Doctor Yue Yu insists she was using Drano for cleaning, not poisoning

The California dermatologist who was caught on a nanny cam allegedly pouring Drano into her husband’s lemonade was using the chemicals to unclog pipes — and the man fabricated the poisoning claim as part of a custody battle, according to her attorney.

Yue “Emily” Yu, 45, was arrested last week after her husband, Jack Chen, accused her of repeatedly spiking his drink with the caustic drain cleaner. As of Friday morning, Yu had been released on bail and had not been charged with a crime.

“The idea that my client, who is a 45-year-old well-respected dermatologist in Orange County, would destroy her life, destroy her children’s lives and try to kill her husband is just completely absurd and untrue, and for that matter defamatory,” attorney David Wohl told CBS Los Angeles.

Chen’s attorney claimed that the husband, who works as a radiologist, allegedly documented his wife pouring the Drano into his hot lemonade beverage on three separate occasions at their home in Irvine.

But Wohl insisted that Yu was actually using the cleaning solution to unclog a drain. He added that what the nanny cam videos actually showed was the wife pouring the Drano into an empty cup so it would not splash.

“Anytime she poured Drano into a cup it was completely empty,” the lawyer said. “It was for facilitating use in the sink or any other part of the house that was clogged as far as the drainage goes.”

Wohl stressed that Yu never poured any Drano — or any other chemical — into Chen’s drink, saying “that’s completely untrue.”

The lawyer further argued that Chen had concocted the poisoning allegations because he was “desperate” to divorce Yu and gain custody of the couple’s two children.

“We believe completely that these claims he made are all part and parcel of that effort.” Wohl said.

Chen said through his attorney that he had been noticing a chemical taste in his lemonade and was diagnosed with stomach ulcers, gastritis and inflammation of the esophagus.

Last week, Chen filed paperwork with a court seeking a restraining order against his wife of 10 years.

He claimed mistreatment by Yu that included physical and verbal abuse of their children — even alleging that she had once yelled at them to “go die.”

“When Emily gets frustrated and yells at the children, she’ll commonly use a Chinese phrase that translates to ‘go die!’ She also says to the children, ‘your head has a problem, ‘your head is sick, ‘go f–k yourself,’ ‘f–-ing idiot,’ ‘stupid a–hole,’ and ‘get the f–k out of my way,’” Chen wrote in the court document obtained by The Post.

Yu even deprived the children, now 8 and 7, of sleep if they went to bed before she wanted them to, Chen alleged.
