Hollywood celebrities are trying their hand at Rakta Moksha detox techniques too. While most people squirm at the thought of blood sucking leeches, celebrities like Demi Moore are swearing by leech therapy to keep themselves toxin free and youthful. According to US Magazine, leeches are Demi Moore’s secret to looking sexy at the age of 45.

“I feel like I’ve always been someone looking for the cutting edge of things that optimize your health and healing,” she told David Letterman when she appeared as a guest on his show a few months ago. Demi describes how four leeches got drunk on her blood, starting from her bellybutton, and how they don’t like hair and prefer waxed or shaved skin.

While Moore actually appeared on Letterman’s show to promote her movie Flawless, most of the conversation focused on how leech therapy has kept her health flawless. Check out the video for yourself:
