A Meghan Markle superfan is threatening to sue the Duchess of Sussex for £8million ($10million) after suffering “catastrophic burns” while copying a homemade bath salt recipe featured on Meghan’s new Netflix series With Love, Meghan.

Robin Patrick, a diabetic from Maryland, said she sustained severe injuries after using the same blend of salts Meghan prepared as a wellness gift for makeup artist Daniel Martin. The mix included Epsom salt, Himalayan salt, arnica oil and lavender oil—but Robin claims it left her with painful ulcers, blistering skin and fears of serious complications.

Speaking to RadarOnline.com, Patrick said: “Initially, I experienced a mild tingling sensation without discomfort. However, as the water level rose to cover my legs and reached my buttocks, I began to feel burning and significant discomfort in those areas. I immediately exited the tub, stopped the water, and later stirred the bathwater with my right hand and arm to assess the mixture. This resulted in additional burning sensations on my hand and arm. After draining the tub, I applied Gold Bond lotion, which provided no relief followed by lidocaine sprays which temporarily alleviated the pain.
