an experimental double blind controlled study was carried out to confirm the effectiveness of the so-called "bach flower essences" in the improvement of memory functions. to this end, a five flower mixture (chesnut, bud, red chesnut, wild oat, honey suckle and clematis) obtained from homeopathic drugstore located in havana was administered to first-year university students at the university of havana. three groups were created, one without treatment and the two other groups received 4 daily doses for 10 days at a rate of 4 drops sublingually of the flower mixture or the placebo in which flower are prepared and preserved. to assess the effect, a memory test (rey′s test) was applied to the participants in the subsequent days. the first day, they were given a list of 15 words and the number of correct words that they were able to remember immediately was recorded in writing. this method was repeated 5 times; there was a progressive increase in the number of correct words remembered. on the following day, they were given some cartoon story containing among other the 15 words from the list and the participants were asked to identify them. the statistical analysis (anova) of the results did not show significant differences among the groups in none of the tests. these results did not support the hypothesis that these flower mixtures have a real impact and suggested that their possible success in some cases be of placebo-type.
