The Gunner has opted for the bizarre treatment following a recommendation from PSV Eindhoven striker Danko Lazovic.
The 26-year-old star has been ruled out for six weeks but claims Arsenal doctors have given him their blessing to pursue the strange treatment.
He said: "I will fly to the Balkans to meet with a female doctor who helped Lazovic.
"She is vague about her methods but I know she massages you using fluid from a placenta.
"I'm going to try. It cannot hurt and if it helps, it helps.
"I've been in contact with Arsenal physiotherapists and they have let me do it."
