That stuff has been around some 15 years at least, though the several clinical studies that have been performed have equated the solution to something along the lines of an expensive placebo.....
Despite claims for Rescue Remedy's stress-easing effects, very few scientific studies have looked at the product's ability to reduce stress or provide any other health benefit. Findings from the few available studies indicate that Rescue Remedy may be no more effective than a placebo when it comes to relieving stress.
In a 2007 study, for instance, researchers randomized 111 nursing students to Rescue Remedy or placebo after leading them to believe that they had to take a surprise test. Study results showed that Rescue Remedy did not significantly differ from the placebo treatment in terms of its anxiety-reducing effects.
In an early clinical trial, published in 1999, researchers took 100 students, giving part the Rescue Remedy or a placebo. The study did not detect any difference in efficacy between Rescue Remedy and placebo in the treatment of the test-related anxiety.
