Juglone — the active compound in properly aged black walnut — does two things at once:
First: It cuts off the blood supply tumors need to grow. Cancer cells cannot establish themselves without building new blood vessels. Juglone interrupts that process at the source. The tumor starves.
Second: It keeps natural killer cells strong, multiplying, and active. Your immune system's cancer-hunting soldiers stay armed and ready. The defense never comes down.
Two mechanisms. One compound. No pharmaceutical protocol in standard oncology does both at the same time.
