Flower essence-

involves the use of extracts of flowers as a type of treatment for a number of conditions.  The Flower Essence Society is the main purveyor of this alternative medical system.  They have many publications for sale on their website and make many claims.  Their “proof” largely consists of case studies without any controls.  They claim extracts or “essences” are treatments for insomnia, depression, and a variety of other maladies.  There is virtually no scientific proof these treatments are effective.  However they are probably not harmful.  Painbytes assessment is one thumb down due to the lack of science.   www.flowersociety.org
