Clinical verdict
Graviola is the most dangerous 'natural cancer cure' myth. Acetogenins kill cancer cells in vitro but are NEUROTOXIC in vivo — linked to atypical parkinsonism in Caribbean epidemiological studies. ZERO human cancer trials exist. Patients abandoning chemotherapy for graviola face two dangers: untreated cancer AND neurotoxicity. The fruit itself (occasional consumption) is likely safe; concentrated leaf/seed extracts are the concern [1].
