Rescue Night remedy for insomnia unsubstantiated

I had seen advertisements on the London underground towards the end of 2011 for Rescue Night remedy made by Bach which claimed to “help switch off the mind from unwanted, repetitive thoughts and leads to a good night's sleep”. Due to a combination of my science education and personal experience of occasional sleep problems, I wondered what the exact biological mechanisms for “switching off the mind” would be. I emailed Bach, using the ‘Ask for Evidence’ online postcard, to ask them for the evidence behind their claims, and also about how it actually worked. The reply I received stated that “the Rescue Night product is not suitable for use in treating insomnia and it is not advertised for use in the treatment of insomnia”, and advised me to contact my Doctor for insomnia advice. This is disingenuous as in both the adverts and on their website, it clearly states that it “leads to a good night’s sleep.” No information was provided about how it worked exactly, nor any evidence of trials to back up their claims. I replied requesting both these pieces of information and a week later am awaiting their reply. I will be chasing them up on this soon.
