never move beyond it until they find get what they want.

It depends on the type of stone, the porosity distribution and whether the stone was wetted with a different fluid first.
In the Oil industry we worry a lot about the removal of fluids from rocks which is an extension of your problem. If the oil/blood flows naturally you can just collect it but this is rarely the case as capillary action tends to hold the majority of the fluid inside the pore spaces.
Our solutions are fairly drastic namely liquid nitrogen fracturing and using high explosives to perforate the rock. If you have a stone that is permiated with fluid you could try crushing it if you are sure the grains won't absorb the fluid. As a last resort try high pressure steam.

Actually this phrase is based upon a real physical problem, not just some old myth.
Limestone is porous. If subjected to blood, human or animal, the blood will seep into the pores and discolor the stone. The original problem, then was learning how to remove the rust colored blood stain from limestone altars.
Weak hydrochloric acid might work but had a tendency to etch the limestone. One enterprising young alchemist came up with an extract of the sorrel plant that did a reasonable job. The plant juice contained oxalic acid, which is now known to chealate with iron.

"You cannot extract what isn't there to begin with."
For example, how do you get money out of a poor person? That is the original meaning of the term. The term also extends to getting water out of rocks as evident by the Old Testament miracles.

There are a lot of people named Stone and many of them are blood donors.
