I have been trying to find this herb for months. None of my local stores have it. Where did you order it from? Also, would you happen to know - since this is like a beta blocker ---would it degranulate mast cells like betas do? Since I have MCAS and can't take betas - wondering, since it's an herbal if it would have the same reaction. Although, it sure sounds like it would help. Rehumania is much easier to find and is in a whole lot of chinese mixtures. Rama has been talking about these two herbs for awhile and even though he says he has taken them for years - they must not be ALL he needed cause I know he's added some meds to his routine in the last half year. But, it sure sounds like it might help, still looking for my purple bandaid. I hope I can find the Eucommia bark............. Issie Issie: Me too. I have called my local health food store and they don't carry it. I do see that it can be ordered on-line but I don't much about this herb so I don't know which website is best to order through. Also, I had the same question as you since we suspect that my daugther is dealing with a mast cell issue and I am not sure if this would help or make her worse (like beta blockers do). Let me know if you find out anything about this. Thanks! Pam
