There are more and more remedies being discovered all the time. Two of note being the California Remedies and the Australian Bush Flower ones.
I've tried the California ones, and have felt little or no effect. That's not to say they don't work, just that they didn't work for me.
The Australian Bush Flower ones I've heard positive feed back on, though, I've not tried them and feel no pull to do so.
Update: I finally tried a bottle of Australian Bush Essences. I complete the bottle and found no effect on the desired condition. Whether it was too many remedies mixed in or whether they just don't do what they are said to do, they simply didn't work for me.
I'm not really sure why people are working to discover more and more remedies. The Bach Flower kit is complete. It covers every known state of mind. The plants, trees, etc, used to create them were specifically chosen for their non toxicity. I'm far from convinced that these new remedies are needed or useful, or even what they say they are. I feel they might even hurt an already proven, safe system.
Dr. Edward Bach wrote this before he died.
Attempted distortion is a far greater weapon than attempted destruction... mankind must always have a choice. As soon as a teacher has given his work to the world, a contorted version of the same must arise - the contortion must be raised for people to be able to choose between the gold and the dross.
The same goes for many other things in our daily life. Things such as love, truth, peace, happiness, selflessness are being distorted. Being made to look sappy and weak. There is no greater weapon of destruction than distortion.
