I was researching the use of cat's claw "gou-teng" (Uncaria rynchophylla) for helping with my PD tremors and came across this article: pubmed.ncbi.nlm.nih.gov/364...
It made me wonder what became if this research seeing as it seemed to show promise once they got it across the BBB. Has anyone heard anything new about rhynchophylline, or had good results using U. ryncophylla for PD tremors?
