How to Block Histomine for Allergies?

Diamond hydronate was being checked out in 19 forty seven as a treatment for alergies, for hay fever. And one of the patients who they were trialing i in was a pregnant woman who had nausea related to that in car sickness. She took it for the hay fever, but then noticed that when she rode the tram, she didn't get sick. Ah, these were all early attempts that certainly did help with nasa and vomiting, but probably could have done a lot of bad stuff, and did at times. So, early attempts, but not our best effort just yet.
