Congressman’s wife died after taking white mulberry leaf, an herbal remedy

SACRAMENTO, Calif. — The wife of a Northern California congressman died late last year after ingesting a plant that is generally considered safe and is used as an herbal remedy for a variety of ailments, including diabetes, obesity, and high cholesterol, KHN has learned.

Lori McClintock, the wife of U.S. Rep. Tom McClintock, died from dehydration due to gastroenteritis — an inflammation of the stomach and intestines — that was caused by “adverse effects of white mulberry leaf ingestion,” according to a report from the Sacramento County coroner that is dated March 10 but was not immediately released to the public. KHN obtained that report — in addition to the autopsy report and an amended death certificate containing an updated cause of death — in July.

The coroner’s office ruled her death an accident. The original death certificate, dated Dec. 20, 2021, listed the cause of death as “pending.”

Tom McClintock, a Republican who represents a district that spans multiple counties in northern and central California, found his 61-year-old wife unresponsive at their Elk Grove, California, home on Dec. 15, 2021, according to the coroner’s report. He had just returned from Washington, D.C., after voting in Congress the night before.

It’s unclear from the autopsy report whether Lori McClintock took a dietary supplement containing white mulberry leaf, ate fresh or dried leaves, or drank them in a tea, but a “partially intact” white mulberry leaf was found in her stomach, according to the report.

McClintock’s death underscores the risks of the vast, booming market of dietary supplements and herbal remedies, which have grown into a $54 billion industry in the United States — one that both lawmakers and health care experts say needs more government scrutiny.

Many people assume if that product is sold in the United States of America, somebody has inspected it, and it must be safe. Unfortunately, that’s not always true,” U.S. Sen. Richard Durbin (D-Ill.) said on the Senate floor this spring when he introduced legislation to strengthen oversight of dietary supplements.
