“the first time i took this i had some numbness and tingling to feet. it does seem to have calming effects. what i would like more information and testing on is the effects of the corydalis at this dose on peoples liver? there are cases of hepatotoxicity with use of this supplement, i want to keep using this because melatonin does not work for me, but would greatly appreciate if their was some research and information done on for the cordyalis.”
