looking for comfrey in Glendale Arizona

Hi everyone! I need help. My friend lives in Glendale, AZ area. She recently had a back injury and is being bounced around doctors taking prescription drugs for pain. She has learned about comfrey and would like to try using it topically as recommended. We are at the tail end of winter here in PA and I cannot help her out.


Are there any AZ permies in the Glendale area who can help?

Thank you very much!
