Bach flower remedies (BFRs) are solutions of brandy and water—the water containing extreme dilutions of flower material developed by Edward Bach, an English homeopath, in the 1930s. Bach claimed that the dew found on flower petals retains the supposed healing properties of that plant. Systematic reviews of clinical trials of Bach flower solutions have found no efficacy beyond that of a placebo.

Edward Bach was a British medical doctor, bacteriologist, homeopath, and spiritual writer, best known for developing the Bach flower remedies, a form of alternative medicine inspired by classical homeopathic traditions.
