Although I have tried Bach flower remedies, I have found Australian Bushflower Essences to be very effective. As a practitioner, I have given several formulas for many ailments to my patients and have found them to have a profound effect (in a good way) on them.
My suggestion for the types of Australian Bushflower Essences that may be useful for Social Anxiety/Phobia would be as follows:
Dog Rose - Fearful, shy, insecure, apprehensive with other people and niggling fears
Crowea - for continual worrying and "not feeling quite right"
Five Corners - Low self esteem, dislike of self, crushed or "held in" personality
Grey Spider Flower - if they feel as if harm will be done to them by others if they are in social situations
You should be able to log into Australian Bush Flower essences.com and order the essences in a formula with the above listed flower essences or you can order the concentrated forms and make up more than one bottle. I can guarrantee you will be wanting more than one bottle. :)
All the best, Erica French
