Withania somnifera Suppresses Tumor Growth of Intracranial Allograft of Glioma Cells
In this study, oral administration of an ashwagandha water extract to rats bearing C6 gliomas for 21 days significantly inhibited tumor volume. The dose of ashwagandha was equivalent to 140mg/kg dry matter. Using the allometric scaling method that would be in the neighborhood of 1500 mg of ashwagandha (dry matter), but allometric scaling is a pretty unreliable method to determine equivalent human doses.
I've uploaded the study to the Brain Tumor Library on Google Drive. Let me know if you want access to the library.
