Dandelion Root for Leukemia and Other Cancers


Research on Dandelions and Cancer 

Siyaram Pandey, a biochemist at the University of Windsor, has been studying the anti-cancer potential of dandelion root extract for over two years.  The team’s first phase of research showed that dandelion root extract forced a very aggressive and drug-resistant type of blood cancer cell, known as chronic monocytic myeloid leukemia, to essentially commit suicide.

Researchers then discovered that repeated treatment with low dose dandelion root extract was effective in killing most of the cancerous cells. Those initial findings landed the research team a $60,000 grant from Seeds4Hope, which provides money towards local cancer research. Pandey then applied for continued funding from the Lotte and John Hecht Memorial Foundation, and received the additional $157,000 to continue their study.

Pandey admits he was skeptical when he was first approached by local oncologist, Dr. Caroline Hamm, who was curious about cancer patients who had been drinking dandelion tea at their own initiative and seemed to be getting better.  “To be honest I was very pessimistic,” Pandey said in a statement. “She said it could be coincidental, but it couldn’t hurt to see if there is anything to this.”

Pandey conducted a literature review and could only find one journal article suggesting dandelions may have cancer-killing properties, but he and his team of graduate students collected a bunch of the weeds and ground up their roots with a mixture of water in a food processor and developed a simple formula they could experiment with.  They tested the formula on several lines of commercially available leukemia cells and much to their surprise, found that the formula caused those cells to commit suicide in a process called apoptosis.  “It was startling, but it was not that startling until we saw that it was non-toxic to the normal cells,” he said.

Clinical studies with dandelion

In the past few years, results of clinical research have been published in several prestigious publications regarding the benefits of dandelion for those with cancer. In 2008, the results of a clinical study showing the positive effects of dandelion on breast cancer cells were published in the International Journal of Oncology

  • The findings on prostate cancer were corroborated by a report published in 2011 by the International Journal of Oncology, which showed that a dietary supplement containing dandelion suppressed the growth of prostate cancer cells.
  • Dandelion root extract was clinically proven in 2011 to specifically induce apoptosis in chemo-resistant melanoma (a type of skin cancer)—without toxicity to healthy cells.

John DiCarlo heals his terminal Leukemia by drinking dandelion tea

John DiCarlo, 72, was admitted to the hospital three years ago with leukemia. Even after aggressive treatment, he was sent home to put his affairs in order with his wife and four children.  At the time, the cancer clinic suggested he try drinking dandelion tea. Four months later, he returned to the clinic in complete remission, and has been cancer free for over three years.  He said his doctor credits the dandelion tea that he had been drinking. Link to the article. 


While there are no negative side effects from taking the dandelion herb, some people may have allergic reactions to it. Those may include a rash or mouth sores. If you are allergic to yarrow, iodine, ragweed, marigold, chrysanthemums, chamomile, or daisies, you may also be allergic  to dandelion. Dandelion might cause stomach acid or heartburn in some people, try cutting back your dosage and then slowly building up to see if that helps alleviate the symptoms. If you have gallbladder problems or gallstones, you should consult a doctor before taking dandelion. Dandelion is a diuretic and may cause your body to dehydrate, so keep your fluids up by drinking throughout the day. Consult a doctor if you are taking other medications.
