Her upcoming lectures on “natural self-healing” have raised concerns among medical experts who warn that such misinformation could lead vulnerable patients to delay or reject proven cancer treatments.

Despite the ban, she continues to attract audiences internationally, highlighting ongoing challenges in regulating health misinformation across borders.
