Experts Question the Role of White Mulberry in the Death of Congressman’s Wife

SACRAMENTO, Calif. — Scientists, medical doctors, and pathologists are questioning the Sacramento County coroner’s conclusion that Lori McClintock’s demise was associated to white mulberry, a plant that has been used as an natural treatment for hundreds of years — and one which the coroner’s botanical guide called “not toxic” in a letter to her workplace.

McClintock, the spouse of U.S. Rep. Tom McClintock (R-Calif.), died out of the blue in December from dehydration due to gastroenteritis — an irritation of the abdomen and intestines — that was attributable to “opposed results of white mulberry leaf ingestion,” in accordance with a report from the Sacramento County coroner. The coroner dominated the demise an accident.

However Sacramento County Coroner Kimberly Gin has not defined — nor supplied data that designate — why she decided white mulberry leaf led to the dehydration that killed McClintock at age 61, fueling skepticism amongst quite a lot of specialists.

A “partially intact” white mulberry leaf was present in Lori McClintock’s abdomen, in accordance with the post-mortem report. However there isn’t a different reference to her use of white mulberry leaves, dietary supplements, extracts, powders — or every other technique of ingesting the plant — within the documents the coroner’s office has released referring to the case.

“It could take actually bushel baskets of white mulberry leaves to trigger some sort of untoward impact. And even then, you don’t see something deadly,” mentioned Bill Gurley, principal scientist on the College of Mississippi’s Nationwide Heart for Pure Merchandise Analysis, which collaborates with tutorial, authorities, and business officers to analysis and develop pure merchandise.

Gurley, an skilled in herb and drug interactions, referred to as white mulberry leaf — which has been used for quite a lot of illnesses, together with diabetes, hypertension, and weight problems — “in all probability one of many most secure leaves on the earth” and mentioned “its observe file for security is unsurpassed.”

“I’m simply scratching my head as to how on the earth they might soar to the conclusion that this woman handed away by ingesting, no less than so far as we all know, just one mulberry leaf,” he mentioned.

Dr. Mary Hardy, who based the integrative drugs clinic at Cedars-Sinai Medical Heart in Los Angeles and researched the security of some different medicines and therapies for the now-closed UCLA Heart for Dietary Dietary supplements Analysis in Botanicals, mentioned the coroner’s conclusion is “not convincing.”

“The proximate reason for demise isn’t supported” by the accessible data, Hardy mentioned.

Gin, contacted by way of Sacramento County spokesperson Kim Nava, repeatedly declined interview requests from KHN and has refused to supply data that explains how her workplace concluded {that a} partial white mulberry leaf contributed to McClintock’s demise.

The leaves and fruit of the white mulberry tree, native to China, have been used for hundreds of years in conventional drugs. Tutorial research over the previous decade have discovered that the extract from its leaves can lower blood sugar levels and assist with weight loss. Folks take it in capsule or tablet type, as an extract or powder. They’ll additionally eat the younger leaves uncooked or brew leaves as an natural tea.

It’s unclear how McClintock ingested the white mulberry leaf — whether or not she ate it uncooked or drank it in a tea — and the place she acquired it.

Tom McClintock, a Republican who represents a district that spans a number of counties in central and Northern California, discovered his spouse unresponsive at their Elk Grove, California, house on Dec. 15, 2021, in accordance with the coroner’s report. He has not responded to repeated requests for remark.

At his spouse’s funeral in January, Tom McClintock advised mourners she was advantageous when he spoke along with her the day earlier than she died. However in accordance with the coroner’s report, the day earlier than her demise “she had complaints of an upset abdomen.”

McClintock additionally advised mourners that “she was fastidiously weight-reduction plan” and that “she simply joined a health club.”

KHN obtained the coroner’s report, dated March 10, along with the post-mortem report and demise certificates, in July and reported the findings in August.

The coroner’s workplace examined McClintock’s physique for the flu, different respiratory viruses, and covid-19. None were detected. It additionally commissioned impartial lab exams that confirmed McClintock’s physique had elevated ranges of urea nitrogen, sodium, and creatinine — all indicators of dehydration, in accordance with 5 pathologists interviewed by KHN. Simply considered one of them mentioned it was believable that white mulberry leaf might have contributed to the dehydration.

All of the pathologists mentioned that the coroner’s publicly launched paperwork didn’t present an entire image of how McClintock died and that it didn’t embrace key particulars comparable to what the coroner’s workplace discovered on the home, and whether or not McClintock might need been taking any drugs or dietary supplements.

“The indication that there could also be some dehydration is true. They don’t actually have a lot else to go together with,” mentioned Dr. Gregory G. Davis, director of the forensic division of the College of Alabama-Birmingham’s Division of Pathology and chief coroner-medical examiner for Jefferson County, Alabama.

“I don’t know that mulberry leaf essentially performed any position within the demise,” Davis mentioned, including, as different specialists did, that it’s not thought of poisonous.

“She appeared, taking a look at her post-mortem outcomes, like she was fairly wholesome, and also you wouldn’t have actually anticipated her to die at the moment. In order that’s already made it a troublesome case as a result of it’s not apparent.”

Dr. James Gill, chair of the School of American Pathologists’ Forensic Pathology Committee and chief medical expert of Connecticut, added it may well take days for somebody to die of dehydration. One leaf alone, which hadn’t been absolutely digested, a course of that often takes solely a few hours, wouldn’t “have contributed to demise,” he mentioned.

“It takes about no less than every week or so for somebody to die from not consuming from dehydration,” Gill mentioned. Based mostly on the accessible data, “there are some issues that actually don’t match.”

Gill mentioned he would have dominated McClintock’s demise a pure demise of unknown causes, which occurs in about 5% of his demise investigations.

No deaths from the white mulberry plant have been reported to poison management officers up to now 10 years, in accordance with the American Affiliation of Poison Management Facilities. Two circumstances of people that might have been sickened by mulberry dietary supplements have been reported to the FDA since 2002, in accordance with its database that tracks “adverse events.” FDA spokesperson Lindsay Haake declined to say whether or not the company is wanting into the case as a result of it doesn’t disclose investigations.

After KHN broke the story about McClintock’s reason for demise, the coroner’s workplace launched a few further paperwork, together with a Dec. 29, 2021, letter from Alison Colwell, curator of the College of California-Davis Heart for Plant Range. The coroner had requested Colwell to establish the 1 1/8-inch-by-1 7/8-inch leaf fragment present in McClintock’s abdomen through the post-mortem.

Colwell recognized it as white mulberry and concluded, based mostly on its flexibility and “some inexperienced coloration,” that it “was possible ingested when contemporary,” her letter mentioned.

Though white mulberry timber are frequent within the Sacramento area, she famous that their leaves in December are “powerful, yellowing and have largely fallen off of the timber.”

Colwell additionally acknowledged merely: “White mulberry isn’t poisonous.”

“I in contrast the specimen to lethally poisonous species which are recognized to be planted or are native within the Sacramento space and located no matches,” her letter mentioned. Colwell declined an interview request.

The natural merchandise business, the dietary dietary supplements business, and their allies have chafed on the risk that McClintock might have died after ingesting dietary supplements containing white mulberry leaf — not to mention a white mulberry leaf itself.

“It’s been used as a meals, used as a medication,” mentioned Rick Kingston, a clinical professor on the College of Minnesota’s School of Pharmacy. He’s additionally co-founder of SafetyCall Worldwide, an organization that helps the dietary supplements business and different purchasers log and observe opposed occasions associated to their merchandise.

The American Natural Merchandise Affiliation, which represents natural growers and producers, commissioned Kingston to assessment McClintock’s case. “I see a variety of post-mortem studies,” Kingston mentioned. “I’ve to confess this was fairly sparse when it comes to supporting knowledge.”

A number of plant specialists additionally query whether or not the leaf present in McClintock’s abdomen was white mulberry. Élan Sudberg, CEO of California-based Alkemist Labs, which conducts botanical plant testing for the dietary supplements business and different purchasers, mentioned Colwell’s letter lacks particulars of her evaluation of the leaf that may assist others studying the report definitively establish it as white mulberry. Both that, he mentioned, or the leaf wasn’t white mulberry.

He mentioned the coroner ought to launch extra data, reopen the case, and conduct extra rigorous exams.

“I’d like to see a reexamination and perceive why they went to the conclusion that she died from a principally inert leaf,” Sudberg mentioned.
