There's even some research on histamine - which should please HarryZ.
I find it interesting that the NMSS is funding histamine research for a doc in Italy when they told Elaine Delack (inventor of Prokarin) in their own country, to basically take a hike and stop bothering them about assistance in her histamine work!! They went so far as to tell Elaine that per a study done in California in the 80's, ( horribly designed study on 20 patients) it proved that histamine therapy for MS did not work.
As well, Dr. Hinton Jonez, gave IV histamine treatment to thousands of patients in the US in the late 40's and early 50's. The results were very impressive but when he died suddenly in 1952, all of his research died with him and was never followed up by anyone for years.
I've sent the link to Elaine and asked her to review the info on this.
Thanks for posting this link.
