I’ve noticed that several brands make a patent of An Shen Bu Xin. Do any of the formulas not contain pearl? Asking due to shellfish allergy. Thank you!
Not that I am aware of, but there are plenty of formulas that in theory (and with proper tcm diagnosis) would be functionally equivalent to an shen bu xin wan that don’t have pearl - or you could get it custom made without it, but that would most likely not work very well.
