The 42-year-old actress held nothing back when she wrote her latest blog post, choosing to discuss some very personal topics.
The mum-of-three told her fans about steaming her vagina to help ‘balance female hormone levels.’
On her lifestyle website, Goop, Gwen wrote: "Tikkun is the next level when it comes to Korean spas, combining high-tech far infrared heat with traditional Korean sauna therapies.
"So, if you want to lay down in a Himalayan salt brick tiled sauna, or sit in a Hwangto clay room, you get the added benefit of far infrared heat.
"And, in addition to the sauna rooms, there's a long menu of massages and kick-ass body scrubs to complement the sauna time.”
Gwyneth added: “It is an energetic release - not just a steam douche - that balances female hormone levels. If you're in LA, you have to do it."
The actress has been a long-time supporter of alternative therapies and treatments, including a strict vegetarian and gluten-free diet.
