Bach flower remedies 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 dew found on flower petals retain imagined healing properties of that plant. Systematic reviews of clinical trials of Bach flower solutions have found no efficacy beyond a placebo effect.
The solutions contain a 50:50 mix of water and brandy and are called mother tincture. Stock remedies - the solutions sold in shops -are dilutions of mother tincture into other liquid. Most often the liquid used is alcohol, so that the alcohol level by volume in most stock Bach remedies is between 25 and 40%. The dilution process results in the statistical likelihood that little more than a single molecule may remain; it is claimed that the remedies contain energetic or vibrational nature of the flower and that this can be transmitted to the user.
They are often labeled as homeopathic because they are extremely diluted in water, but are not homeopathy as they do not follow other homeopathic ideas such as the law of similars.
Each solution is used alone or in conjunction with other solution, and each flower is said by advocates to impart specific qualities. Remedies are usually taken orally.
