Mad Men actress has advised women to eat their own placentas after birth, claiming it helped her avoid depression and fatigue.
Jones, who plays Betty Draper in Mad Men, had her own placenta dehydrated and turned into capsules after having her only son, Xander, now 16 months old.
She has now told Glamour magazine it is a “very civilised thing which can help women with depression and fatigue”.
“I was never depressed or sad or down after the baby was born, so I’d highly suggest it to any pregnant woman,” she told the April edition of the magazine.
Saying she should “never have told anybody about that” because of the fuss it caused, she added: “It’s not gross or witchcrafty”.
Jones, who returned to work six weeks after giving birth, first revealed she had eaten her placenta last year, when she admitted she had been “very hesitant about it” at first.
At the time, Catherine Collins, principal dietician at St George's Hospital in London, said: "Nutritionally, there's nothing to be gained from eating your placenta.”
The actress, 34, also spoke of her role in Mad Men, which she says inspired women to approach her in the street to sympathise about her suave fictional husband Don Draper treating her badly.
“That’s when I knew it had become so much more than just a TV show. It was a cultural phenomenon,” she said. “Fashions were changing as a result of the show. It was like the 60s were back.”
She disclosed the popularity of the show meant the cast are only given their scripts a day before shooting, to keep the storylines under wraps.
