Saint Bernard prayed to Mary, asking her to prove she was a mother. She obliged by squirting milk in his eye
She also took pity on the souls in Purgatory and with help from Her Baby, she showered them too
There are other uses for breast milk. The artists at Dezeen have solidified its casein content into a form of plastic and created jewellery and ornaments.
Christians have long been believed in the power of relics salvaged from various parts of dead saints including Mary. Her breast milk was supposedly collected in vials. Then again, Jesus’s foreskin and baby teeth are also allegedly owned by various churches, as are numerous pieces of the cross he was crucified upon.
In 390 C.E., two monks found not just one, but two heads of John the Baptist. Many relic manufacturers concentrated on Virgin Mary memorabilia. They produced her hair, her bones, her girdle, her grave-clothes, and her virginal milk. One church claimed to own Mary Magdalene’s forehead and even one of her breasts. A church in France that supposedly owned one of Mary’s arms was visited by a bone collector who actually tried to chew off one of Mary’s fingers in order to add it to his collection! Even Monty Python couldn’t have written better material than this.

But milk is not the only excretion from the human body which is made into jewellery.
In Japan, human waste is specially treated with high temperatures to turn sludge into a rock-hard material. This is used as gravel for making roads and jewelry is made from it. I am not sure if there are any beads of this stuff, but cufflinks are available.
And of course there’s always Art. Manzoni and Wim Delvoye have both produced art from shit, with Delvoye’s Cloaca Machines being exhibited all over the world and Manzoni’s Artist’s Shit selling for 124,000 euros per can.
