Have been battling a nasty bug which has put me in bed most of the time since last week. Developed a nasty cough and much phlem. Hubby went to chemist for me to get a cough mixture suited to a diabetic. Was not supposed to be good for people with BP probs or on anti-dpressants. Chemist said however taken for a few days would not hurt. What has intrigued me is looking at the bottle again just now I discovered the heaviest concentration is of Guai. Anyone else notice that in cough mixtures before? I would not have taken any notice had I not been a part of this board. The phlem etc is certainly better, but maybe thats why I have a herx effect??? I don't know really. Am not up with these things yet.Just found it interesting. Love Ozgran.
