Massive Amount of Lead Discovered in San Franciscan's Herbal Remedy

Lead is bad for people, and it's particularly bad for children, older folks, and anyone with kidney problems. So when a 60-year-old South Asian man walked into Dr.Vivek Bhalla's office with diabetes and kidney disease, and his lead levels tested three times higher than what's acceptable, that was a big problem.

It became crucial to find out how the lead poisoning was getting into the man's body, and Dr. Bhalla, at the time working at San Francisco General Hospital, enlisted an investigator from the San Francisco Department of Public Health to figure it out.

The job went to environmental health investigator Ihsan DuJaili, who interviewed the man and learned that he was taking an herbal supplement from India, commonly referred to as an Ayurvedic remedy. There are many different kinds, and these particular, unnamed tablets were round and golden. DuJaili sent them to a lab, and the test results showed that the tablets had "massive" amounts of lead. The man -- who believed that the Ayurvedic remedy was helping his kidneys -- had been swallowing one a day.

He's not the first, and its likely he won't be the last. Studies have shown that approximately 20 percent of Ayurvedic remedies contain toxic metals such as lead, mercury, and arsenic. In South Asia where the remedies are prepared, there is a practice called Rasa Shastra, which involves infusing herbal remedies with metals, gems, and minerals that are considered therapeutic. Unfortunately, that also increases the likelihood that toxic metals will find their way in. 

When asked if he thought many others had been harmed by their Ayurvedic remedies, investigator DuJaili -- who in the past decade has identified dozens of sources of lead poisoning -- said, "I have no doubt." 

Dr. Bhalla instructed the man to immediately stop taking the golden tablets, and also began treating him for the lead contamination. The man's lead levels returned to normal. "I'm fairly confidant that if we did not do what we did, it would have adversely affected his kidneys," said Bhalla.

The successful collaboration between the doctor and the investigator, along with Dr. Suma Prakash, resulted in a case study published this month in Nature Reviews Nephrology, a monthly magazine on kidney health.

  • clipping at Brava Theater Sept. 11
    Sub Pop recording artists 'clipping.' brought their brand of noise-driven experimental hip hop to the closing night of 2016's San Francisco Electronic Music Fest this past Sunday. The packed Brava Theater hosted an initially seated crowd that ended the night jumping and dancing against the front of the stage. The trio performed a set focused on their recently released Sci-Fi Horror concept album, 'Splendor & Misery', then delved into their dancier and more aggressive back catalogue, and recent single 'Wriggle'. Opening performances included local experimental electronic duo 'Tujurikkuja' and computer music artist 'Madalyn Merkey.'"
