Bach flower remedies continue to be popular and its proponents make a range of medicinal claims for them. The aim of this systematic review was to critically evaluate the evidence for these claims. Five electronic databases were searched without restrictions on time or language. All randomised clinical trials of flower remedies were included. Seven such studies were located. All but one were placebo-controlled. All placebo-controlled trials failed to demonstrate efficacy. It is concluded that the most reliable clinical trials do not show any differences between flower remedies and placebos.

In most countries, flower remedies are marketed not as medicines but as food supplements. Therefore there is no legal requirement to demonstrate efficacy and no health claims are permitted. Yet there is an abundance of literature on flower remedies which does make such claims.

When professional flower remedy organisations were asked for which indications they would recommend flower
remedies [26], they named the following conditions: anxiety/ stress, depression, general mental stress, lack of confidence, trauma (emotional and physical), cancer and HIV/AIDS. This systematic review shows that these claims are not based on evidence.
