A naturally occurring compound derived from the ashwagandha plant is demonstrating potential benefits in the treatment of B-cell lymphomas, a type of cancer affecting the lymphatic system. Researchers at the University of North Carolina (UNC) School of Medicine have discovered that this chemical disrupts processes within cancer cells that often render them resistant to conventional chemotherapy, offering a potential new avenue for therapeutic intervention.
Lymphomas, cancers that begin in the lymphatic system, can be challenging to treat due to their ability to evade standard therapies. The UNC study, published in February 2026, focuses on B-cell lymphomas, a common subtype. The findings suggest that a specific withanolide, a chemical constituent of ashwagandha (Withania somnifera), interferes with critical mechanisms that contribute to treatment resistance, potentially enhancing the effectiveness of existing chemotherapy regimens.
Ashwagandha, a foundational herb in the ancient Indian medical system of Ayurveda, has been used for over 3,000 years as an adaptogen – a substance believed to help the body resist physical and biological stressors. Whereas traditionally used to alleviate anxiety, reduce fatigue and improve overall health, recent research is uncovering its potential role in cancer treatment. The focus of this new research is on withaferin A (WA), a specific withanolide found within the plant.
Withaferin A Targets Key Cancer Processes
The research highlights that withaferin A inhibits the survival of both human and murine B cell lymphoma cell lines. According to a study published in PubMed, WA disrupts the efficiency of NF-κB nuclear translocation, a process crucial for the growth and survival of lymphoma cells. The compound appears to reduce protein levels involved in B cell receptor signaling and cell cycle regulation. This disruption, researchers believe, stems from WA’s ability to inhibit the function of heat shock protein (Hsp) 90, leading to a decrease in critical kinases and cell cycle regulators.
The study also indicated that WA inhibited tumor growth in animal models without affecting other proliferative tissues, suggesting a degree of selectivity in its action. This is a crucial finding, as many cancer treatments suffer from significant side effects due to their impact on healthy cells.
Ashwagandha and Cancer: A Broader Perspective
While the UNC study focuses on a specific compound and its mechanism of action, broader research explores the potential of ashwagandha in cancer care. Memorial Sloan Kettering Cancer Center (MSK) notes that ashwagandha may reduce stress, anxiety, and insomnia – common experiences for cancer patients undergoing treatment. Jason Hou, a pharmacist at MSK’s Integrative Medicine Service, explained that the herb’s popularity stems from patients seeking non-pharmaceutical options for stress relief.
However, MSK emphasizes that there is currently no data to support the use of ashwagandha to prevent or treat cancer directly. Laboratory and animal studies have shown anti-inflammatory properties, but these findings haven’t yet translated into clinical evidence for cancer prevention or treatment. Despite this, MSK does prescribe ashwagandha at its herbal dispensary, recognizing its potential benefits in managing stress and improving quality of life for some patients.
Enhancing Conventional Treatments?
Beyond its potential to directly target cancer cells, some research suggests ashwagandha may enhance the effectiveness of conventional cancer treatments. Ashwagandha.com reports that animal studies indicate the herb can increase the effectiveness of radiation therapy while simultaneously protecting healthy cells from negative side effects. These studies involved mice with fibrosarcoma and treatment-resistant melanoma tumors.
It’s important to note that research into ashwagandha’s anti-cancer properties is ongoing. A recent study, as reported in The Journal of Oncology, acknowledges the numerous research data supporting the herb’s benefits but highlights the limited use of ashwagandha in clinical cancer treatment.
The potential of ashwagandha and its compounds, like withaferin A, in lymphoma treatment represents a promising area of investigation. Further research, including clinical trials, is needed to fully understand its efficacy, safety, and optimal use in conjunction with existing cancer therapies. The next steps will likely involve larger-scale studies to confirm these initial findings and explore the potential for developing ashwagandha-based therapies for lymphoma and other cancers.
This research offers a glimmer of hope for individuals battling lymphoma, but it’s crucial to remember that ashwagandha should not be considered a substitute for conventional medical care. If you have questions about cancer treatment options, please consult with a qualified healthcare professional.
