A California dermatologist accused of poisoning her husband with Drano in his lemonade says she did nothing of the sort and that her husband made up the accusations to get custody of their children.

Emily Yu, 45, was suspended from her job after her arrest last week, KCBS reported.

Her husband — radiologist Jack Chen — told police he had been sick for months and noticed a chemical taste in his lemonade. He reportedly captured images of Yu pouring Drano on three separate occasions and brought the pictures to Irvine police.

But David Wohl, Yu’s attorney, said the idea that Yu “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.”

Wohl said each time Yu was seen with Drano she was using it to unclog a drain and that she poured it into a “completely empty” cup at first to avoid splashing.

“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 said. “But she never poured any Drano or any chemical into any drink that the father or her husband used or was drinking ever. That’s completely untrue.”

KCBS said that Chen, 53, had been diagnosed with stomach ulcers, gastritis, and inflammation of the esophagus.

Wohl said his client has no idea how Chen could have ingested Drano — or even if he actually did.

“But we do know that he was desperate for a divorce filing,” said Wohl. “He was desperate to have reasons to gain custody of the children. We believe completely that these claims he made are all part and parcel of that effort.”

Chen’s lawyer denied Yu’s accusations.

Yu has been released on bail.
