Dear Mary-Anne: I apologize giving you a shock with my revelation that I have tasted most of the chemicals that I have synthesized for the purpose of doing research in pharmacology and biochemistry. I used some precautions when I heard about the Swiss chemist who had the same bad habit; the compound he tasted was LSD. Further, I did not taste compounds of known high toxicity or where only a fraction of a milligram was suspected. I never had any toxic reaction,although one of my close colleagues became very ill from tasting a compound that potently inhibited oxidative phosphorylation, which is very dangerous to the brain. He recovered in 2 days. I virtually eliminated the practice after that (about 1958, when I was 30 years old; I've survived till 67. In response to you and your husband's concern that my chemical tasting contributed to the deverlopment of PD - it cannot be ruled out. A systematic study would have to be done, and that would be illegal today. Since PD is such a complex disease with possibly multiple sites of action, your suggestion is important, but it is not testable.>> >> In reply to Charlotte's queries about my use of NADH for PD: I use none of >> it or ever have or ever intend to.
