Bach flower remedies are flower essences developed by Dr. Edward Bach in 1930, which is a herbal medicine to cure and prevent physical and/or emotional disorders by treating our emotional imbalances. Currently, they are becoming increasingly popular and are used by many health professionals, such as doctors and psychologists, to treat anxiety, stress, or depression, despite the lack of biological plausibility for their use. 1
Some studies show positive emotional changes due to the use of Bach flower remedies as a therapeutic agent to relieve pain and balance the emotional state. In addition, there are studies that show the efficiency of these remedies in the control of glycemia, triglycerides, and cholesterol, and also, they can serve as a strategy to reduce risk factors for cardiovascular diseases in rats. In this way, these studies provide some evidence that Bach flower remedies may have some biological effects. 2,3,4
However, as Bach flower remedies are a type of alternative medicine used without evidence to support its effectiveness, many researchers criticize its use in formal health systems. According to them, if a health professional uses this therapy and sees an improvement in the patient's diagnosis, he may believe that this is the result of the therapy used. However, they may be unaware that the improvement may also be related to other factors. For this reason, randomized clinical trials are needed to strengthen the cause-effect relationship.1
Therefore, it is believed that it is important to open the discussion about the use of unproven treatments for the treatment of mental disorders, and the institutions responsible for the population's health must guarantee the best treatments available to patients. Besides, they must inform patients about the effectiveness and potential dangers of these treatments. 1
