Roy: Your last line was: "Good science takes time". What a wise man! My compliments to you. Dr. Nick Calderone, formerly with the Beltsville ARS lab, is the replacement for Dr. Roger Morse at Cornell University; and he has devoted at least the last 10 years of research on essential oils. I have talked with Nick about this work on several occasions and "NOT PUTTING WORDS IN HIS MOUTH", he has not been able to recommend the use of essential yet based on scientific findings. Why don't you write to Nick and perhaps you could learn more. And YOU keep up your good thinking! George Imirie, retired scientist, my 65th year with bees
