A proponent of “slapping therapy” for various ailments received a 10-year prison sentence on Friday for the death of a 71-year-old diabetic woman who discontinued her insulin during one of his workshops.

Hongchi Xiao, 61, was found guilty of manslaughter for failing to seek medical attention for Danielle Carr-Gomm, who experienced severe pain and distress during a workshop in October 2016.

Xiao, from Cloudbreak, California, promoted paida lajin therapy, a practice involving repeated self-slapping to purportedly expel toxins. While rooted in Chinese medicine, critics cite its lack of scientific basis, with patients often suffering injuries ranging from bruises to bleeding, and in some cases, death.

Carr-Gomm was one of two patients of Xiao’s who died.

He was extradited from Australia, where he had previously been convicted of manslaughter following the death of a 6-year-old boy whose parents stopped his insulin treatment after attending a workshop in Sydney.

“I consider you dangerous, despite not fitting the profile of most dangerous offenders,” Justice Robert Bright stated during sentencing at Winchester Crown Court.

“You were aware from late afternoon on the first day that Danielle Carr-Gomm had stopped her insulin,” the judge noted. “Moreover, you explicitly condoned this.”

Bright described Xiao’s efforts to have Carr-Gomm resume insulin as minimal and noted his continued promotion of paida lajin while imprisoned, showing no remorse.

Carr-Gomm, diagnosed with type 1 diabetes in 1999, desperately sought a cure avoiding injections, according to her son, Matthew.

She pursued alternative treatments and had participated in a prior workshop led by Xiao months before her death, during which she also experienced severe illness after halting her medication.

Despite this, she created a video testimonial praising Xiao as a “messenger sent by God,” initiating “a revolution to empower people to cure themselves and reform healthcare.”

Xiao commended Carr-Gomm for ceasing her insulin treatment in front of other participants at the English retreat.

By the third day, Carr-Gomm was “vomiting, fatigued, and weak, and by evening, she was screaming in pain and unresponsive,” prosecutor Duncan Atkinson stated.

A chef present who wished to call an ambulance said she deferred to others with holistic healing experience.

“Those who embraced the defendant’s teachings misinterpreted Mrs. Carr-Gomm’s condition as a healing crisis,” Atkinson explained.
